i don't think the F10 key is dangerous in terms of cheating? or for playbackability (using frameskip or not to record doesn't appear to make a difference in playing back only when playing back sometimes fs=0 is needed), but the issue is it's not those; it's that F10 isn't a true arcade experience. weather or not people get bored/impatient waiting for things to happen (levels to clear, roms to load); there wasn't an F10 key in the arcades. i personally don't mind it as long as the recording will playback at normal speed. But i believe recordings have been dqed in tournaments for using F10.(posted 8570 days ago)
