@Agozer Good Idea, generally. Problem is - my PC is currently broken, so i am only able to use the one of my dad, which isn't that fast. The funny thing is that Kawaks runs on Top Speed (except the CPS2 & CPS1-Roms, which seem to need more Processorpower), while Nebula runs very sluggish. @Xeon Okay, thanks. So i'll look for another romfile to get the valid p-roms. Thanks for your help and your patience. I don't know many boards where i wouldn't have been flamed for my total lack of experience
