Something is wonky with the F5 option on the 64-bit version of the trainer when playing the Steam version of the game. If you enable it, nothing happens at first. But if it is enabled and you load a game/resume a game/restart a level, then it goes a bit haywire. You get "infinite Ki", no increased damage whatsoever (at least according to the numbers I am seeing in the fly text in-game), super speed, jump height is cut in half, and Lo-Wang is all wobbly. Oh, and the icing on the cake, is you eventually die after about 10 minutes or so unless you don't run anywhere because with the sort of speed I mentioned, you're bound to fling yourself through the geometry at some point (even infinite health option doesn't prevent this death).
It was good for a laugh, and I really liked the infinite Ki (which is more useful than infinite skill points tbh, one is limited, the other is only limited by how much damage you can combo onto enemies to push your Karma). I think they might have changed the float value offsets again XD
Edit: The infinite KI doesn't stick around if you disable F5 and reset/reload to get rid of the rest of the wonky effects, however. This of course means that it wiped out any points you had assigned. Still good for a laugh though.
