You know what? This concept would work really well on a modern game as well. I'm almost imagining a current gen game where you'd enter a robot factory and had to eliminate robots and solve puzzles in order to reach the next level. Solid concept and looking forward to it!
Yeah it exists, kinda is the whole plot of Portal lol. Only you don't have a proper gun. His idea is still very original though, awesome!
I love that you made the difficulty setting makes the robot more angry. Reminds me of the difficulty settings in Wolfenstein3D and Doom.
Indeed.. That is where I got the inspiration, only it's backwards because it is showing the enemy's face instead of the player.
Reminds me of Jazz Jackrabbit 2
Maybe it was a reference 🤔 😉
For me i recognised it from LHX Attack Chopper.
For me it were the tiles at 1:17 that made me think of Wolfenstein.
8 bit guy: so I have this idea for a game
8 bit guy: alright here's an advanced prototype ready to go on 3 systems
Including map editor and custom developer tools
For the past 6 years I've been writing a text adventure for the PET. I think I've just about got the title screen done.
Including Map editor, custom developer tools (Bram Beirens) PLUS a Snes to 9pin adapter for Snes gamepads...Just wow...
8 bit guy: also, I will be making versions for a half dozen other systems and will add SNES controller support
Got my pack of paperclips, where do I plug them in?
As soon as you have an idea for a game, you've got a prototype ready within seconds.
It's genuinely amazing how with old, simple computers like this, you're making the game as you're working on the concept.
Nowadays you want to think on a game for months, then do simple demos... Then years later it's done.
But this will be done in what... A year? Two?
Not only because you're skilled, but because it's simple.
The better games got, the more points of failure.
Grew up on the C64....and it took 35 years for me to see what it was capable of. Thanks, Dave!
Lay of the haterade. Let me see your code!
this kinda stuff makes me really want to pickup a mini pet.
Are you talking about a small pet or a computer?
@@markusTegelane The mini-pet kit from tfw8b
Very cool but I think making fire with the wasd keys instead of classic movement is a huge mistake as most people associate wasd with movement
LEGO STAR WARS TCS
They're overpriced. Don't.
David today: Yay, I made a new game!
David in 5 months: There are so many packages to pack and ship out, what was I thinking!?
that happens every fucking time and yet david still makes games,im glad he does
Predicted the future
Average David Murray development cycle
Hello, please reconsider reimplementing the shift+wasd for movement and shoot. I don't have the use of two hands and that would be a great accessibility option. Thanks.
How do you game with one hand? When I radially dislocated my wrist I relearned to hold my controller and managed to push buttons with my ring and pinkie finger but I did have at least that. I'm very curious about true one handed gaming. I am aware a keyboard may have advantages but I assume there's also unique challenges by comparison to a controller.
As a modern programmer, I feel like we are missing something nowadays. I feel like your program that is "closer to the metal" has a feeling to it that you dont get any more. I was writing in python while watching this and I wish we had some of the feelings back if that makes sense.
I think that is exactly what David is trying to get back to with the Commander X16 project which I am equally excited for
which makes me think... The most modern OS with closest to metal API must be TempleOS, right? I wonder what David thinks about it, and whether he'd consider tinkering with it a bit.
@@mfaizsyahmi Out of interest where has this widespread fascination with TempleOS come from? I swear it used to be an occasional throwaway comment but I've been seeing it pop up all over the place recently.
Drop python and go back to c, if youre doing graphics programming try out raylib. It’s got the advantage of being new and modern but still really low level
@@Daeraxia TH-cam has been recommending a lot of videos on it over the last quarter. I know there was a longish YT documentary on it. The thing is that TempleOS sucks ass.
I love how obviously proud he is of the game's complexity. As someone who loves writing complex code solely for the sake of complexity, I can completely understand being proud of that.
Wow, looks awesome! Wish I had a PET though. :'(
Hey look! It's squirrel monkey
No way, that's@@kikoplays44!
