Hi, I would appreciate an option to be able to use SGB borders in GBC mode for games compatible with both. In current implementation the borders are black in GBC.
Thanks

I could be wrong but I assume it may be because games that detect GBC hardware don't actually bother to signal the hardware that there is a SGB border?

This is correct to the best of my knowledge. The software (game) knows that SGB does not use GBC hardware, and stops sending SGB commands when operating in this mode, so the SGB (or core) has no way of knowing it wants to do these things.

For the black cart GB/GBC games you can get them to load in SGB mode by setting the System to GB. If you leave it on Auto it will be detected as a GBC game
