Are you using
PPCLibEMu? Try installing it if your not using it (read install info). Your ppc.library should be something like v46.xx instead of 0.9 in your medreport.
For the gfxaddress run Scout, select "expansions" and use the "boardaddress" of the second line there. It should read "$60000000" as seen on your medreport. PCIinfo for me gives false readings.
I'd try:
NoCache=NO
Emulation=NO
VoodooMem=26
Warp3D=Yes/NO (try both)
Force=1
Change ahi.device to 4.18, the newer one is slower and causes problems on classics. Can't see anything unusual in your S-S.
