super mario world plus is an improvement hack that adds separated player sprites, improved sprites, fixed glitches, an added wall jump feature, the ability to re-enter switch palaces like castles, new level themes, new music, red and blue blocks giving powerups, and an optional co-op hack version (it’s kinda buggy though.)
if you patch this on a .smc rom of smw, you may need to remove the snes copier header using this patcher: https://www.marcrobledo.com/RomPatcher.js/ it should work fine on a .sfc rom of smw though.
