Had to patch lots of values instead of just code since it loads speed constants from files instead of setting them in the code, but whatever since all of those mh games are bothersome anyway.

Tested even less than 2nd G, so I might modify it in the future. Minor stuff likely will always be a bit faster, but gameplay related stuff should be fine.

Awesome work! I tried your code and the game does indeed run at 60FPS now with it enabled. I haven't noticed any gameplay breaking bugs other than the stamina bar in demon mode draining faster than it should be just as someone else pointed out earlier, but other than that the game appears to be running solid. If I find anything else, I'll make a post about it.
