multicarts are cool, so im gonna make one

i have no information on how to do this, so im just gonna make the simplest type of multicart, literaly just loading different carts for different levels, i dont know why multicart games like poom dont use this! although, i may be wrong about how cart loading works... hopefully i dont need to worry though! ill try to push through and make the best cart ever!

good luck, its easier than you think to set up. that menu i made was for testing multicarting as a concept
