ESP32-Doom available

Postby ESP_Sprite » Mon Jul 03, 2017 11:27 am

Hi all,

Okay, if you happen to have hardware with a rev1 ESP32, psram and a LCD, I have something for you: you can run a version of Doom (the 1993 version, not the recent one) on your hardware!

The backstory, for whoever is interested in reading: Back when we started working on PSRam support for the ESP32, I decided to try and port Doom over to the ESP32, specifically the PrBoom version of Doom. Unfortunately, as you all know, Psram support for the ESP32 has been a slightly more rocky road than we expected, and Doom turned out to be a pretty good indication on if we still had bugs left... it's a pretty complicated program that has a pretty extensive set of memory access patterns, so whenever for example the demo de-synced or the program crashed, we knew we still had work to do. Needless to say: Doom at the moment runs stable on our hardware (as long as you don't try to do something we didn't implement.)

At the moment, the code is capable of running in 320x240 with a speed of around 20FPS. You can actually get a few FPS by clocking the flash at 80MHz instead 40MHz, but because Wrover-Kits do not work well at that speed out-of-the-box, we didn't enable it in the default sdkconfig.

We didn't implemented all things: there is no sound, no music, no savegame support and because we didn't include all data that PrBoom has (because we wanted it all to fit in 4MiB of flash) some menus will crash. Also, because of the 4MiB flash limitation, we only tested a stripped down version of the shareware Doom game data. With more flash, you can theoretically run other game data as well, but we did not test this. In general, this code comes as is: we do not expect to add any more features to it, although we're receptive to pull requests if you do.

A video, for those without the hardware: https://www.youtube.com/watch?v=Gb_JFDa0AIo

And for those with the hardware: the code repository is here: https://github.com/espressif/esp32-doom . Sorry, because of the licensing of PrBoom I'm not sure if we can spread compiled binaries around. The code needs the PSRAM SDK branch (plus toolchain) to work.

(And yes, I know E1L1 by heart now and can tell you exactly how the first demo goes and where it crashes if we have memory problems...)

chocolate doom ESP32 port?

Not sure but i think the needed wad from here can be used?
this is 93/95 public version ( PR version )

not sure which is the right :

FYI: ( german )
doom1.wad public in this PR download version
index.png
index.png (36.48 KiB) Viewed 38242 times
or this ( doomarchive.com ) shareware
index2.png
index2.png (13.91 KiB) Viewed 38242 times
hope this helps.

best wishes

There's a working (and somewhat stripped to fit in the remainder of a 4MiB flash) version of the shareware Doom wad linked in the readme of the Git repository.

Re: ESP32-Doom available

In psxcontroller.c , I can see you still use some delay (with a series of nops in asm) between gpio writes as a workaround to prevent discarded writes in fast, subsequent accesses to the same register.
(alternative register addresses were provided in the "ESP32 bugs and workarounds" document, but i seem to remember this wasn't ideal for some other reason, if you could clarify this point again ...)

Please can you tell us why you are still using this trick with up-to-date silicon, and what is the status of this annoying bug (possibly limiting GPIO throughput) with revision 1 ESP32 ?

Rudi: Hmm, I saw that before, forgot what the cause was... will look into it, I may have forgotten to push my latest changes to Github or something stupid like that. Even without a controller, Doom is supposed to play a few demos.

Nicolas: Because the code is a copy-paste from the NES project, which is pretty old. It's actually not even meant as a workaround for the GPIO issue (which wasn't known at the time I wrote that code), it's literally only meant to introduce a slight delay.

Rudi: Ah, I remember now. (Seems the coffee kicked in.) That was a small bug in the mmap code of esp-idf that I fixed just before releasing Doom; if you are still on an old version of the branch you will see that. Please git pull in the esp-idf directory and recompile to fix it.

@Sprite: ok sorry, with the delay between writes to the same register, and the "nops" sequence, it looked very similar to the code examples previously provided as a workaround (I hope the bug has been fixed in the new revision though).
