Примечание: требуется авторизация в VK Play через лаунчер. VK Play использует `mycomgames://` URL-схему. Atomic Heart официально совместим со Steam Deck/Proton (подтверждено VK Play).
## Mapped to GE-Proton10-34 but **still broken** (need further investigation)
These were swapped to GE-Proton in hopes its bundled VC++/d3dcompiler/dotnet/dxvk-async would fix them. Same symptoms as before — GE-Proton may be reusing the existing prefix's wine state. **Next:** consider deleting `pfx/` to force GE-Proton to regenerate cleanly.

## VDF Incident — 2026-05-27
### Что произошло
При попытке добавить VK GameCenter и Atomic Heart VK в shortcuts.vdf через Python vdf.binary_load/dump на работающем Steam, Steam переписал VDF при старте, создав 110 пустых записей-заглушек. Все бэкапы (bak, bak-launch, bak2-6, clean, timestamped) также оказались пустыми — они были сделаны уже после того как Steam испортил файл.
### Как восстановили
Обнаружено что `shortcuts.vdf.bak-eagle` (23 мая, 50720 байт) содержит 106 живых шорткатов. Проблема с `vdf.binary_loads` — он ищет ключи с точным регистром: `AppName`, а не `appname`.
1. Остановлен Steam (`systemctl --user stop gamescope-session-plus@steam.service`)
2. Считан bak-eagle, добавлены записи VK GameCenter (index 106) и Atomic Heart VK (index 107)
3. AppID в shortcuts.vdf — signed int32; в config.vdf CompatToolMapping добавлены как unsigned uint32
4. После записи обнаружено несоответствие appid — в config.vdf уже были entries с другими appid от предыдущих попыток
5. Перегенерация shortcuts.vdf с appid, совпадающими с config.vdf: VK GameCenter = `-555655402`, Atomic Heart VK = `-475792602`
6. Удалены дублирующиеся unsigned записи из config.vdf
7. Создан бэкап `shortcuts.vdf.whale-restored-2026-05-27`
### Восстановленный backups
- `shortcuts.vdf.bak-eagle` — 106 entries, чистый, не тронут ✅
- `shortcuts.vdf.whale-restored-2026-05-27` — 108 entries (106 старых + VK GameCenter + Atomic Heart VK) ✅
### Уроки
- Редактировать shortcuts.vdf ТОЛЬКО при остановленном Steam
- vdf.binary_loads: ключи с точным регистром (`AppName`, `Exe`, а не `appname`, `exe`)
- signed appid в shortcuts.vdf → unsigned (signed & 0xFFFFFFFF) в CompatToolMapping config.vdf
- Перед добавлением новой пары шорткат+Proton — проверить, нет ли уже CompatToolMapping с нужным appid в config.vdf
- Делать бэкап ДО любых изменений, а не после
## Fixes done (filesystem / config / cover-art)
- Cover art swapped: Atomic Bomberman, Discworld Noir, SBR2, FFVI, ALttP, Sunset Riders
- "Captain Commando" Steam shortcut renamed → "Sunset Riders"
- `CompatToolMapping` for all 39 AppIDs in `config.vdf`
- **GE-Proton10-34**: Brawlhalla, Castle Crashers, Worms WMD, Worms WP, Duck Game, Rayman Origins, Doom 3 BFG (7 games)
- **Proton 8.0**: Atomic Bomberman, Discworld Noir, Metal Slug X, Soldat, Red Alert 3, Split Second (6 games)
- `CompatToolMapping` for all AppIDs in `config.vdf`:
- **GE-Proton10-34**: Brawlhalla, Castle Crashers, Worms WMD, Worms WP, Duck Game, Rayman Origins, VK GameCenter, Atomic Heart VK, insaneramzes Atomic Heart
- **Proton 8.0**: Atomic Bomberman, Discworld Noir, Metal Slug X, Soldat, Red Alert 3, Split Second
- **Luxtorpeda**: Doom 3 BFG
- **Proton Experimental**: ~24 remaining games
- Rayman Legends: Ubisoft Connect copied from Windows partition into prefix + registry `HKLM\Software\Wow6432Node\Ubisoft\Launcher\InstallDir`
- Discworld Noir:
- `C:\Discworld Noir` symlink → game folder ✅
- LaunchOpt `HOST_LANG=ru_RU.UTF-8 HOST_LC_ALL=ru_RU.UTF-8 LANG=ru_RU.UTF-8 LC_ALL=ru_RU.UTF-8 %command%` ✅ (Cyrillic now renders)
- `corefonts` installed via protontricks ✅
- 69 missing files copied from `/Data/downloads/zatmenie v2 [torrents.ru]/cd2/` to game's cd2 ✅
- Drive D: → cd2 folder, marked as CD-ROM in `[Software\Wine\Drives]`
- Doom 3 BFG moved to Luxtorpeda → rbdoom-3-bfg (native Linux engine, 2026-05-27)
- Rayman Legends: Ubisoft Connect copied from Windows partition into prefix + registry
- Discworld Noir fixes (symlink, Cyrillic locale, missing files, drive D:)
- FFX HD: `GameSetting.ini` replaced with English+HD version
