but as a fact it is NOT desigend in a common Context
and S3 Pro Savage GFX Card ....should be exchanged.. may be to an S3 Delta Chrome or something else actual GFX HW...
but thats the thing emulation is a bonus given to fast and good equipped PC
if someone complains over emu high PC requirements, he should by the console for erh. 70$(ebay or so)?
and then be happy and should not complain about hard work (done in their freetime!) of emu coders.
