everything else like swapping gfx, music, palettes etc is supported.
here are a few things to check for:
- make sure the level is not using any "direct access map16" tiles.
- make sure the level is not using any sprites that are not using the right GFX files.
none of the things listed above actually work in smw and get automatically patched into the game by lunar magic.
because of that, the game will either crash or not compile at all, please fix those problems and try again!
