Here's my MedConfig report.
Things i noticed:
* you have older Mediator files, update them! (but only use voodoo.card version 4.23)
* i have also MMU Warp 3D -mediator files installed (don't know if it makes any difference, MMU is set to NO)
* i'm using Warp.library 5.1, yours is 4.0
* your gfxaddress is set to $200000, mine is $80000000
* you have older rtg.library
* you don't have ppclibemu installed (according to startup-sequence), get it
here.
Hope this helps :-).
EDIT: are you using G-Rex 68040/68060 -libraries? If so, remove and replace with ones found
here. The Gears-demo runs fine here.
Btw. anyone know what really is the difference between 46.7 and 46.15 68060-libraries?
