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.
There are currently both xkas and asar patches in the patches section, better check the "Tool" field when you're downloading a patch so you know what tool to use. That patch you have looks like an asar patch ("autoclean" gives it away).
