OK, I am having a little problem with this here - how exactly is the speed determined. Hopefully not by the FPS figure shown when you exit MAME. The thing is what about auto frameskip. I always use this myself, and is great with games that my PC cannot quite manage 60FPS. For example, I can run Street Fighter Zero fine, with auto frameskip for the most part at 2-5 frameskip. Usually between screensthis takes a big hit, but quickly recovers. Super Sprint is the same only more so. The result of this though is an average FPS of around 30FPS. If anything, it's more of a disadvantage. Basically the average FPS figure shown on MAME's exit is not an accurate speed percentage.(posted 9450 days ago)My question is how exactly will the speed be determined to be under 90%? Also, many games will cause slowdown: a) during startup, ROM/RAM checks etc.., and b) between screens, fancy screen fades and palette changes. Which will knock down any average speed score.
Basically what I'm trying to say is that this will be a difficult one to prove.
