Carmageddon (1997) freezes a few seconds after race starts

Postby msteel » Sat 22 Jul, 2017 2:14 am

Hello , I have been trying to get Caramageddon MaxPack to run on PCem with minimal success. The game loads fine however when the race starts the game will freeze shortly after. I have tried the released version as well as the latest dev build with the same result.

Host CPU i7-6700k
Tested running game on Windows 98 and MS dos 6.22
both 3dfx and software rendered versions.

If the game is run on windows 98 (dos) I am able to ALT TAB back to the desktop so PCem does not appear to be crashing just the game itself.

I'd like to help resolve this, I believe PCem to be the best way to relive classic OS's and Games short of playing them on the actual hardware they were made for.

Thanks,
Chris.

REALLY REALLY LATE EDIT: The Splat Pack's Windows 95 engine doesn't freeze.

Does anyone have a suggestion for a process monitor for windows 98 to see what's actually being requested from the OS when the game crashes?

Process Explorer 11.11 should work ;)

No luck, that program only shows processes running under the windows kernel. DOS games don't register at all ::

This is looking like some horrible floating point issue. Might take a while...

Carmageddon used to work for me, but it's been a while since I tried it.

Update, carmageddon now crashes back to a desktop in windows 98 immediately when the race starts rather then freezing at random.
