# Doom!
This is Doom for M5 Cardputer

Cardputer does not have PSRAM, so things get tricky

Is mostly a port of [prBoom Port to GBA](https://github.com/doomhack/GBADoom) by doomhack

HAL was taken from [M5 Official User Demo](https://github.com/m5stack/M5Cardputer-UserDemo)

Some parts collected from [Retro-Go](https://github.com/ducalex/retro-go) project

Can work with original WADs after their conversion with GbaWadUtil, also lended from doomhack.

WAD is compiled into binary itself

Built against
[ESP-IDF v4.4.6](https://docs.espressif.com/projects/esp-idf/en/v4.4.6/esp32/index.html)

Save-load works with SD card

Save-load crashes without SD card

Sometimes crashes randomly
