Help with changing title card colors

Doesn't that use the same color as the hud does?

 

I didn't mean that. What color do you want it?

 

Damn, I was thinking of Sonic 2.

*loads up SonED with a Sonic 1 ROM*

*studies palettes*

Okay, to do that you'll need to change the art that makes up the 1.

 

You can find it by copying the compressed data from Sonic 1 US and searching for that in Sonic 1 JAP.

 

Or you could go and find out what location it was and how long, decompress, edit, recompress and reinsert.

 

There are no breakdowns available for Sonic 1 JAP. Therefore he can't "just go and find the location".

 

Oh.


... So why are you hacking the JAP rom instead of the US one?

 

Nemesis Searcher should find the art in the S1 JAP ROM.

 

Because the Japanese ROM owns. It has all sorts of cool features the US one doesn't, like moving clouds and ripply water.

 

Oh.

 

Yeah, and it fixes that damn double spike bug. Wierd how that reappeared in the Sonic 2 Beta really, like they were working from an earlier version. Hmm and Sonic 3 had the Hidden Palace icon in the level select. Perhaps they always build the sequels of off slightly earlier versions of the game, before they get tidied up for commercial release?
Speculation, speculation, speculation :P

Also good luck with your hack Yoshi, look forward to seeing the next version.

 

Sonic 2 has the Hidden Palace icon in the level select; it's just never used ingame.

 

It scrolls all the backgrounds instead of just Star Light and Green Hill.

And Sonic 2 were built off it before they fixed the spike bug.

 

It's not that hard to find a block of binary data in a revised ROM such as S1J. Simply look at a S1U breakdown, find the location of the data you are looking for, jot down the first few bytes of it in series (the more you jot down, the better your chances of finding it easily). Then, open the S1J ROM in your hex editor and search for that pattern of bytes. With luck, there will be only one match, if not, it's a matter of trial and error (replace each block of data with your own, test results in emulator, lather-rinse-repeat)

Now, code is different because absolute addresses will have changed. But, usually, if you look around a bit you can even find a moved piece of code (it's how I helped figure out how to fix that bug that used to be in Esrael's 1MB S2&K), but it usually takes more effort than just finding straight binary data that would have been unmodified between versions.
