Super Metroid on startup dumps its SRAM to RAM, then overwrites all SRAM, then does a checksum on SRAM, and only copies the RAM back to SRAM if it passes the check.
this is supposed to catch pirated games.
if you turn your console off while it's starting up it could interrupt the check and you could lose all your data

i know this because i disassembled the boot code

i reversed engineered the Super Metroid sound driver and made code to rip songs and instruments off the ROM. moreover, i located all the music packs. i then edited in my own "Fuck!" sound effect and pointed lots of SFX to that sample. the end result is that using the blaster, sommersaulting, etc. make the game say fuck a bunch.

while some of my notes have been lost to time, i think i still have a good portion of this project. anyone interested?
