Welcome to
The Master System / Game Gear Sonic Hacking Guides !

 

Have your emulators and hex editors ready, I'm bringing you infos on how to hack the SMS/GG Sonic games ! Currently, there is only the S1 Hacking Guide, for both SMS and GG. I am also working on Sonic 2, Sonic Chaos / Sonic & Tails, Sonic Triple Troubles and Sonic Blast. The Sonic 2 Hacking Guide comming soon !

So, what will you need to hack these games ? As always... An emulator and an hex editor ! I recommend you use MEKA. If someone knows a better emulator, tell me. Then, simply open your ROM with the hex editor. If you need help with the hex editor... Er... I will make a page with explanations on how to use an hex editor.

As you noticed, all guides were updated. In fact, they mainly contain corrections. However, the informations on the Art compression format was incomplete, so, I updated it.
