To apply Sierra's patch: 1) Restore original .exe from CD 2) Apply Sierra's patch 3) Apply my patch, it will fail on patching the executable, but as long as the RUN386.EXE from my patch is correctly in place, it still works. DETACHES_PROCESS flag is present then, but RUN386.EXE is not a DOS process, it is a Win32 process launching a DOS process as subprocess, so it's not a big deal that patching PCHESS.EXE fails. I cannot patch the PCHESS.EXE from Sierra's PCHESS98 patch, because PUSH 8 instruction...

Tried PCHESS98 patch in Win98, it doesn't fix your savegame-issue, so I guess Save works as it works by design (you can change main line to last move anyway in windowthat contains all moves and it also seems to be by design that a saved game cannot be continued against the opponent, it just saves the move history). Anyway, regarding PCHESS98 patch: My Patcher fails for byte pattern patch for CreateProcess call, but it's not a big problem, as CreateProcess flags in patched version changed so that...

Not related to patch, same behaviour under plain Win98.

Btw.: In case setup.exe crashes for you, I now updated NTVDMx64 to fix this issue.

Updated patcher to now also patch PowerChess 98 executable, runs fine on Windows 11

Tested Win11 loader on Win10, also works, so should also work with SecureBoot enabled with most recent ntvdmx64 which offers this possibility of installation on a system with Secure Boot enabled.

I don't quite understand, what do you mean that I should check?
