Important Note: These disassemblies will take a lot of time to complete, and they probably will never be complete, these are mainly here for research purposes. If you'd like to look into this disassembly, go here. I've also heard that there is two compression formats in Sonic Spinball, those being referred to as C1 (which is already cracked by drx) and C2 (not yet cracked). Yet again, huge thanks to ValleyBell and their GEMS tools, as the drivers are fully split and disassembled now. Majority of the non-disassembled code is hard-coded in C, which will be fun to disassemble. Most of what I disassembled in IDA Pro is mainly code pointing towards text and pausing the game, as well as some other routines I will look into later. I am making a disassembly of my own, which is going to disassemble each version of the game. First of all, the disassembly on Sonic Retro is very outdated, and I don't recommend using it as it wasn't disassembled properly as stated in the readme. Now onto the content that is non-prototype.

Will let you make lots of changes to the game, and will patch those changes into your ROM. Huge thanks goes out to ValleyBell and their GEMS tools, their tools are amazing! While using their tools, I got to find that there are actually quite a few sounds and songs in this prototype that were never properly documented, such as the incomplete version of The Machine (which is ID 00 in GEMS). This is a ROM editor for Sonic Spinball (Genesis/Mega Drive). ![]() This screen is located at 0x103400 in the ROM, and at 0x120000 is the start of 8kb EPROMs from a July Prototype of Sub-Terrania dumped by FAIRLIGHT. So first off, inside the Sonic Spinball August 1993 Prototype contains a screen from the group PREMIERE from the old BBS scene group, and inside of that it says that the prototype was supplied by Winston (who seems to have gotten quite a bit of the Sonic Prototypes from the BBS back in the early 1990s).

I'll highlight the most important finds first. Sonic The Hedgehog Spinball (Alt 1) ROM download is available to play for Sega Genesis. I've decided to take a look at Sonic Spinball and document anything I can find. I've noticed that not a lot of people talk about Sonic Spinball, and barely any of it has been properly documented either.
