My Sonic 1 Hack

I've been able to recreate the same effect somehow in Sonic 2... I don't remember why... might even have been in Sonic 1 and been the same thing. I dunno, quite frankly.

 

If I remember correctly from my Sonic 1 hacking days, in GHZ there are two sets of loops, one that works, and another that dosen't. Try using the other loop.

That's because Sonic 2 uses a tag objects to switch between the high plain and the low plain. If you don't place these tag objects in the corect locatons then the loop will not work. Sonic 1 does not use a tag oject.

 

Good, so far. I'll be awaiting the first release.

 

The checksum on the rom is not right, thus it is generating the redscreen error for me. I went ahead and fixed it on my version, and right now its not a big deal considering you are still working on it, but when you finally do release another version, it would helpful to the others to fix it.

Anyways, the game so far looks good, but as you said, there still a lot of work to be done. The pallet looks ok, but the level layout requires a lot of work. There are several holes (caused by the unaligned tiles) which can cause sudden death (unless you purposefully did this). Still, it looks like it has potential, especially due to a small number of Sonic 1 hacks out there. Keep working on it!

 

It would take a LOT of skill but I think you might be able to do it
If your good at hex editing =P.

 

Look in the pinned topic on 68k resources. There's a hex primer there.

 

I am sorry, I don't think it is possible at the moment.

 

Correct. It is impossible for music from Sonic and Knuckles to be placed in Sonic 1. It would be almost impossible for music porting. You would have to actually edit the games music, and when I say edit, I mean manually change the notes. The tool they used to produce the music for each game was different. Yes, I know that Genesis Music runs on Z80 Processor, but the system in which the music was made was different for each game, therefor making it impossible/nearly impossible to directly port music. I believe the only know Music hack is Saxman's Jingle Bells Oil Ocean hack.

 

Sonic 2 Omega is starting to have diffrent music.

This is the my better music changes.

This music should be in Omega in the next version.

 

Yes. With the use of a sprite editor, it is very possible to port sprites. Sonic 3 to 1 sprites have been done before. The only sprite editor I can think of at the moment is SonikSprite, which can be very annoying. Try Sonicology for other useful resources within game editing.

EDIT: .hack//zero, kudos for your attempt at this. It seems decent, and Sonic 2 Omega is already one of the hardest worked on hacks in existence. I wish you success.

 

Didn't Sonic 2 Delta II have Marble Zone music in it? I know it's not music porting into Sonic 1 but it is music porting. Should you be able to just find the location of the music, copy the code, paste the code in the rom, and change a pointer? I don't have a clue on how to find the pointers for the music but shouldn't that work?

 

I think Sonic 2 Beta uses a similar music format to Sonic 1...and if I remember correctly, they're both uncompressed, therefore making porting easier. Though, I could be really wrong, so don't take my word for it.
