This makes me want a mini handheld made specifically for Doom. Kinda like one of those those nostalgia pandering fun sized "retro" game handhelds you see at Target but better. It could come pre-installed with Doom and Doom 2 but if we wanna go crazy maybe it could load your own levels from a microSD.
Btw, I am going to make this cool thing, and I have a question. Can you switch guns? I can see only 6 buttons: look left, look right, walk backwards, walk forwards, shoot and use. Mabe dooble click on eof the buttons do it, but can you give me an answer please.
Could I ask you to share bin code for this project please? Sometime it is quite hard to get correct compilation of the project from source codes but it is very interesting to see my favorite game on ESP32. When I was yong it was the best game on IBM Pc 386DX computer :)
My home made solar water heater controller runs on an ESP32. I think I need to upgrade its capabilities. I'll have to get some proper arcade buttons though. Those clicky buttons are really irritating, and the click mechanism slows down their action.
I was thinking of doing this project too haha. I got Quake to work on my STM32479 Discovery and was thinking of going lower end. Did you have any problems with the spi? That is, are you using the same SPI bus on both the RAM/FLASH and the LCD?
ESP32 has 3 SPI buses. RAM/onboard flash always share one. For this project LCD and SD are on the other 2 buses. I've started using LCD and SD on the same bus, and mutexes (see Odroid-Go videos) , It's not really a problem for games like Doom, Duke3D. They load as much from disk to RAM as possible at the start of the level, then page in if it didn't all fit.
@@GadgetWorkbench Hi, thought I should update. I did get quake running but it was choppy. I busted my kit and moved on sadly so don't have much in the way of video. I did however, get Doom running on the discovery before it died and got even music to work. Only reason music worked though were the dsp instructions on the arm. Being able to merge 16 channels (8 per ear) using only 7 thumb instructions per sample helped ALOT. I learned why DSP instructions are so important that day. Still had to run the sound at 11khz. Even though the midi samples I had were at 24khz, started to studder a bit. I also discovered why the music library that was with doom at the time was 3rd party instead of inhouse.
Hello, I'm interested in doing it, but I have doubts about how to use the SD card and how the programming would be, I don't know if the SD card has something to do with the operation....
Great project! I've ordered the needed parts, I need to build one too! Is it possible to run DOOM 2 instead of DOOM? One technical question: those TFT displays often come with an embedded SD card reader; is it possible to use it, instead of an external one?
Holly... Performs at least as good as my 486 PC for over 1000$ back then... At the costs of power cable. I knew It has decent performance but it is quite impressive. The only issue is no proper keyboard to strafe, run, change weapons and so on...
Thanks, I've updated the links with a schematic. Although I don't have GPIO12 and GPIO4 from the SDCard to the ESP32 (these are required for 4-wire SDMMC, but not exposed by my SD card breakout.
@@GadgetWorkbench So there should be around 32 FPS at 40 MHz 320x240 with RGB565, but it seems to be around 7-10 FPS. Why is it so slow? Is MCU unable to handle the game.
@@GadgetWorkbench But why did you put PSRAM on VSPI? The internal WROVER PSRAM was not enought? And, AFAIK, SPI driver can set different speeds for different devices on the same SPI bus.
Sorry - I did not put any additional PSRAM on it. To run the internal PSRAM at 80Mhz, you need to use one of the SPI bus' as a clock for it. I assumed this means you would not be using anything else on that bus.
Great work, Just one question. I have built my own mini handheld (I use a PSP thumbstick rather than buttons) and my LCD is connected to some different pinouts (it follows the pinout of the ESP Wrover Kit V3) with sound on GPIO27 and my SDcard is connected through Think it would be much work to use a different set of Pins other than changing the pin assignments and the code/DAC pins used for input?
Thanks. The LCD and SD Card should be OK with any SPI pins, although if they're sharing the same SPI it might slow down - as files load during gameplay. For sound I use I2S connected to the DAC to handle DMA buffers for me - the documentation only states that this works on pins 25 or 26. If pin 27 doesn't work for this, you might have to re-write the sound output...
I should be okay as my LCD and SDcard dont share any pins (my board is a TTGO T8 v1.3 with SDcard on IO2/4/12/13/14/15) so should be okay. I'll have a play and see if I can get up and running without sound and take it from there. Thanks for getting back to me :)
Nice. Is there anywhere full-size DOS emulator with SD card support? Just to launch any old game or dos program from SD-card... (with an ability to download anything there)?
I'm an arduino beginner (with couple of own completed projects) and I would really love to replicate what You did there. I have some hard time understanding schematics (some parts). Question (if you would be so kind to answer, or point me to a web article explaining): Why did You put resistors on SD card lanes and one one the LCD connection? (I can understand the logic behind keys+resistors). So far I was succesfull getting LCD, amp and SD card working on their own (no resistors). Just would like to know what's the benefit/reasoning?
Some of the GPIOs have a mix of weak pull-up and weak pull-down on reset. I was having issues with the SD card working correctly without these hardware pull-ups. If you don't have issues, then they are not needed.
Hi, thanks a lot for the information. Do you know how to detect when the SD was removed o extracted and when it was put on again? for example, it is working normally and it is on, but someone wants to extract SD and does not turn off the device and then put again, so dont work well, but if i detect that was extracted i can do somethink. do you know somethink like that?

