mods are supported (yes, Brutal Doom as well) and should be placed in the gzdoom/pwads folder because the launcher only scans that folder.you can technically place the game into any folder, as long as the gzdoom folder is next to gzdoom_launcher.nro.GZDoom (especially some more complex mods) may require more RAM than is available in applet mode, so better use another title instead of the Album for HBMenu override, or use NSP HBMenu.This is partially because there's no JIT compilation for the scripts on the Switch.
You can start GZDoom by itself, but it will default to the last played IWAD (or the one it finds in the folder). To run, start GZDoom Launcher from HBMenu. For the complete list of what GZDoom supports, see the wiki. To install, unzip the attached ZIP file into the switch folder on your SD card, then place at least one supported IWAD (eg doom2.wad) into gzdoom/iwads/.
