My player-hacking vibe strikes again. I got to work editing Super Mario Bros. and 2/Lost Levels.
Daisy is 1P, Peach is 2P/high jumper. Like Super Daisy Land, this is a change-character hack with little else, but I did some minor touch-ups (actually necessary to disguise some color-trimming; the Toad/Peach palette from the original game is shared with quite a few objects in Bowser stages). 2/Lost Levels includes character-specific fire palettes (turns out the code already exists in the game and Nintendo just didn't bother).
There are three IPS patches. One for SMB1, one for the SMB2J FDS rom (which also hacks it into an NES rom so you'll need to change the file extension), and one for a version of SMB2J that was already hacked to NES format.Download the patches here.See the sprite sheet here.
