Can you load several games at once in 1 Arduboy?

Is it possible to put Several games on arduboy?

I mean for example a menu loading on arduboy start.

There’s a couple of multi games about like Atomic Puzzle Pack but otherwise for multiple games you would need to perform a hardware modification like @Mr.Blinky’s Flash cart


That is essentially a no.(since a modified Arduboy is no longer a Arduboy)

and you can’t expect a new-comer to actually modify that

With an original unmodified Arduboy, you can only upload/play one game at a time.
When you make your own homemade Arduboy or Modify your Arduboy with a 3D printed replacement backplate. You can load games from Serial flash like the flash cart project pointed out by @Keyboard_Camper
