Is it possible to play Game Boy Colour games and Bame Boy Advance games on the regular Game boy system ?

Gameboy Color games that are on black carts have two versions of their games, one of which will run on the classic Gameboy (the game will not be in color, obviously).  The Gameboy Color games on clear carts will only work in a Gameboy Color.  Gameboy Advance games will absolutely not play on a classic Gameboy.

Yeah. The first generation of GBC games were black and shaped exactly like the older gray GB carts. These black ones are backwards compatible not only with the Gameboy and Gameboy Pocket, but also feature the quasi-color "enhanced" mode of the SNES' Super Gameboy. Not every black GBC game has it, but a lot of them do.

I'm sorry if this is slightly off topic, but I had a question about the super gameboy with gbc games. Now, black carts work and green ones don't. I noticed with those green carts however that they have a custom "uncompatible" screen.

For example, I would try Snoopy Tennis and I'd get that screen with a picture of snoopy angry with the tennis racket. So if developers had the effort to do that, why couldn't they just make it compatible in the first place?

Hardware limits.

Making the game work for GBC and GB requires that they, more or less, create two games.  Check out the rom sizes for the GB/GBC games, they're about twice the size of a standard GBC rom.  That's the reason.  It's capable of doing it, hardware-wise, but the developers didn't want to make two games.

The Super Game Boy wasn't that widely supported even in its day, but the SNES was pretty much obsolete by the time the Game Boy Color was around.

I remember how some (mainly first-party Nintendo) Game Boy games had a little icon on the box showing that they could be run in 'enhanced' mode with full colour and custom borders on the Super Game Boy. I only ever had one game like this myself, a Donkey Kong game. I guess most developers didn't think it was worth the effort and it certainly wasn't a selling point.

Lost World is one of those games. It says so on the cart. And I was wondering why it looked the way it did when I played it on an emulator. It was one of those games I downloaded & found out it was so good so I bought it.
