So apparently, despite having over 400 exclusive games, the GBC s not a new generation to some because there were cross-gen games released for it that also worked on the original Game Boy, just with less features.
Okay, well, the Zelda Oracles games came out after the GBA was out, and have an extra feature (a shop) if played on a GBA. Much like how you got extra features on a cross-gen Black cart GBC game.
So I guess that is proof the GBA was a GBC revision?
Again, just like the other guy you don't get it.
GBC isn't forwards compatible. Where are the GBA games I can play on my GBC then?
There are Gameboy Color games I can play on my Gameboy, that's forward compatible.
