Moving levels from one Mega Man 4 hack to another

Post by cschifani » Mon Apr 20, 2020 7:41 pm

I would like to be able to take certain levels from one Mega Man 4 hack and port them to another Mega Man 4 hack, both using the PRG0 Megaman IV (U) ROM as a base. I understand (I think) where the level data is from Matrixz's comprehensive document on Romhacking.net, but I think that something more--the CHR data for each level--is also needed to enable level porting. How do I determine where the CHR for each level (there are 16 total) is, and how long it is. I know from Matrixz's document that the CHR data presumably starts at 20011, but I'm looking for guidance as to finding the rest of what I might need. My sincere thanks in advance for your kindness in providing help with this!
