First of all, i am writing this tutorial to clear the air about something in the ultimate tutorial. In the tutorial, it is stated that a snes pallette editor is needed. Air clearing time.
1.Get the emulator, rom and a hex editor. This is all that you need.
2.We are going to do the simple task of changing marisa's hair to eirika's colour.
3.Now, open up your vba and rom and go to marisa's stat screen.
4.Now, go to tools>tile editor, and tools>palette editor. Now, in tile editor, click on the third option under char base and slide the palette stick until the colours work out. Click on her hair to get the three colours' red, green and blue values.
5.Now, in the pallette editor, search for those colours. Marisa's, like most (but not all) are right next to each other.
6.Now, check to see what are the last four digits in the boxes marked values. Marisa's are 7e1f, 6d5a and 4530.
7.Now then reverse these like this:7e1f=1f7e
6d5a=5a6d
4530=3045
8.Now, open up your hex editor and search for these new values (all at once)
9.Now, get Eirika's values-6377, a262 and4541.
10.In the hex Editor, replace Marisa's with eirika's.
Voila, custom Marisa.