I'm gonna document my current issues/questions here. I am now some sort of DEV in my day job. However I still cant get this badboy project to work. I have several questions about the presentation to the WROVER 1. On the SD card, is the formatting Fat32, or other, also the files on the SD card, does the machine look for DOOM1.WAD DOOM.WAD or any *.WAD files. 2. For the SD card reader. I notice that your interface in the schematic is DAT2,DAT3,CMD,VDD,CLK,VSS,DAT0,DAT1,SH1,SH2,SH3,SH4,SH5, However in your actual physical model you are utilizing a standard SD card reader. They have appropriate mappings on the WROVER module but do not map to the model of SD card reader or any others I can find. 3. There are quite a few resistors in play on your physical model however the Card reader you've chosen and many others come pre protected and packed with resistors. Are these redundant? 4. Finally, what is the expected behavior onscreen if the machine boot successfully however there are no Wad Files or are unrecognized. "Grey screen"? This concludes my questions. I've successfully flashed binaries to a WROVER module however I think Im missing a few details. I've checked all through the source code for a DOOMWADDIR, however I can't find any declarations involving file name expectation.
docs.espressif.com/projects/esp-idf/en/latest/get-started/index.html The ESP IDF is the most powerful and flexible way to compile and flash the ESP32. If you're after a simpler method, you could try arduino....
Dude, I've been at this for hours. (Edit: Days) I cannot for the life of me figure out how to make the file from your source code. Esp32 IDF just says no Cmakelists.txt. Should I be using VScode for this? I've got the chip all booted up and communicating over serial but I am unable despite hours of trying able to figure out how to use your code. I cannot run make in the ESPIDF. I am tracking everywhere you've spoken about this online but I am not having any luck. I don't want you to do it for me but could you point me in the right direction to make the file?
This project was made with an older version of esp-idf - before they started using cmake. docs.espressif.com/projects/esp-idf/en/v3.3.4/get-started/index.html I think you'll have to download an older esp-idf, or use a new idf and create the cmakelists file yourself.
@@GadgetWorkbench Thank you. I managed to get an older version that uses GNUmake. My complete lack of experience super highlighted here. I even purchased all of your parts, including the wrover. Do you have an email where I could just send you like 100 bucks and buy the prebuilt files off of you?>
I've uploaded the pre-built binaries to the Git repo.

Maybe you could start by building simple projects.
@@GadgetWorkbench I literally love you. I was in a bit of a rush with the last comment. I was successful in getting the older espidf, however there were many dependencies that from my limited experience would require an older version of many of the prerequisites. I made many attempts to compile with the older flashmake but what I'd configured kept failing to compile with certain files gpdstub.h and others. I am extremely thankful that you did that! THANK YOU! THANK YOU! I've done many a project with the esp but they all used arduino IDE. Thank you again!
Wow it runs so buttery smooth...it's even better than my old 386 PC from back in the day.
It would be a lot smoother, the micro is pretty powerful, but the SPI LCD can only be refreshed so quickly.
My 33 MHz 386 could run Doom smoothly only when the screen size was set to minimum... Full screen was like slideshow.
I still remember how was waiting over 10 min to load and start on my old 386 SX PC :)
This is an awesome way to learn how to connect various peripherals to an ESP32! As a bonus, you can play DooM if you do it correctly!
Awesome, runs better than my 386 did back in the day!

Can we have RCA or VGA output instead of lcd?
