This isn't anything big, but I'm hacking Dragon Warrior Monsters (GBC Game) and I wanted to edit the level data. I just want to edit the tiles, not the events, npcs, or anything like that. If I'm correct, the tiles in rooms (Not the 8x8 tiles used in VRAM) are 32x32 px wide... Basically I need help on how to get them. I spent hours going through the memory editor, and changing every still byte I could (With automatic update on) and all I really changed was VRAM, color of myself, and some tiles. I also stood in one room and went to the memory editor and then moved, and checked for any bytes that switched. I did that throughout the whole ROM (Atleast with the bytes that weren't moving, cause I knew those couldn't be tiles), and I got nothing. I know that you can find where tiles are placed in a room through a memory editor, because VRAM is at the same place per room, yet has its own separate offset for real. I figured that level data was the same way, all of the bytes making up the level were in one spot for all rooms depending on which you are at, and then are somewhere else in the rom itself.

Thanks for helping me if you can

Well, the only debugger for GBC I have is the one built into BGB. I barely know how to use it. The only thing I know about debuggers is if you put a breakpoint on a certain line and the rom runs into that line, it stops. So I don't know how to do what you said

Well, in BGB, I went to the VRAM viewer and got a tile I could modify (As much as destroy, or change the tile itself) and put a breakpoint on both of the offsets (Map address and tile address) and done all I could to the tile, and it doesn't break. I'm not sure I understand what you mean by changes when you walk towards it, because no tile in any game I have changes when you look at it.
