Hello everyone,
After testing, it has been found that the minimum requirements to launch StarCraft Remastered are having the following three files: .build.info, ClientSdk.dll, and StarCraft.exe, along with the Data folder in the game's root directory. The version number in .build.info must match the data version in the Data folder, and the versions of ClientSdk.dll and StarCraft.exe must also be consistent.
I'm not sure whether Blizzard developers placed the AI logic in the Data folder or within the main executable file StarCraft.exe, but I suspect it is most likely in StarCraft.exe. Therefore, if you still have any version of StarCraft.exe and its corresponding ClientSdk.dll from versions 1.23.0.6342 to 1.23.5.8607, please send them to my email at rym1020@qq.com. This might help resolve the replay playback error issue.
Best regards.
