PCem

Did anyone successfully try to launch ANY voodoo game with the new (ver 11.0) release? Quake 2, Forsaken, and everything that worked with 10.1 crashes with the new version. Am I doing something wrong?

Try disabling the Voodoo recompiler.

Also, please provide your pcem.cfg file.

Is it PCem crashing, or the games crashing?

I tried disabling the voodoo recompiler to no avail I will post the CFG file later when I get home

Same here, with and without Voodoo recompiler.
Win98SE + latest 3dfx reference driver(5/1999) + DX7.0a

Even starting dxdiag crashes PCem.

Okay, looks like I screwed up and the Voodoo recompiler in current v11 binary doesn't work when Data Execution Protection is enabled. I'll put together a fixed binary, but I'm not sure why this should also crash when the recompiler is disabled...

Okay, I've replaced the V11 Windows download. Can you try it and let me know if it works?

Unfortunately not for me, with both Voodoo recompiler states.
Host: Win10 Pro x64 recent patchlevel. DEP enabled for essential Windows programs and services only.

Maybe you should wait for omarsis81 reply.

If you would pn me your debug build I could send logs and dumps. However I might as will build one tomorrow myself if needed.

From Windows event log:
Exception code: 0xc0000005 (figures)
Error offset: 0x00150223

Unfortunately it doesn't work for me either.
I suspected it could be an issue with nVidia cards, so I switched to Intel HD, but it didn't work also.
My host OS is Windows 8.1. Maybe that's the cause?

If it helps, here is Windows 8.1 crash error:

Okay, think I know what this is (Windows crash error is actually useful!). I've replaced the download again. Third time lucky?

Yup! Very lucky indeed! It works now! What was it? A million thanks!

Curious as well. Wasn't clear to me why it would crash without DEP and without recompiler.
MSYS2 build from current repo works fine btw. It's noticably larger than your binary, though (3.5 MB).

Only change is that I rebuilt it with -mstackrealign. Technically it's my fault for forgetting that flag, but I prefer to blame whichever Intel designer decided that SSE2 wouldn't support unaligned accesses.

Oh, yes now I see it. Your repository Makefile.mingw includes -mstackrealign. Makefile.am doesn't for CPU_I386. I was using Makefile.mingw with MSYS2.

If you want to blame someone it better be GCC designers for not implying -mstackrealign with -msse2
It's known that SSE2 access to unaligned memory areas can at least cause a lot of time penalty.

I believe Intel has addressed alignment related issues in SSE3.

Well I tried but it didn't do anything for Lego Creator to use the Voodoo cards on Hardware.

I know Omarsis81 has been helping to get Lego creator to have better speed on Windows 95 on PCem and I haven't gotten through with the problem but...

I tried all of the Mach64 GX drivers that Omarsis81 gave me to use for the 2D card but nothing is working for me, to get Voodoo working with "Lego creator." I tried all of the content in each folder of the "Mach64 GX" folder of where it's contained but all of the drivers don't work. There must be something that I did wrong.

So Omarsis if you are seeing this can you see what your PCem v11 configuration, the directx version you are using and how you installed your Mach64 gx drivers and Voodoo 1 3.01.00 drivers on your Win9x.

Can this fixed binary be added to the linux download too please as it crashes on linux too
