WIP9 of v4 of SNES Speedy Gonzales "any%".
I switched to v1.1 ROM, which causes loss of 1 frame on startup. On the other hand, I'm 637 frames ahead (including that one lost frame) at start of 4-2.
Saved 105 frames in 4-1 due to better luck with those swings, some optimization and some lag reduction.
