Patch 003
Update 2:
I think I started to figure out a couple of things, so I've tried to replace the Guilty/Not Guilty verdict with the English graphics. The graphic substitution by itself wasn't that hard, but I run into a couple of bigger problems.
The first problem was that the japanese kanji have very different positioning from the english text:
After hours of searching Hex values of the coordinates with a hex editor, reading technical information about Gameboy Advance OAM's, trial-and-error tests and a lot of guessing, I finally figured out the addresses of the coordinates, so I managed to re-position the 2 sprites:
I was happy with the result, so I moved on to the "Not Guilty" part, only to find out that my previous change has affected it too! The Japanese kanji were in the new position, and one of the 2 previous sprites was used in inverted colors!
It seems that the rom uses the exact same image and the exact same locations to display both "Guilty" and "Not Guilty" verdicts.
Images from the original rom:
Does anybody have any idea about how I could change the verdict displaying routine?
