For the looks of the code, what you have to do is extract the Overlay 0 file with NSMBe, give it to that tool and it will change the Class ID of any sprite in it, and then importing it back to the ROM with NSMBe.

Uh, and how will you handle compression?

Look at plans.txt in the trunk of classidtool.


Absolutely correct.


For now, I would use NSMBe to decompress, but once I recode all the NITRO Filesystem stuff in Python, then I can decompress it myself.

Update:
Yahoo! Direct ROM manipulation is now supported! Just make sure the Overlay0 in the ROM is decompressed first.

Not everything is going as planned however. This thing, is being able to make a GUI interface. Everything else that was planned in plans.txt has been implemented. Once I figure out how to make GUIs, ClassID Tool will get one.

Oh nice You moved it to GitHub
Will try it out when I can
