Don't you think this was addressed in your earlier posts? (Do you really need yet another thread..?)

If you can see the tiles in Tile Molester, then you have to figure out how the game lays them out and edit them accordingly.  See for instance https://www.romhacking.net/documents/33/ .

If you can't see anything in Tile Molester, then the graphics are probably compressed, and you have to figure out how to decompress them.
