Using Sonik Sprite I assume?

You will notice the purple squares when using Sonik sprite, those are places that you cannot draw on due to the mappings.

Mappings are somewhat complicated. I don't think there is any way to edit character mappings other than hex.

I don't even think the mappings format in S3K is fully documented. (Actually...Lost knows, but I think he is banned from here)

In short, it's probably more trouble than it's worth. It would be easier to edit his animation to display the other pose.

Lost is banned? O_O....By edit the animation did you mean put his old one back in OR somthing else?
and if there is no easy way to do it, i'll have to look into the hex of it...X_X

Rika, you are actually quite mistaken. Character mappings are in the same format as normal mappings. The difference is how they are stored. Ask Ultima for more info.

By edit his animation, I meant to edit what frame is displayed. It may be easier to do this than to edit the art and mappings.

But...I am not sure if this kind of info is even documented for Sonic and Knuckles. You might have more luck if you post at the SWS2B.


Yeah, Tweaker, looks like your right.

Editing mappings is simple enough. All the documentation you need is on Sonicology in the mappings guide section. Adding animations is a bit harder though if you plan to do that.

The format for character mappings is the same, but it's a little bit trickier to work with. You see, since only a certain number of Sonic's tiles are loaded to VRAM at a time, you have to make sure that the correct art is loading into VRAM as well. You need to do this by modifying the pattern load cues. Again, you can find documentation on this on Sonicology.

The only reason that Lost Library can't read character mappings properly is that each frame, the mappings will specify to read from tile 0, and Lost Library reads from tile 0 in the art set. However, the mappings read from Tile 0 in the VRAM, depending on what the load cue is loading up, so Lost Library is constantly loading the wrong thing, except Sonic's standing sprite (coz this happens to start from tile 0 in the art set). Hope that wasn't too confusing =P

Anyway, editing the frames is nothing more than a simple byte change. You just need to know which frame each value represents, which is why it takes some trial and error to get it right.
