V23 Add writing of N64 repro (first draft, super slow)
Takes ~1 hour or so for a 64MB rom file since I have not yet implemented the roms 16 word write buffer and instead write only one word at a time. This is the repro I used: https://www.aliexpress.com/item/N64-Game-Resident-Evil-2-Nintendo-Video-Game-Cartridge-Console-Card-English-Language-US-Version/32788522464.html
