Hmm, well, it appears I've hit my first roadblock in YI hacking. I decided I was going to play around with GFX editing today, so I loaded up the ROM in YY-CHR (I always load the ROM...save states obviously don't work for this ) However, as I was scrolling, I noticed that only a few of the GFX can be seen...namely the Yoshi and Baby Mario sprites. Aside from that, it's all garbaged. (I'll assume that they're compressed or something)

My question is - without using Ycompress (I can't...my ROM is unheadered and it will screw up in EggVine if I header it) is there any way to make the rest of the GFX in the ROM viewable?

Thanks in advance...I've never actually edited graphics before

(BTW, this thread is titled YI OW tiles, because those are the main GFX I'm after...forgot to state it above )

Wait, you have to header your ROM to use YCompress?

...couldn't you like, just subtract x200 bytes (or however big the header is, I am not sure) from the sample offset to extract the graphics?

Its been a while since I touched YC, but I believe that you have to enter an address, and if the one it gives you is headered, subtract the size of the header to get the headerless.

Someone verify this please.

Yeah, unfortunately Ycompress doesn't accept the unheadered

I can try what you said....by extracting the GFX though, do you mean just making them viewable in YY-CHR, or another file altogether? Because if I were to do the latter...I would have no way to reinsert them...I think

YCompress reinserts them as well. Just extract the graphics to a .bin or .smc and then if you read the readme it tells you how to insert them.

I don't see how you have problems with this. I was able to edit the graphics and use Eggvine as well without any edits to the header.

Did you start your hack with a headered ROM?

ewww, I think Snestool can add/remove header

Already tried SNEStool, and as I first stated, it just messes up the ROM in EggVine for me after I header it

By the way, here's the message I get in Ycompress:

I think the suggestion is actually to add the header when you're messing with the graphics, then remove it again when you're going to edit in EggVine. It's a bit irritating, but should be bearable in the long run.

Unless the problem remained when you removed the header again. Then... I don't know.

Thats exactly what happens. Adding and removing the header screws up my ROM in EggVine. (I use SNEStool, like Bio said, to do it though. Dunno if a different utility would produce different results or not)

Probably the best solution is to manually add/remove 0x200 bytes at the start of the rom. SNESTool does something weird when you tell it to add a header... looks like it replaces the first 200 bytes instead of adding them. It's fine for removing them, though.

Hmm....how would I manually add one? SNESTool has worked fine on every game except YI for me, so I've never had to

I can't actually see the problem..
Just add the 0x200 header and open with YCompress.

Open the ROM in a hex editor, and add (NOT overwrite) 512 (0x200) bytes to the beginning of the file.

I hate tools that can't detect headers. It's just a few lines. _¬

Is the ROM interleaved? Use NSRT to check it.

PS: If you want to view the memory in the right colors then open a savestate of the overworld (map?) in vSNES (see my signature).

Yeah...I...already got the GFX edited. It's just that error above which is screwing things up now
