Hey all. I've been wondering if something like this is possible. Basically, I was thinking of making a 2 in 1 cart having a menu screen so you can pick your game and then having it load the game using the roms.
I currently have this situation:
-Both NROM roms without their ines header nor their CHR data embedded within them. Just the PRG data and each PRG is stored in a different bank of the AOROM game.
-In the "master" rom, I have it grab the appropriate CHR data and write that all to RAM and then I try to bank switch out everything into the appropriate game.
This actually kinda worked, but the games don't play. One game simply loads the music and the other loads nothing.
I tried clearing zero page with 0's, but that didn't seem to work either.
I don't know if there's a way to call the reset routine of the games or what, but is what I want to ultimately do possible? Thanks.
