There's another post somewhere on these boards that has workarounds that apparently fix the bug when using dgvoodoo. I don't know if either of them would work with GliDOS as Audrey is currently having a holiday at the Sony Repair Centre in France.
It was a user called Dornkirk that came up with this so all credit goes to him, I'm just quoting his post as the original thread is HUGE!
After some testing I found two workarounds which seem to prevent the game from crashing in 'Fridge Racer'
For both workarounds you need to decrypt carmageddons .TXT files using the 'IWANTTOFIDDLE' cheat.
Workaround 1:
Open the file 'ICE.TXT', search for the string 'START OF PEDESTRIAN STUFF', delete all but the first ped and change the number of peds to 1. You will lose all peds, barrels and mines, but the posts will break if you hit them hard enough.
Workaround 2:
Open the file 'ICE.TXT', search for the string 'Non CarObjects', delete the line 'CONE.TXT' and set the number of non car objects to 3. You will keep all peds, barrels and mines, but the posts will be rocksolid.
Personally I'd go for the second one as I don't see the point of Carmageddon without pedestrians!
I'll try it out when I get Audrey back and report back unless someone else wants to try it out.
