Galaxian (NES) has a hidden "sound test", which is very... convulted to access (it requires resetting the system over 45 times, and another 45 to change tracks) as well as holding the A+B button on P2 and all kinds of other shit.
If you didn't know any better, you might assume it's just some glitch.
Soon after I first discovered it, I fired up FCEUX and created a disassembly of it, changing things, removing dead code, and so on and so forth. That's been going on for a few days, on and off (mostly off).
This is my first adventure into 6502 outside of changing INC to DEC (cough).
ROM
Everything Galaxian-related aside from a majority of the code and the music has been stripped out or changed, and the music isn't original anyway, so...
I plan on working on this some more. Maybe turning it into some sort of beginner's music playtoy or something
Use: Reset changes tracks. That's about it really. The numbers should be fairly self explanatory if look closely enough.
