The Super Game Boy has received a significant upgrade with the introduction of the Super Game Boy Plus, an unofficial enhancement developed by @BucketMouseBite. This new version addresses several limitations of the original Super Game Boy, which allowed Game Boy games to be played on the SNES but had a faster clock speed than the original Game Boy, affecting gameplay and compatibility with link cables.
Someone help me understand the feature to lock a game to the cartridge - does this mean it copies the game data into the SNES cartridge so you don’t need the GameBoy cart anymore? If so, this could give Nintendo’s lawyers enough power to shut this project down, which would be very sad
No, it doesn’t copy the game data in the way you’re describing, anymore than a Game Genie would (it doesn’t either).
And anyway, this Nintendo lawyer fear is getting a little ridiculous in this community. ROM dumping for this kind of data is legal, at least in the United States.
