Doom 2D is an old Russian Doom fangame, originally made for DOS in 1996 by Prikol Software.
It was ported to SDL in 2011 by Rembo. This is a port of that SDL port to Nintendo 3DS/libctru.
You should have the latest devkitARM and libctru installed and in your PATH.
make builds ctrd2d.elf and ctrd2d.3dsx.
make cia builds ctrd2d.cia.
If you have a way to install CIAs, build and install the CIA. If you only have the Homebrew Launcher, build the 3DSX and copy it to sdmc:/3ds/.
Then, copy the gamedata/ctrd2d folder to sdmc:/3ds/.
If you've installed the CIA, just launch the title; if you're using HBL, run it and Doom 2D should be in the menu.
Default controls:
- D-Pad: movement/aiming
- A: jump
- B: shoot
- Y: use
- START: menu
- L/R: change weapon; Y/N in menu prompts
If it crashes for whatever reason, it should freeze for a few seconds, allowing you to read the console.
- Music
- Some way to specify command line args or a config menu
- Faster graphics (should probably write a hardware renderer or something)
- NDSP sound (apparently CSND is deprecated?)
- Better timing/FPS cap
- Strafe button
