Cheat codes for Sonic 2 on Sega
Edit: The codes are entered in the sound test screen, then you gotta restart the system via the controller by pressing Start, then hold the A button. It's timed though, you gotta hit all the sound test samples in pretty quick for the cheats to work.
I guess my lack of console culture shows. How did you even enter characters on that thing?
Damn, this bro went the slow incremental method, I think button C jumped through the numbers way faster..

I'm glad pc cheat codes were more accessible than that. Even though it doesn't make for such an interesting demo.
The game has a seemingly random 'Sound Test' option, which brings up a menu where you can test every single sound effect in the game. The sound effects are addressed in hexadecimal.
I think the main buttons are A and C, one increments the least significant digit, the other increments the most significant digit.
Its kinda hard to explain much beyond that, but I'll dig around and see if I can find a tutorial on YT..
