Goomba is a Gameboy emulator for the Gameboy Advance. Beyond the advantage of being able to store many games on one cart, Goomba also includes save states and customizable borders. At least, Kuwanger’s fork does. Also available are many palettes, along with the ability to make your own.

Release notes:

This is mostly a repost of v2.36rc1. It has a few modifications, to better reset for the Supercard. This means exit should work properly under Supercard, EZ4, and F2A. Saves should also function properly under EZ4 and F2A without any patching.

Also included is Asaki’s mix of the Gameboy Color palettes.
