I can increase the limit (eg: 10000) or allow users to set their own limits since this affects the size of the bar if that would make it more useful, but potentially less safe. This was because anything faster and I noticed games might crash from time to time. I set an arbitrary limit of 500 FPS for the tool. Also, it really runs smoooth, no doubt about that, the lag on the selection screen and the mining rocks is gone

The thing is, some details like the speed at which the HP bar comes down on a foe, or that fading animatin of certain foes (i.e. I haven't tried in reborn but 2+2=speed so it should work as well. Doesn't really 'speeeeeeeeed' the game beyond boundaries but, um, if you have used the 'fast forward' option of a GBA emulator, it comes to be more or less that, at least on Insurgence, where I just tried it a few minutes ago.