Emulation, my friend. Emulation
wait when did squirrel monkey like 8bit guy
@@winksplorer I always liked him. Even made a video about him. :)
I'd suggest remapping movement to "IJKL" instead of "PL()", as that's what many games already use when there's no numpad available.
And if you're playing the game on an emulator, you might have keyboard layout issues with ( and ), they're under Shift+8 and Shift+9 on my layout...
Exactly, WASD is the standard set of directional keys and IJKL is the standard secondary set. I'd also recommend using WASD for movement and IJKL for shooting, rather than the reverse, since that's more expected as a standard.
also () won't work on most nordic keyboards
With this setup it then makes sense to then use the number pad for firing, otherwise it’ll get uncomfortable
@@deanolium "Tenkeyless" keyboards are pretty common these days, so a number pad might not be available. WASD+IJKL would be a "safe" default layout, since those keys are in the same positions on all keyboards.
(Unless you're not even on a QWERTY layout, but then you're probably used to keyboard layout issues in games, and the keyboard config is the first place where you always go).

Hey how are you? My Name is Michael im from Switzerland, and i wanna say thank you, your Videos really helped me to learn English. And you Make great Videos. Hope you and your family are good in this difficult Times. Sorry my English writing is not the best.
Thanks bye
Writing is very good 👍
Just wanted to say I found out about the vice article, and it sucks that people are trying to drag you down. I love your content, mistakes and all. Don't change for anyone but yourself. Thanks for your uploads, and God bless.
Can't wait for this - it's so great you dedicate so much time to making these games for vintage systems.
I'm an Android developer, this has inspired me to code a retro game for Android
What games have you already made so far?
Thank u sir... for your opinion
I'm a beginner wannabe Android developer, I wanna know how to start thinking about like retro looking design? Do we use unity or something? Or is Android studio capable of building retro-looking games?
@@visiongt3944 Well you can just use OpenGL ES through C++ or through a Java GLSurfaceView.
True, These kind of videos are always both entertaining and inspiring !!
David Murray, this is glorious! Never quit doing what you do.
I love your videos are having surprisingly calm intro music instead of bullpoop loud 28th century musics
Hey Dave. I just want to say I love your videos and you have done more for the vintage gaming and computer scene than so many people could even dream about.
Please keep doing what you do!
Those graphics look awesome! I love the door animations and the level reminds me of Scumsoft from SQIII
The number of things that the 8-Bit Guy can do blows my mind. This is amazing!
Thank you for all of your videos you post! I thoroughly enjoy them and have learned so much from you. Keep up the good work!!
There's a magic and simplistic beauty to these old games that I really love. Nice work!!
I wish I knew how to help with the art aspect, but I'm loving what you've got so far!
i'm so glad somebody took on the challenge of programming a really good game for the PET! it's such an interesting machine for me and it almost makes me wanna pick a MiniPET to play around with it
Your ambition and productivity are very inspiring as always !!! Nice to watch the work of the master =)
Thank you so much for the video and GOOD LUCK in developing the game !!!
No kidding, you are BRILLIANT!
I love to see what you're up to. I don't have any of the old computers you do, and being a few years younger, pretty much never have used them. I also have very limited (computer) gaming experience.
Still always love to watch The 8-Bit Guy!
Please add CB2 sound to the PET versions, possibly as a small addition the the SNES User Port card.
I had no idea the PET had any sound at all, but a quick web search shows that the user community had discovered sound was available out of the CB2 pin on the cassette port in 1978. I guess this would chew up some CPU resources. If adding the resistor, headphone jack and piezo speaker parts are too costly, perhaps the PCB could just have the traces with NOPOP options on the components.
Maybe David could use CB2 sound on all systems if the SNES card is bundled with the game. I hope if it does he uses an aux/composite port instead of a piezo speaker.
