This port is now abandoned.

I have made a new port as part of Retro-Go. Memory usage has been greatly improved and stuttering has been eliminated.
Retro-Go can be built with only DOOM enabled so there is no point in also maintaining this standalone port.

Description

This is an improvement of doom-ng-odroid-go which itself is an improvement of doom-odroid-go.

New features

  • Full sound support
  • Save games
  • Brightness controls
  • Volume controls
  • WAD selector on start
  • Mods support (Limited by available memory)
  • Cheats menu (Options -> Cheats)
  • Levels menu (Options -> Level Select)

Usage

Copy Doom-*.fw to your SD Card folder odroid/firmware and PRBOOM.WAD and DOOM.WAD to roms/doom. Power up the Odroid GO while holding B. Then flash Doom from the menu. You can add more than one WAD at a time, a prompt will be shown on power up.

To do / Known issues

  • Fix the random lags. It might be caused by SD card access on the shared bus.
  • Fix the memory allocation failures due to memory fragmentation (especially when switching levels)
  • Make it possible to delete savegames.
  • Add support for external DAC

Compilation

ESP-IDF version 4.0.1 or greater is required to compile the current code.
