ROM Hack any other way to play with sonic advance sprites in sonic rush beta?

[Deleted User]

since really the only way to see it is with a camera glitch, is there a cheat code or something that lets you switch to it instead of having the 3d sonic model?

You might need to go into further detail there.

If I am understanding it correctly.
At some point the beta for Sonic Rush (one video called it the E3 demo) leaked.
If you manage to glitch things then rather than display nothing the game will fall back to just being the 2d sprites (seemingly from Sonic Advance) rather than have nothing at all which is fairly common both as a general failure prevention and to have something to do while the 3d animators are doing their thing.

This fallback thing presents an opportunity and likely makes life a bit easier.
Cheats might be harder for this one -- I don't know if they can usefully write the 3d processor on the DS ( http://problemkaputt.de/gbatek.htm#ds3dvideo ) to mess up the model or animations, and while you could alter the binary in memory to do an in game command then if you knew that you would have. I would instead see about corrupting the model and/or animations (hopefully the nsbmd format by this point but it might be early enough to still be a custom or precursor format).

I don't know if deleting it or overwriting the file with random gibberish will do (might just crash the game) but worth a try. If not then a glitch is likely more that the animation at that point made an illegal combination and it stopped displaying it, that would be something to investigate there.

yeah it would happen when you went to that spinning thing that looks like a bumper and then you would jump off when you're at the right of the area, and the camera shouldn't snap and when you would hit the ground it would show the advance sonic sprite for a split second.

ok so corrupting the model just crashes the game and the emulator...

Might take some more directed corrupting then.

Though I forgot to do a sanity check. Open up the VRAM viewer (set to automatically update of course) when you are running around -- is the 2d sprite artwork present there? What about in those cases where it is visible for a split second?

On Windows at least (some Linux builds lack things) then under tools should be various things like view tiles, view maps, view OAM (OAM = object area memory, objects/objs being another term for sprites, though it might literally just be the OAM memory data that is controlling screen location and some other things) and so forth. Try those.

It's not in OAM, only the HUD is, but I'm at the frame where the sprite shows

It is possible for something to be loaded very quickly into and out of RAM but if it is not in OAM then I would wonder if it is not a texture or something similar.

It's a sprite in .bac format