@@BalugaWhale37 I remember my jaw dropping when I heard the digital samples audio coming out of the Apple ][ speaker with Castle Wolfenstein -- pretty impressive considering it was done with a "push-pull" interface (e.g. you send 0s and 1s to control port to vibrate the speaker) I also remember the method of getting audio from the TRS-80 Model I by sending 0s and 1s to the cassette interface. A portable AM radio could be placed near the cassette port to pick up the RF interference from the circuitry. A better solution was to get a mini-amplifier/speaker and connect that to the cassette audio connector. Of course in BASIC the best you could achieve for audio was a low-frequency buzzing noise.
Eric Hollas Later models have an inbuilt piezo speaker connected to the timer2 interrupt. And you can play back samples through that as well. Check my demo OOBC: We are computers.
@@makipri is the source available? I've just started down the rabbit hole of 6502 Assembly and find studying others' code useful. Even moreso if it's annotated.

Tip from a gamedev: IJKL is the accepted standard for "opposite WASD" input
OK, good to know. The controls aren't set in stone yet.
Reminds me of a certain text editor
Edit: on second thought, not quite :)
@@enjibkk6850 game idea: invader vim
A good reason for this is that, for emulator qwerty players, the symbol beside the "L" key varies depending on their regional keyboard distribution, so "L" is the most practical middle-row key to the left for use.
@@enjibkk6850 IJKL is so going to annoy all the Vim users 😅
Hello 8-Bit Guy, I'm from Brazil and I discovered your channel about 20 days ago and since then I've run a marathon, watched from the first video to this one. Congratulations on the work, I learned and had a lot of fun so far. Hugs!
These explanations really help me understand the "why" questions I had years ago when playing games on these computers. Thank you!
Dude, you are a legend. You seem like such a chill dude but you are a monster at getting stuff done!! Very impressed with you channel
Looks really cool. Love the portability. What about color 80-column mode for the C128? There are a heck of a lot more C128's than there are 80-column PETs or B128s, and it would have the highest color resolution of any of the Commodore platforms. Plus the C128 has independent cursor keys AND numeric keypad AND a SID chip.
Brian H And 2Mhz in 80 col mode 😃👍
That was exactly the question I had. 🙂
But the video chip for the 80 column screen, the VDC, doesn't share with the CPU the memory mapping like the other 8-bit CBM platforms do. The 8bg would need to rewrite the scroll routines and so, and I don't think there's many people out there with VDC programmings skills to help out.
Spy Robots VS Spy Robots :-)
came here for exactly that comment! show us C128 owner some love too
David these videos suit you best mate , love your development videos vs repairs . awesome video
It's my birthday today, and honestly, what a beautiful gift to get a new video from The 8-Bit Guy, specially so close to the last one!
Great as usual!
Happy Birthday mate!
I think that by using the PET characterset, you've created a unique retro-nostalgic aesthetic that looks amazing and will very much satisfy C64 users IMO.
Here’s a challenge: Attack of the Petscii Robots For Timex Sinclair 1000
Possible. But it would demand pseudo hires, which is tricky, because the ZX81 has no diagonal lines in its character set. (Also, it would be in Z80-asm instead of 6502-asm, of course. So no code resuse.)
@@herrbonk3635 Why would it require pseudo hires?
@@kimgkomg Again: Diagonal lines. But the slash character could perhaps do as an approximation? It depends on how nice you want things to look.
Thanks for these great videos David. My two kids and I never miss an episode. Always entertaining and informative.
this is awesome i can't wait to see how the game progresses. What I really liked about the planet X3 "documentary" was the production process in the 4th part. I know it's early but i kinda hope to see something similar with the series :p Keep doing awesome stuff like this it's great :D !
This is actually pretty amazing. I bet this would've been a million selling game back in the day.
Maybe. The one factor I see is that retro graphics were not a good or desired thing in the 80s (graphics could make or break things back then) and this would come off as looking very primitive on a C64. That would massively hurt its appeal, in my opinion. The C64 would be the main driver of sales, due to their market share. If he used sprites in a graphic mode, though, I could see people going wild for it.
