Just wondering here, is it possible to hack Sonic 1 for the Game Gear or MS?

The infrequency of hacks of any 8 bit Sonic game is lacking, and it looks a lot easier than it would be to hack through than, say, Sonic 2, which has been done many times in earlier years.

It doesn't sound practical, I know, but it would be able to open up some more possibilities if there was some way to crack the game open.

Indeed it's very possible, I suggest that you check out the SCHG for Sonic 1 8-bit to get a feel of how the level layout is set up. However there are no hacking utilities for this game, making it somewhat difficult to modify fully if you don't know what you're doing. I have made a disassembly of the game though it's very incomplete and I made it when I was just teaching myself z80 asm so it probably won't be too helpful... If you really want to hack the 8-bit games I suggest you check out Sonic 2 SMS as Glitch has made a full split disassembly of the game, and Aspect Edit is a wonderful tool to edit level layouts, and art in not only Sonic 2 but Sonic Chaos and Triple Trouble as well. />

Alright, thanks!
I think I'll start working with this, see what I can whip up if I can get some things in here.

Hi, I'd just like to add to this to say that I am doing a fully disassembly of Sonic 1 Master System and if you could share your work with me Ravenfreak, that would be immensely helpful
I have made solid progress on creating a full editor for Sonic 1. It's still early days (and the disassembly is need to progress further), but it can import the ROM, edit level layout and write out a new ROM.

Sure I was going to contact you in the past but I sort of forgot... Anyway my disassembly is barely a disassembly and was made back when I first started teaching myself z80 asm so it's not the best thing in the world. Hopefully it does help with your research and help you complete your disassembly as well. You can find it here.

Are you by chance going to expand on it to edit the other Sonic platformers for SMS/GG? (Sonic 2, Chaos, Triple Trouble) I certainly hope so... there needs to be more compiled editing suites around here. I'll have close eyes on this. Nice start on Retro, BTW.

No, sorry, Sonic 1 on the Master System is fundamentally a different game that was done by a different company than the others so I don't think there would be enough in common to share an interface. There's already a full disassembly and editor for Sonic 2, and that would be a good starting point, but I started MaSS1VE because there was nothing for Sonic 1 and I felt that was a hole that sorely needed filling since I consider S1 to be better and more 'elegant' than the sequels. tha said, everything I'm doing is open-source, so people will be able to contribute or create their own tools to solve their own needs.
