MSYS2/mingw-w64 dropped Windows XP support, not just the toolchain environment but including native binaries produced by the GNU GCC compilers. The main culprit is winpthread library. The upstream targeted Window 7 APIs as minumum requirement. https://github.com/msys2/MINGW-packages/issues/5139# …

I use Linux. Compiling qemu 4.2 under Windows is a rather non-trivial task. Only for experienced people with full necessary toolchain installed. For those swears by Microsoft toolchain, then this may be true for them. Today, MSYS2/mingw-w64 provides similar Linux experience with the same GNU GCC …

If the file manager you used is a DJGPP DOS apps, then you may want to look at this. DJGPP faulty keyboard handler Pure DOS command prompt, real-mode only application should be fine. I do not have any keyboard issues with those.

Did your Debug freeze when trying to execute assembled code you just entered? Even if you were certain it shouldn't freeze the OS? I see I forgot to mention my version of DOSBox, it's 0.74-3. Managed to single-step a number of instructions. Everything seemed normal, no freeze no crash. I compiled …

I was able to run DEBUG.EXE from Win98SE DOS (7.10) and Microsoft CodeView 4 all with DOSBox internal DOS. For DEBUG.EXE all I need to do is to fake the DOS version reporting from DOSBox with "ver set 7 10". Microsoft CodeView was my favorite code tracer and debugger for 16-bit code before I got to …

True, but the function was always declared as BOOL BitBlt (...) in the SDK. In Windows NT 4.0, it also returns either 1 or 0. You are right. The SDK has never said a programmer can depend on the BitBlt() returned value to decide how many lines was blt'ed. Perhaps, some genius game hackers turned …

It definitely looks like Mech2 Mercenaries 1.00/1.05 PC for DOS/Windows. The fake "3Dfx" version (which is still Direct3D) has a grey CD cover. If my guess is correct, then yes you have the option to patch it for Direct3D hardware acceleration. Patch up to 1.06 to retain DOS/Windows version without …

You can probably check out zeck's OpenGL-based GlideWrapper084c in BoxedWine since it has a decent implementation of OpenGL pass-through. Zeck's GlideWrapper is also a fairly compatible Glide wrapper.

If you really mean Mechwarrior 2 Mercenaries(1996) , then you can patch it all the way to get Direct3D hardware acceleration on Win9x, which should work for Riva128/TNT/TNT2. If you mean Mechwarrior 2 31st, then the 3Dfx Glide version can be made to work through dgVoodoo1 with hardware supporting …

QEMU threaded its internal workloads very much. There is one UI main process, each CPU has its own thread, block I/O on its own thread, each screen has its own rendering thread and audio also on its own thread. So at minimum, there will be 1 process and 4 threads running. I think it depends on the …

Windows 98 does not officially support DirectX9. You can either play the game on WinXP~Win7 or replace the nGlide with dgVoodoo1 that supports DirectX7 backend on Win98. Since this is a GoG release, then it should able to run on modern Windows.