I love how the whole point was to create a game for the Pet but you got so into the game itself that you got excited about what the C64 could bring to it. Hehe.
I have to say. I love David's videos. To me they feel like cold rainy weather with hot cup of tea and a blanket. Its weird but that's how I feel when I watch it. Total bliss!!!
Hitting it out if the park! Just awesome. Particularly when it comes to next-level like all those time saving editors you’ve designed. Just amazing.
This is a really inspiring video to watch, and the game looks awesome, especially within the limitations of the hardware!
You should add a paperclip as a weapon to instantly shorten the robot circuit.
damnit you stole my line!
@@kenjpuckett Gold, or would that infringe terry nation cybermen death routine? Actually licencing the concept to BBC for Dr who enemies would give some good overlays (crying angels - plunger and electic whisk welding bug eyed monsters !)

LOL! I knew this one was coming. A Dremel ought to come in handy for cutting open power supplies as well.

It's nice to see that you now upload more frequently. Nice job. Can't wait for part 2
I really love this project you're working on. Programming is so much fun, and old computers just have a cozy feeling to them
Very ambitious project. I wish you the best of luck!
So brilliant! Your imagination and the drive to improve, try something new, are admirable. I regret giving up on programming on C64 after my first failure, at age 9 or so. Didn't really pick it up till my thirties on PC. That said, I did enjoy my C64 a lot in a creative way, nonetheless. I loved doing weird little drawings of cartoon characters, right on the prompt screen. Text mode offered some cool possibilities, too. I might be remembering it wrong, but wasn't there a key that upon pressing changed whatever you typed in into an alternative set of characters/glyphs.
David, major kudos to you for your passion and skill in creating these games!
this looks super cool and I'm excited. also, the short circuit animation really satisfied me
A recent Adrian Digital Basement mailcall had a SNES controller device that plugged into a C64 using both joystick ports. You might want to look into supporting that, too, if possible.
This will be a amazing game. Keep the great job Dave and the cool videos, ignore the haters. We love your channel ❤️❤️❤️❤️❤️❤️ all the best from Portugal 🇵🇹🇵🇹🇵🇹🇵🇹
I'm amazed at your patience and perseverance to make this game run on so many different machines!
Programming on the classic 8-bit machines always had its own special appeal. A friend and I were just barely starting on making something for the Apple ][e before he moved away, so it was abandoned completely. I can’t wait to hear how your game turns out!
Imagine if this game had been around in the 80's! It's really amazing what he managed to do with so little to work with.
Whilst I agree, try and remember that he's standing on the shoulders of giants. It's extremely impressive and I'm glad that he's doing this but it's disrespecting the early programmers who had *nothing* to go on to suggest this is amazing.
I find it amazing how David can dedicate himself to projects like that and keep improving. That's some strong willpower right there!
And build a new studio !
It looks fantastic. The 3D effect and the way the main character moves is so clever. So many other surprising things too. Cheers
It looks really good. I'm amazed at your designs finding ways around the limitations of these systems.
No new posts in a while. Is everything okay David? Hope the family is healthy and doing well.
Probably because our community was cruel to him for bs reasons over his last videos. That would de-motivate anyone and he didnt deserve it, hes probably taking a well earned break. Hes been putting out amazing videos for years. This channel is one of the driving forces behind a lot of love for DOS and Commodore era collection and preservation. David ignore the trolls.
@@jamescurrie01 I thought the building a new office was really cool.
hoping he's back soon with new videos !!
@@jamescurrie01 The community was not cruel to him, he did it to himself and he lost subscribers due to what he did.
@@guayabito6946 What are you talking about? What did he do in his last video that caused so much backlash? I thought his last video was great.
I don't have any 8 bit machines and never had enough interest in them to get one, but this game looks like I might be adding a c64 to my collection.
oooor you could use an emulator
"collection" with no other 8-bit machine

Check out ther MiSTer FPGA project. There are lots of 8 & 16 bit cores available and given its hardware simulation rather than software emulation it feels more like using the real thing.

