[1]: to edit:
1) open ROM in nocash and set a breakpoint for [0x2007000]?! during a transition.
2) dump (0x1000 bytes) using no$ → window → “binary dump to .bin file”
3) export generic BG GFX as raw (do not use a file extension)
4) pad the exported generic BG with 2048 bytes of 00
5) MAGE → tools → compression → lz77 compress file… exported generic BG and dumped tilemap
6) append both files to the end of ROM using a hex editor. Take note of the offset before you paste in the bytes of the first and second file.
7) reload rom in MAGE, then tile table editor → offset tab → punch in compressed tile table, compressed generic bg, and generic bg palette.
8) make desired edits, then export raw. rename file to “tt.bin” then grab This C code.
9) go to jdoodle and paste in the code.
10) upload tt.bin, then run the code. you should get tt.rle.
11) copy the contents of tt.rle in a hex editor and paste-write over 0x8364F80 (Ctrl+B)
[2]: To view in MAGE, add tileset (blank), open tileset editor, substract two from offset (0x836559E) and write it to tiletable pointer, apply.
