This is my first rom hack, just patch Wario Land, enter the first course and fight all the bosses in order. More details in the readme. The boss rush functions as intended but its placement in the game is crude so I'm 50/50 on making it a proper level and finding a good location on the map for it (which will involve more reverse engineering as I haven't looked at how the map works). Open to ideas.
p.s. if you don't look at readme's, back up your rom!https://mega.nz/file/QY1kHShb#lWFd9o4b4qCF9fa895xsV5ggWL067Z5BKkSvaT888yE
