So as the title reads, is it possible to replace the 2 rom files in any of the many 2-in-1 GBA games that were released over the years, pretty much any of those seen on this page: https://www.google.com/search?q=gba...XXLc0KHdVCBJoQ_AUoAnoECA4QBA&biw=1920&bih=920
You might think it pointless to do when we have flashcards and emulators, and you wouldn't be entirely wrong. This isn't something I need to do, but it's something I'd love to try and do if possible. Specifically, I'd like to see if I could replace the 2 .gba roms in such a title with the 2 .gbc roms of Zelda Oracle of Ages and Oracle of Seasons. I know the fact that i'm trying to do .gbc games in place of .gba games adds an extra wrinkle to the question as it is, but it seems like something that would be at least feasible to me. And then beyond that, if that even can be done, would it then be possible to alter the game selection menu screen before you launch either game? Obviously, I'd like to the choices to reflect the new titles injected into the title if this were possible.
