Thanks, I hope it resolves the digit problem. I don't think the SM5xx emulation is 100% accurate yet though, the biggest proof at the moment is G&W Mickey & Donald locking up randomly, it's a standard SM510. I'm also not sure if gameplay is right in TMNT and Contra(both SM511) where the timing seems very erratic.
