Tip: Switch palace switches normally disappear if you replay the level. However, if you insert them as direct Map16 and use the hex-edit at $00EEB2 in the ROM map, you can replay the level without a problem.
Approved since the update just added the json files. Note that the ExGFX provided is only needed to have the correct graphics show up in Lunar Magic (the sprite works fine without it), so if you need something else in SP4 don't insert it. Tested with LM 3.10, pixi 1.2.12.
