I absolutely love these videos you make. Specifically the way you show your bugs, fixes, and frustrations. I remeber when i was 12 all i had was the 6809 datasheet and handcoded my asm programs by hex using basic. No fancy assemblers. So watching you do it the proper way has me so longing i had those tools and knowledge when i first started. But it warms my heart to see someone else as passionate as i was. I look forward to these videos with anticipation. Keep up the fantastic work. 😊

An idea for you ... something that might take less processing power *and* extra bytes. Set the "pieces visible" flag to one, and then - when drawing the exploding parts - if one or more is still visible on the screen - you clear that variable rather than add to it.

Great video and thank you for sharing! This is better than watching Indi 500 :D

Nice, I giggled at the end, cause it made me remember this one time I worked out how to fix a bug that had been really eating me and thought great that's that sorted. The next day I was so mad that my quick n' dirty sure fire fix hadn't worked when it occurred to me that I never added it in... I enjoyed the video, thanks

Just great :)

Looks like the vehicle's soul is rising up to heaven after smashing into the rock.

I love the first crash animation. I thought, "Wow. Integrated ejection module!". Nice to consider the driver... or more likely space force wants their seat back.

What happens if you just hold down jump all the time?

First!

I did notice that the -rewind switch was after the -debugger entry you added. It shouldn't matter at all, but personal experience suggests it might be worth trying the -debugger switch as the first then last option in the list just to confirm it's not something flaky like order of operations. Also, those weird double characters - was that worth an ini delete at that stage? I don't think you tested that eventuality either. Good luck!

That haircut is on point.

This is so cute. The pure joy in his voice, when's the last time you felt like that about your childhood computer? Great stuff man. I don't see many channels dedicated to the Coco. I never had one (we were an Atari 800/XL household back then) but I had a friend who had a Coco and I remember playing some cool games on it when I went over to his house. Keep it up!

Regarding writing old games, I can remember playing "Hunt The Wumpus" on a PET and deciding to write down the connections between all of the passages since they were the only rule in the game which I couldn't just remember. Later on (much later on), I used that list to re-create the game from scratch in a completely different version of BASIC. I even came up with a 100-room version for GW-BASIC under DOS. I don't think I bothered to attempt many real-time games using any version of BASIC because all of the BASICs which were on home computers were interpreted, which was too slow to handle all but the simplest animation. I can remember making a version of Dominoes for GW-B which used digits, 0-6, to represent blank to six on the dominoes, and the computer played the other side with the simple strategy of playing the first domino it could find in its hand which fitted. Even so, due to the randomness of the game, it managed to win on average 2 out of every 5 games (meaning that I'd win on average 3 out of 5 games). I've made a version using Liberty Basic for Windows which has graphics, and it follows the same rules and has the same chance for the computer winning. And then there's a version of Galactic Conflict by Paul Alger, which was originally written for the CoCo to be a multi-player dial-up game (with one player at a time). I re-wrote that in GW-B too, and later translated it into Turbo Pascal.

Out of curiousity - did you know about the high speed POKE (POKE 65495,0 and the slowdown to normal speed POKE 65494,0) when you were young? Once I found out about that (around late 1981/early 1982, I think) I used it for everything. Also, on your Oregon Trail style game - GET/PUT on even byte boundaries (and not using the ,G option on GET while doing so) is *much* faster. But you probably already knew that (now). 🙂

I thought that Enemy was wicked fast. If you've got any more of this to share, bring it on :)

This is great fun! I wish I had my attempts at arcade games written in BASIC for the CoCo from back in the day.

Hilarious! This reminds me of some of the programs I wrote as a kid on my CoCo and Model 4…most of which make me cringe now, but it helped me learn. Looking forward to the follow-up!

Those are far better than my attempt at writing checkbook software for my mom. It mostly made snarky comments about the three or four stores that it would accept as payees. Never actually showed it to my mom, which probably was a good decision. Nice that you still have copies of your childhood programs.

Fuck tandy... it's #fucktandy month.

Ótimo video 👍

Ha ha ha, wish I could have somehow saved the programs I wrote on my CoCo2. I had 16K, and I remember running completely out of RAM working on my text adventure. Instead of "look", it had a "scan" command that would make a cool noise every time you did it. I sure had fun with it, but I'm pretty sure everyone else in the house was really sick of that noise!

Oh that brings back very fond memories. I once took a basic programming course at 12 years old at a local university and this was the exact subject material. Thanks 😊

Always fun to look where you came from and where you got. Thanks for uploading.😊

That was fun :)

Hi with just one cable i can play games from my pc on my coco3? do i need the mono sound cable?

The meters are inverted. When a meter of this type is at the top, it means maximum capacity has been consumed (nothing remaining) and when at the bottom, no capacity has been consumed.

At 5:50 "read to or written from" :)

Two very useful improvement that comes to mind is a "frame overrun" counter (how many times it missed the frame time target) and "lowest frame time remaining" (that didn't overrun). Both looks like they should be relatively easy to add with the infrastructure you've already made.

Interesting video. I've only ever done this the old school method by poking address $FF22 to toggle VDG colour sets immediately before and after a call to the render code, to visualise how many scan-lines were taken to render a frame. Also handy for spotting performance spikes without diverting your attention away from the game.

It's fun to ponder what games and other programs would have been written back in the CoCo days if they had access to modern development tools back then.

Very interesting! I wonder about what weird stuff could be done by pairing Lua and Coco that way.

@CocoTownRetro You know what would be a nifty add on would be kinda like a disk activity box that could possibly show the drive #, track, sector, and maybe read/write/trackread/trackwrite functions. There several nifty ideas running through my head :D Maybe even a HDD activity box for the EMUdisk :D

Great video! Thank you for sharing with us your adventures :D Got to love MAME and some of the features that it has that other emulators don't have.

Really enjoyed that. I knew it could be done, but I've never looked at MAME/LUA scripting. This was a really well paced introduction. It's got me thinking about what's possible on the C64 side....

glad to see another MAME video!

Also, if your game has music in the background and it's NOT the CoCo Town theme? I will be very disappointed.

Have you been able to detect if your videos are a hit?

still think you should consider making the wheels/suspension bounce up and down while it goes over the terrain.

Awesome as always, now I find myself constantly jonesing for the next episode every week.

Great explosion animation!

It's looking more and more like something that would have gotten a large ad in The Rainbow by Tom Mix.

@CocoTownRetro Great video as always and enjoy how you present your videos! Keep up the good work! Also have you thought about using the binary %00000000 type stuff in your FCB's to make your bit patterns in your sources that way?

Not a bug!! A feature! 😤😤

What about two rocks in a row, any bugs there?

And that's the hole thing. Adding a rock was a rocky journey, but you didn't hole back. And in the end, you rocked it! Rock on!

in the last run there is a blinky horizontal line right on top of the counter (Upper left)

What do you want to do with your life....

I love this!!!

Great moon atmosphere refraction! Realism always first! :)
