Small (ugly but functional) utility to build a multiboot rom to flash in 369 in 1 bootleg cartridges. Specifically these ones (it will also work in Zelda 7 in 1 cartridges but keep in mind they have half of the flash size, so they can't fit 256 MB like the 369 in 1 ones):
You need Python 3.7+ to run it. It uses Qt6. Simply install the requirements.txt and run main.py.
BennVenn is the original author of the menu being used as a base to generate the multiboot rom.