The answer is yes, by the way.

Back in the day I remember being impressed by how creative people were with ASCII art but this takes it to a whole new level. Awesome work!
The pet version is the most fascinating to me, I love the way it looks.
A w e s o m e. A proper game for the PET! Looking forward to reading about acknowledgements for a game that works and is fun and complex on all the 8-bit commodores.

This looks awesome! I don't know how you manage all your projects to be honest, without getting burnt out - can't wait to see the next update.
My man. This is awesome! Great job, keep up the good work Dave.
I would definetly change the FIRE and MOVEMENT keys, since most people nowdays use the WASD keys in games to move around
Yes, I can imagine this setup with wsad used for fire would crack my brain in half
Agreed
yep
Thought the same, makes sense to swap or use wasd move ijkl fire
He literally said in the video there will be custom key bindings
Whenever "It's kind of expensive" is said I am always like, "Dave have you looked at what functioning vintage anything costs these days?!?!? It's a bargain!"
A PET costs 2000 dollars mate.TODAY !

@@cyuiyuwyguiyui8540 Exactly. These newer products are cheap in comparison.
This is such a joy to watch. David, you're an inspiration!
I just love this channel. Good work
This is one of the most impressive hobbyist games I’ve been seen, keep up the work this looks insanely fun!
in most modern WASD games, E is used to interact with objects. Might make sense to change Move from M to E
Yup this is what I was going to say. WASD for moving your character E for interact. Shift makes sense for moving objects just because it's another common key.
Back in 83-84 I made C64 board game called Drunken Bum. The object of the game is the Bum travels the board to collect bottles and scrap that he can redeem at appropriate board locations, but there were challenges to that redemption along the way. There was a full simple board layout and the spaces you landed on expanded to show a specific action for that space. For example, if the Bum had collected any bottles, he would lose a randomly generated number of them if he landed on scrapyard and received the "guard dogs find you" random result instead of the "find 1 lb of copper pipe". Other pitfalls were landing on a space with police and they take you to the dunk tank and a fine is taken from you. Eventually, you ended up with enough money to go to the liquor store for a bottle of whiskey and the game ended. I had that game saved on a cassette until the 90's, when my younger brother used it for a mix tape.
Loving the progress so far! seems it is going to be fun to play and i love how the "graphics" turned out
Wow, looks pretty interesting! Well done!
The Legend of Zelda: PET of the wild
Instead of compositing tiles and sprites into an offscreen buffer, why not composite the sprites as you draw the tiles? You could probably make this efficient by keeping track of a list of the start addresses of each span of visible sprite data (stored in ascending order), and every time you hit the next address in the list, draw the row of sprite instead of the next couple of tiles, and advance the “next sprite address” pointer.
I have actually considered a method similar to this. I'm still thinking about it. The trick is, as you guessed, not to take too much CPU time between tiles trying to figure out what to draw.
@@The8BitGuy Instead of having a 1000-byte character buffer, you could work everything on the tile buffer that has the size of the amount of tiles on screen, which I guess is 77 bytes. Prepare the 77 bytes with the map information, then overwrite it with "sprite" tile numbers based on their coordinates. Only then draw the screengraphics based on the tile buffer which will do everything in one go. This can be done as I'm seeing the "sprites" are always fixed to the tile boundaries, effectively making the sprites just tile variants. This is the way Ultima games work. However if your background tiles and sprite tiles together exceed 256 variants, then you may have to rethink the tile buffer.
@@zygocact5947 It was because of the environmental setup puzzles and also wanting to make a pun on the PET. Calm down.
@@The8BitGuy I thought I saw someone mention this in a comment yesterday but I can't find it today, so I'll bring it up again. I'm pretty sure the PET has a 60hz interrupt that fires when the machine enters the vertical blanking area. I'm curious if you're timing your screen updates to track that or just doing them asynchronously. It probably doesn't matter on most PETs because I think all models since the "Dynamic Board" have their video set up so it's fully synced with the 6502's duty cycle and non-conflicting, but I believe on the original models with very slow video RAM you can get "snow" if you update when the raster is in the active area.
