# HTPC Windows Games — Compat Status

Live status of 39 non-Steam Windows games added to Steam on Bazzite HTPC (`bazzite@192.168.1.86`). Tested 2026-05-22 after initial CompatToolMapping setup (Proton Experimental default, 7 older titles on Proton 8.0).

## Working ✅
- Fallout 4

- Red Alert 3
- Samurai Gunn (works but **gamepad not working**)
- GTA V (assumed; not retested)
- Cuphead (assumed)
- Plus other untested titles

## Broken — won't start

|---|---|---|---|---|---|
| Atomic Bomberman | 2875360586 | "instr at 0x00000000 referenced 0x7. Memory could not be read" | 1997 DOS-era game — likely needs DOSBox, not Proton | proton_8 | Wrap launcher with DOSBox (dosbox-staging via Steam Tinker Launch) |
| Brawlhalla | 2410005953 | Doesn't start | Adobe AIR / native installer flow needed | proton_experimental | Try proton_8; check if "BrawlhallaGame.exe" is wrong entry-point (should be `Brawlhalla.exe` launcher) |

|---|---|---|---|---|
| Discworld Noir | 2361018632 | Cyrillic shows as `?????` | Fixed `C:\Discworld Noir` symlink ✅; installed `corefonts` ❌ (still ?) | Set `LANG=ru_RU.UTF-8 %command%`; if no — `WINEDLLOVERRIDES="gdiplus=n,b"`; if no — install ttf-mscorefonts manually + register Cyrillic codepage in registry (`[HKCU\Software\Wine\Fonts\Replacements]`) |
| Doom 3 BFG | 3602815006 | White screen, audio plays | proton_10 ❌ | Try `PROTON_USE_WINED3D=1 %command%`; or proton_8; or `+set r_useOpenGL32 1` |

|---|---|---|---|
| Final Fantasy X HD | 2642741094 | Game in Japanese; saves missing | Set language in `Documents/SQUARE ENIX/...` config; copy save folder from `/run/media/bazzite/Windows/Users/<user>/Documents/SQUARE ENIX/` if present |

## Input / gamepad
- **Samurai Gunn**: gamepad not detected
- **Super Bomberman R2**: gamepad not detected
- **Metal Slug X**: launches via Neo-Geo emulator wrapper but speed is wrong and controls don't work
  - → check Steam Input "Force Off" → "Use Default" cycle, or `SDL_GAMECONTROLLER_ALLOW_STEAM_VIRTUAL_GAMEPAD=1`

## Duplicates — remove from Steam (already installed via real Steam)
- Human Fall Flat (3928445186) — remove shortcut + grid covers
- Shovel Knight (2526703384) — remove shortcut + grid covers

## Cover-art swaps (done 2026-05-22)
- Atomic Bomberman (was wrong "Bomberman 64" cover)
- Discworld Noir (was "Disco Elysium")
- Super Bomberman R2 (was Switch boxart)
- Final Fantasy VI (was "Final Fantasy III")
- Zelda: A Link to the Past (was "ALttP + Four Swords")
- Sunset Riders (was "Captain Commando"; also renamed shortcut)

## Infra notes
- `~/.steam/steam/userdata/147839491/config/shortcuts.vdf` — binary VDF; edit with Steam closed (`systemctl --user stop gamescope-session-plus@steam.service`)
- `~/.steam/steam/config/config.vdf` — text VDF; `CompatToolMapping` section controls per-AppID Proton
- `~/.local/share/Steam/steamapps/compatdata/<AppID>/pfx/` — Wine prefix for each shortcut
- `protontricks` (Flatpak) needs xvfb + flatpak filesystem permission to `~/.local/share/Steam`
- Background protontricks runs via `systemd-run --user --unit=<name>` (survives SSH disconnect)
