+## ROM Symlinks (Data partition → EmuDeck)
+
+Emulators expect ROMs at `~/Emulation/roms/<system>/`. Symlinks from
+the Data partition (`/run/media/bazzite/Data/`):
+
+```bash
+ln -s "/run/media/bazzite/Data/n64 roms"     ~/Emulation/roms/n64
+ln -s "/run/media/bazzite/Data/snes roms"    ~/Emulation/roms/snes
+ln -s "/run/media/bazzite/Data/gba roms"     ~/Emulation/roms/gba
+ln -s "/run/media/bazzite/Data/3ds roms"     ~/Emulation/roms/3ds
+ln -s "/run/media/bazzite/Data/ps2 roms"     ~/Emulation/roms/ps2
+ln -s "/run/media/bazzite/Data/dolphin roms" ~/Emulation/roms/wii
+ln -s "/run/media/bazzite/Data/cemu roms"    ~/Emulation/roms/wiiu
+ln -s "/run/media/bazzite/Data/mame roms"    ~/Emulation/roms/mame
+ln -s "/run/media/bazzite/Data/sega roms"    ~/Emulation/roms/genesis
+ln -s "/run/media/bazzite/Data/nes"          ~/Emulation/roms/nes
+```
+
+After symlinking, run **Steam ROM Manager** (EmuDeck) from Desktop Mode
+to import ROMs into Steam with cover art.
+
+## Non-Steam Windows Games
+
+`/run/media/bazzite/Data/games/` — 38 pre-installed games (Bayonetta,
+Cuphead, GTA V, Witcher 3, etc.). Add as Non-Steam games with
+Proton Experimental.
+
+`/run/media/bazzite/Data/steam/steamapps/common/` — already-Steam games
+(Gang Beasts, Shovel Knight, etc.). Add as a second Steam library path.