@@zygocact5947 I am not saying that at all. Just that I was reminded of it.
There's more than one game that does the same thing. It's okay for people to like different things than you.
There are few things that make me happier than seeing new games and accessories for classic hardware. I'll definitely be following this!
I still think there's much hidden potential in the Sega Saturn that is not yet fulfilled, hopefully with the recent hacking of it there will be some homebrews coming around soon
This is really good! I have been playing video games since the late 70’s and I remember how hard it is to program the home computers of the day. I had an Amstrad CPC464 and spent hours typing basic games.
Keep up the good work my friend ✊
Great job! Hope the studio construction is going well.
I'll never stop being amazed at how much stuff he gets done and how quickly. Also, I wonder if this is the new studio and he set it up to look like the old one.
You never cease to amaze me. Really impressive demo so far.
This is incredible, kudos to you David!!!
Now I have some motivation to get my pet’s keyboard fixed!
The programming looks great - simple and effective. I have not written any code for a Commodore machine, as I was mainly a CoCo programmer and wrote many programs for the CoCo - my first computer and inspiration to computer programming. I haven't written anything for a long time, but you have inspired me to find my CoCo and write some code. Thank you.
Wow I haven’t watch any of your videos since 2018 but I’m glad your still making videos
Doing a great job man! Thank you for everything!
i'd like to suggest you swap the movement and firing keys. wasd for movement is so universal in modern gaming, it would be much more natural for most people if your control scheme followed that.
Was thinking of this as well, WASD is so common for movement (for a modern gamer at least).
he said he'd do user-customizable controls so...
I agree. Most twin stick shooters/FPS will have left stick as movement, right stick for aiming.
@@joshuavincent7884 even if they're customizable, it still makes more sense to have the default be the one that makes the most sense to the most people, to reduce confusion/frustration.
As someone used to playing old-school Windows games with the arrow keys (games that were made long before WASD was popular) I do like the current control scheme though.
In any case, user-definable controls would be the way to go
This guy's really living the dream. Full time TH-camr who makes games for the old systems he grew up with.
Makes me wonder how he does his taxes. What does he have to tell the IRS that he does?
Self employed. Probably an LLC/SCorp. Videography? Computer Repair?
Kudos for planning on offering customizable movement/fire keys. I was worried the whole time you were describing the different keyboard setups, until you said those magic words.
This looks like a really cool game, David! Keep up the great work man! I have NO knowledge of old computers, but this looks like it will be so cool to play!
I got major Ultima I nostalgia from watching this.
The limitations of that system really gives you good boundaries to work with and develop ideas in peace. Modern systems have way too much to give and the problem comes down to where to draw the line nowadays. Too much options and possibilities that it's overhelming.
And the limitations are part of the fun :)
Exactly! That's why I love coding for older computers. Not only do you have boundaries but you can also figure out ways to exploit features that maybe nobody else has thought of, which is fun!
@@The8BitGuy *Agreed!* and as you mention its an awesome way to show off not only what the system is capable of doing/producing but what you can do to push it beyond its limits that no one never thought of as well to show off the extents on what they can do!
You could try some fantasy consoles like pico8 or tic80.. They're artificially limited "retro like" platform but with the comforts of todays computers
@@msx80 I have tried Pico before. Maybe I give it a try again. Never really understood the potential of it before.
Twin-stick adventure game? I think you invented a whole new genre!
Also, I really love the stars over the robots after you shoot them. Very effective!
*This is just impressive. I ❤ the thought & effort put into this.*
This looks really great!
Very cool! I would love to see a way to take control of the robots somehow. A terminal perhaps? And use them against each other.
That should be the unlock when you beat the game
I would have been all over this when I had my Vic 20. Well done!
I just want to say that I really appreciate your videos and think that you are a brilliant person.
