Pi Pico Gameboy games?

Hello to all hobbyists,

I've decided to build a Gameboy emulator with my Raspberry Pi Pico and am using this article as a guide: https://www.youmaketech.com/pico-gb-gameboy-emulator-handheld-for-raspberry-pi-pico/ .

I've already ordered all the parts I still need. However, I just now realized that this emulator can only play "normal" gray .gb Game Boy files.

That's stupid because I was counting on the fact that you could also play color games like Mario Kart Super Circuit, because the article shows several pictures with color games on them and secondly a color display is used.

Now the question is whether there is a way to still play games like the aforementioned Mario Kart or at least Gameboy Color games.

If anyone has any idea what can be done or what I need to change to make it work, I would be very grateful.

Best regards and thank you very much!
