Nobody has played it on Walnut yet, so it has no medal.
Installation
In Walnut Games, the desktop app: Install, then Add game files... and pick your copy of Doom II: the disc in the drive, an ISO, BIN/CUE or MDF image, an installer or a folder. The game data is not part of the package, and Walnut does not offer it.
What works: DOOM2.WAD from Doom II 1.9 or the original 1.666: a CD, an installed copy, Steam's common/Doom 2 folder or the GOG installer.
More ways (a terminal, game-data-packager on any Debian system, copying the files by hand): Guides.
Or from a terminal, from Walnut's apt repository:
sudo apt install dsda-doom
Known issues
- Nobody has played it through a session on Walnut yet, and it has not been tried with Doom II's own WAD.
- DSDA-Doom's MIDI music chops on the PS3: about 465 sound underruns a minute with the synthesizer on the SPEs (measured with Freedoom, not with this WAD).
