Technically super Gameboy enhanced games are a mix of SNES hardware, Super Gameboy hardware, and Gameboy...
They function very technically different than Gameboy Color.
Including special borrders, extra sound effects, SNES music, sometimes graphical overlays, or full blown SNES games (Space Invaders had an entire SNES game built into the Gameboy Cart), special full color menus, and ingame artwork, and different color themes for levels..
Gameboy color is incompatible with Super Gameboy enhanced games, and Super Gameboy is not detected by Gameboy Color or Gameboy Advance.
It's a very special technical feat of SNES/GB technology blended to do some very unique things, that you won't find anywhere else.
It's better to think of Super Gameboy as its own unique 'console' released between classic Gameboy and Game Boy Color. But its own thing with hits own unique features, and technology, and is SNES only.
I already know that and I should have mentioned it and I never liked Super Game Boy when i was in 20's. Hate it and I prefer Game Boy Colour because it was felt like NES version.. Great colour. Thats why I dont consider Super Game Boy to be part of SNES Console and Mini at all.
I can't link to roms, but for those that search, there's a colorized hacked version of Super Mario Land (Gameboy) out
Works perfect
[EDIT]
Pokemon Red also has a color hack floating around
Dont like it. I had seen it before. I prefer NES version and Super Mario Bros DX better than this one.
