Sega 8-bit

This page will contain my tutorial (from many, many years ago) that I wrote in the early days of the Sega 8-bit emulator, Meka.

I had a spreadsheet (written by a friend using Excel VLOOKUP tables) that would convert Action Replay codes into actual addresses in memory. Using the DZ80 tool, I would disassemble the Sega 8-Bit game via the ROM dump, then work out where the Action Replay code was tweaking the memory. I would convert this into a proper byte patch in memory which Meka could use to alter the game’s memory whilst it was running.
