Hi, Does this series exactly fix the issue and make those games playable? AFAIU, it is AntiCheatExpert requires these functions, and sometimes just implementing a couple of functions is far from making the game playable; what is worse, maybe some other game will become unplayable because the exposing of these functions guides them to another code path (e.g. it goes further in the anti-cheat detection) that has issues on Wine. btw, Arknights: Endfield, which ships AntiCheatExpert, depends on KeAcquireGuardedMutex() too. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/2044#note_127675

[PATCH 0/1] MR9486: windowscodecs: correct GIF LZW compression initialization
by Jiajin Cui (＠jin-king1) 22 Jan '26

22 Jan '26

The GIF LZW compression algorithm was incorrectly initializing the code size to 8 bits regardless of the actual color depth. This caused issues with images that have fewer colors requiring smaller initial code sizes. The fix calculates the proper initial code size based on the actual number of colors in the image, using the formula: minimum code size = max(2, ceil(log2(color_count))). This ensures proper compression for images with small color palettes and maintains compatibility with GIF decoders that expect correct LZW initialization parameters.

[PATCH v14 0/3] MR7539: combase : clsid_from_string_reg() add read of CurVer key value.
by Maotong Zhang (＠xiaotong) 22 Jan '26

22 Jan '26

If the read ProgID only has a CurVer key and no CLSID key, it will directly return CO_E_CCLASSSTRING, causing the program to fail to continue running. Add the key value for finding CurVer. -- v14: combase:clsid_from_string_reg() add read of CurVer key value. ole32:Do not zero out when not a CLSID ole32/tests:Remove now succeeding todo_wine https://gitlab.winehq.org/wine/wine/-/merge_requests/7539
