ESP32-DOOM, a port of PrBoom to the ESP32
=========================================This is a port of PrBoom, which is a port of the original 1993 ID software hit game Doom, to the
ESP32. It runs on an ESP32 which has 4MiB of flash and 4MiB of PSRAM connected.Warning
-------This is a proof-of-concept and not an official application note. As such, this code is entirely unsupported by Espressif.
Compiling
---------
This code is an esp-idf project, but due to the use of PSRAM as generally allocatable memory, as of the time of writing
of this document you specifically need a PSRAM-capable toolchain and esp-idf version. See `this thread `_
for more information on where to get this. Obviously, you also need a board or module with both an ESP32 as well as PSRAM, like the ESP-Wrover
module or ideally the Esp-Wrover-KIT development board with an ESP-Wrover module fitted.Please run ``make menuconfig`` before compiling, and browse through the options in the ESP32-Doom platform-specific menu. You may need
Controller
----------
It is possible to play Doom using a PlayStation 1 or PlayStation 2 controller. These are the default GPIOs ESP32-Doom expects it to be connected
to, although a different pinout can be selected using ``make menuconfig``.===== =====
Pin GPIO
===== =====
CLK 14
DAT 27
ATT 4
CMD 2
===== =====Also connect the power and ground lines. Most PS1/PS2 controllers work fine from a 3.3V power supply, if a 5V one is unavailable. Note that the
default controller connections are different from the one used in the ESP32 NES-emulator, because GPIO16 and 17 are occupied by the PSRAM.Flashing
--------The main Doom binary can be built and flashed using ``make flash``.
Doom also needs game data, and ESP32-Doom expects this data to be put in a separate partition. In theory, the game data can be the wad from any
Doom/Doom2 version. However, for a 4MiB Wrover32, only a cut-down version of the shareware game data will fit. You can download that data
`here `_ and flash it into the ESP32s flash using a command similar to:``python $IDF_PATH/components/esptool_py/esptool/esptool.py --chip esp32 --port "/dev/ttyUSB1" --baud 230400 --before default_reset --after hard_reset write_flash --flash_mode dio --flash_freq 40m --flash_size detect 0x100000 doom1-cut.wad``
If you want to use a commercial variant of the Doom game data (doom1.wad, doom2.wad, ...), you will need an ESP32-Wrover with 16MiB of flash.
To flash it, it should be sufficient to modify `partitions.csv` to increase the 'wad' partition to a size that's big enough, then flash in the
data file using the above command line.Known Bugs
----------- Because PrBoom expects its own data in the available .wad-files but these aren't available in ESP32-Doom, some features may crash the program. In
particular, bringing up the majority of the menus will cause a crash.- ESP32-DOOM does not support sound or music.
- ESP32-DOOM does not support saving or loading of savegames.
