Kuwanger has released a new version of Goomba Paletted, heres the info:
Goomba Paletted is based on FluBBa's official Goomba. The major additions to my unofficial branch include custom palette support (palette is stored per game, though selection of palette is global) and custom border support (how global these are depends on your setup).
v2.32 - 2006-03-19 (Kuwanger)
Fixed a nasty bug involving the improper updating of totalstatesize--
probably my fault
This release works on GBA, GB Micro, Gamecube Gameboy player and also Nintendo DS with Flash Carts.