- VC++ runtime DLLs + `d3dcompiler_43/47` copied into 6 prefixes from Windows partition
- Duck Game prefix: XNA 4.0 framework dir copied from Windows
- Atomic Bomberman prefix: `Version=win98` + virtual desktop 640×480 + WineBus controller mapping disabled
- Atomic Bomberman prefix: `Version=win98` + virtual desktop 640×480 + WineBus disabled
- GE-Proton10-34 installed to `~/.steam/steam/compatibilitytools.d/`
## Source assets discovered on Windows partition
- `/run/media/bazzite/Windows/Program Files (x86)/Ubisoft/ubisoft game launcher/` (595 MB) — used for Rayman Legends prefix
- `/run/media/bazzite/Windows/Program Files (x86)/Ubisoft/ubisoft game launcher/` (595 MB)
- `/run/media/bazzite/Windows/Windows/System32/` and `SysWOW64/` — VC++ runtime, d3dcompiler, xinput DLLs
- `/run/media/bazzite/Windows/Program Files (x86)/Microsoft XNA/` — XNA 4.0 Framework
- `/run/media/bazzite/Windows/Microsoft.NET/Framework64/v4.0.30319/` — .NET 4.0
- `/run/media/bazzite/Data/downloads/zatmenie v2 [torrents.ru]/` — original Discworld Noir Russian 2-CD source (cd1, cd2, dwnrus_1_v2.nrg, dwnrus_2.nrg)
- `/run/media/bazzite/Data/downloads/zatmenie v2 [torrents.ru]/` — Discworld Noir source (cd1, cd2, .nrg images)
- `/run/media/bazzite/Windows/Users/mallexxx/documents/square enix/...` — FFX gamesetting.ini
## Open questions / next steps
1. Try **deleting `pfx/` folders** for the still-broken GE-Proton games (Brawlhalla, Castle Crashers, Worms WMD/WP, Duck Game) to force fresh prefix creation with GE-Proton's bundled runtimes
2. Doom 3 BFG: investigate gamescope+OpenGL interaction (the game uses OpenGL natively, not D3D; white screen suggests gamescope/X11 swap issue, not DXVK)
3. Atomic Bomberman: create a separate 32-bit `WINEARCH=win32` prefix outside Proton, install game there, wrap as launcher script
4. Discworld Noir: if drive D: → cd2 doesn't satisfy CD check, try cd1 or mount one of the `.nrg` images
5. Metro Exodus: ask user if OK to use Goldberg Steam emulator

5. **Atomic Heart VK:** test VK Play авторизацию через Proton, при необходимости — protontricks vcrun2019
6. **Doom 3 BFG:** test с Luxtorpeda → rbdoom-3-bfg (должно работать с нативным OpenGL)
## Lessons learned / Infra notes
- `shortcuts.vdf` is binary VDF; edit only with Steam closed (`systemctl --user stop gamescope-session-plus@steam.service`)
- `shortcuts.vdf` is binary VDF; edit only with Steam closed
- `config.vdf` is text VDF; `CompatToolMapping` block controls per-AppID Proton
- Steam reads both vdfs on startup, writes back from in-memory state on exit → any edit while Steam running will be lost
- Steam reads both vdfs on startup, writes back from in-memory state on exit
- `protontricks` (Flatpak) needs `flatpak override --user --filesystem=/var/home/bazzite/.local/share/Steam`
- Parallel protontricks runs on same Proton version **conflict** on the shared bin cache — must sequence
- `xvfb-run protontricks <verb>` — MS-redist EXE installers (dotnet40, VC_redist) **hang on invisible button click**. Workaround: copy DLLs from Windows partition + `WINEDLLOVERRIDES="dll1,dll2=n,b" %command%`
- For Cyrillic/locale: Proton needs `HOST_LANG` / `HOST_LC_ALL` env vars to propagate locale into prefix
- Parallel protontricks runs on same Proton version **conflict**
- `xvfb-run protontricks <verb>` — MS-redist EXE installers **hang on invisible button click**. Workaround: copy DLLs from Windows partition
- For Cyrillic/locale: Proton needs `HOST_LANG` / `HOST_LC_ALL` env vars
- Background jobs that survive SSH disconnect: `systemd-run --user --unit=<name>`
- **GE-Proton install:** download tar.gz from `github.com/GloriousEggroll/proton-ge-custom/releases/latest`, extract into `~/.steam/steam/compatibilitytools.d/`, restart Steam — tool name in `CompatToolMapping` matches the extracted directory name (e.g. `GE-Proton10-34`)
- GE-Proton install: extract tar.gz into `~/.steam/steam/compatibilitytools.d/`
- `vdf.binary_loads` key names are case-sensitive: `AppName`, not `appname`
- signed appid in shortcuts.vdf ↔ unsigned in config.vdf CompatToolMapping
