This is coming along well! Tested it on real hardware (Well, MiSTer FPGA is closer than traditional emulation at least) and there seems to be some graphical artifacts. Otherwise, things seem about functional!

ahh! Cool to see it on a CRT. I think I know why it's so glitchy at the start, cause it doesn't clear the screen.
I consider FPGA emulation, but MIsTer is close enough, and this game isn't doing anything fancy (can't imagine what the Everdrive does to circumvent lockout, unless this was already reverse engineered)
This made my day, thanks! ^o^
