Thanks for the feedback! I've uploaded a new version with a fix for the issues :)

Cool, noticed - now that I had sound on - that it lags a bit, especially the high frequency beep when hitting stuff is a frame too late and doesn't come directly as you hit.
Big bug: Score is missing a digit, it's supposed to have four digits, when I passed 999 it went to 001 instead of 1001.
Not to bad emulation, got 1827 on the real thing the other day.
