This change addresses a reproducible launch-state regression for Batman: Arkham Asylum GOTY (Steam app id 35140) in GameNative, and also adds DirectX preinstallation support required by this title's redistributables. Observed behaviour: - Fresh install/download could launch successfully on first run. - Exiting the game normally and relaunching it later could leave GameNative on a black screen. - The black screen was not an Android app crash. The actual game process (ShippingPC-BmGame.exe) was starting and then terminating, while Steam/coldclient container state could remain alive. Reproduction used during investigation: - Device: OnePlus OPD2415 - Android: 16 - Game: Batman: Arkham Asylum GOTY - Store: Steam - App id: 35140 Root cause: Batman was sensitive to stale state surviving between launches. Cleaning only the Steam coldclient marker improved the situation but was not sufficient by itself. Reliable recovery required clearing the stale launch artifacts that persisted across sessions: - ColdClientLoader.ini in the Steam prefix - STEAM_COLDCLIENT_USED marker in the game install directory - BmEngine.ini and BmGame.ini under the game's Documents config path - ShippingPC-BmGame.dxvk-cache in the container cache Changes included in this commit: - Add a Batman-specific Steam game fix for app id 35140 that clears the stale launch/config/cache files above before launch. - Register that fix in GameFixesRegistry so it is applied automatically for Batman. - Regenerate ColdClientLoader.ini more defensively by deleting stale coldclient launch state before writing a new ini. - Add DirectX preinstallation detection/execution through DXSETUP.exe and track it with a dedicated marker, because Batman's redistributables include legacy DirectX components that need to be installed for a clean first run. Why this matters: Without this cleanup, Batman can appear to fail randomly after a successful first boot, when the issue is actually deterministic stale launch state reuse. This makes the regression highly visible and user-facing because the game works once, then later relaunches degrade into a black screen. Validation: - assembleDebug completed successfully. - Verified on-device on the OnePlus OPD2415 / Android 16 test setup. - Confirmed successful cycle: launch game -> exit normally -> close app -> reopen app -> launch game again.

Quote DXSETUP paths and dedupe queued commands.
The command string is built without quoting the executable path, which can fail for redistributable paths containing spaces. Also, deduping avoids running the same installer twice when scan roots overlap.

I believe trying to install directx will fail on many proton versions and basically cause a stall. Have you tested the different proton versions? |
DirectX preinstallation was only observed as a possible factor in one failed first-run attempt and was not validated across a matrix of Proton versions. The relaunch black screen fix that was actually reproduced and verified on-device is the stale Batman/Steam launch-state cleanup, so this commit removes the broader DirectX preinstall change and keeps the PR narrowly scoped to the confirmed fix.

Good point. I had only validated that part on my device with proton-10.0-arm64ec-2, and I had not tested a proper matrix across different Proton versions. To be precise, the DirectX preinstall part only came up after one failed first-run attempt, and after that I had to redownload the game from scratch, so I do not consider that part properly verified. The part that was actually reproduced and confirmed on-device was the relaunch black screen fix itself, caused by stale Batman/Steam launch state between sessions. I’ve removed the DirectX preinstall part from the PR and kept only the narrower relaunch-state cleanup that was consistently reproducible and tested. Thank you for your reply : ) |
Remove the global stale coldclient reset from SteamUtils.writeColdClientIni(). The relaunch regression we reproduced and validated was specific to Batman: Arkham Asylum GOTY, and the PR already has a dedicated STEAM_35140 fix that clears the stale marker, stale ColdClientLoader.ini, and Batman-specific config/cache files before launch. Keeping the reset global would broaden the behavior for unrelated Steam titles without equivalent validation.

Fix DXVK cache target path under container.rootDir.
Line 29 currently targets <rootDir>/.cache/..., but container user cache is under /home/${ImageFs.USER}/.cache. This misses the intended stale cache file.

Add explicit logging when marker deletion fails.
If the marker exists and removeMarker(...) returns false, the code currently has no warning path, which makes cleanup failures harder to debug.

I scoped the stale coldclient cleanup down to the Batman-specific fix as well. The global reset in That keeps the PR focused on the confirmed Batman relaunch regression without changing launch-state handling for unrelated Steam titles. |

PR utkarshdalal#775 introduced ExeRunDir to fix save loading in New Star GP, whose exe lives in a subdirectory (release/NSGP.exe) and opens saves via a relative path from the game install root. Without ExeRunDir, ColdClient- Loader defaults the working directory to the exe's parent, so the save file was never found. However, hardcoding ExeRunDir to the game root broke games like Batman: Arkham Asylum GOTY (reverted in PR utkarshdalal#950), which declares workingdir: Binaries in its appinfo. For these games, the correct CWD is the subdirectory, not the root — and the previous empty ExeRunDir happened to work because ColdClientLoader defaulted to the exe's parent. The fix reads workingDir from the Steam launch config (LaunchInfo) and appends it to the game root for ExeRunDir when present, falling back to the game root when absent. This matches Steam's own behaviour across all cases observed in the wild. The INI content is extracted into generateColdClientIni() for testability, with unit tests covering the Batman and New Star GP cases and edge cases such as trailing slashes and forward-slash normalisation.

Hi @Misazam, I don't think the coldclient.ini deletion is really relevant here. It has nothing to do with the game. I think what most likely needs to be cleared is the cache file only - clearing the other inis will clear user settings. Please double check that just deleting the cache on every launch is sufficient. |

This change addresses a reproducible launch-state regression for Batman: Arkham Asylum GOTY (Steam app id 35140) in GameNative.
Observed behaviour:
Reproduction used during investigation:
Root cause:
Batman was sensitive to stale state surviving between launches. Cleaning only the Steam coldclient marker improved the situation but was not sufficient by itself. Reliable recovery required clearing the stale launch artifacts that persisted across sessions:
Changes in this PR:
Why this matters:
Without this cleanup, Batman can appear to fail randomly after a successful first boot, when the issue is actually deterministic stale launch state reuse. This makes the regression highly visible and user-facing because the game works once, then later relaunches degrade into a black screen.
Validation:
Note:
A broader DirectX preinstall change was initially included during investigation, but it was not validated across multiple Proton versions and has been removed from this PR.
