Installation

Put “prboom_v2.5.0_funkey-s.opk” in your OPK folder. You can launch it either through GMenu2X or RetroFE if you have installed Drum78’s Custom OS.

You can also grab the core alone (“prboom_libretro.so”) if you are comfortable with how to use it with your frontend.

Create a folder for each IWAD and put the file in there (“doom.wad” in “Doom”, “doom2.wad” in “Doom2” for instance, beware lower case is mandatory here!) and put your mods in the right IWAD folder. Then pick the WAD you want to launch with the file browser. Example of file structure:

PrBoom/
├── Doom/
│ ├── doom.wad
│ ├── mod1.wad
│ ├── mod2.wad
…
├── Doom2/
│ ├── doom2.wad
│ ├── mod1.wad
│ ├── mod2.wad
…
