Nice WIP, zggzdydp! Stage 2 boss fight may be better than mine! You can improve your run though, see my old WIP (TestRun, maybe).

Though Lottery いー0 glitch works with J version only, any other glitches should also work with USA version.
And yes, Snes9x 1.43 desyncs often with the game. I don't know if 1.51 (improvement) has a problem like that.
Edit: Hex-editing would help you when it desyncd :)
Note: I still wish the run of the game would be finished with J version ;)
Current Watch for Ganbare Goemon J V1.2
