My old Sega 8-bit hacking guide (Master System & Gamegear)
« on: January 20, 2015, 06:46:28 PM »
Back in the dim and distant past when I was hacking Gamegear and Master System Games via the Meka emulator, I wrote a guide on how I'd done it (using my basic Z80 knowledge). Earlier on tonight I found all my files and converted it into a PDF.

It's nothing special (the guide or the files that accompany it) but with the help of a mate who wrote a Game Genie code decrypting spreadsheet (the joys of VLOOKUP!), I merrily went a-hacking away.

I went back to the Z80 after years of doing Atari ST trainers and the same skills required were applicable across the different chipsets. If only I'd known that a bit more patience when I was a teenager, I could have been doing this kind of stuff when I had a ZX Spectrum.

There are two files, one is the guide with separate text files listing all the ones I managed and a sub-folder of those that 'got away' at the time.

File #1: The guide plus the example text files.

File #2: The Game Genie codes, plus my mate's spreadsheet and some other decrypting utilities that I'd found.

Just a piece of history from almost 15 years ago. These files used to be on one of my old websites which I'm too lazy to resurrect
