Nah This is sick!!

I knew that if you hold Start or Select in older games, they will play in their native resolution. But I didn’t know that Game Boy and Game Boy Color games also had these frame designs around the screen. You can even change the gray color on Game Boy games to green by holding L + R and pressing Y.

Sadly, this can’t be done for GBA games because they run natively and not through emulation. But still cool that the added this to the gb and gbc games 😁👍. The 3ds keeps surprising me man!!
