This is a release from last week, which was actually recognized, but not posted. In shame here are the late news:

emu_kidid one of the guys at http://www.tehskeen.com has released an early port of VBA to Nintendo’s Wii.

Readme:

Visual Boy Advance Version 1.7.2 Port to Wii

Please note, this is just a WIP build for testing. I’m not responsible for anyones
SD cards becoming corrupted/formatted/etc.

Features:
SD Gecko ROM loading (for now)
SD Gecko Native save/load support
Gamecube PAD support only (for now)
Up to 32mb (256MBIT) ROM support

Usage:
– Place all ROMS on the SDCARD in /VBA/ROMS/
– Create a directory /VBA/SAVES/
– Place your BIOS.GBA in /VBA/BIOS/ (if you have one)
– Boot boot.elf with the tp loader (or whatever else).
– Once loaded, put the SDCARD into your SDGecko (SlotA) and press A.
– Load a ROM, enjoy.
– To access the ingame menu, press X+Y.
– For now, you’ll have to exit to the loader to load another ROM.
– To save your game, after saving in a game, go to the menu and then save.
– Saves are loaded automatically if they are found.

The source is provided but I’ve set the optimization level to -O0 so you can
compile it on dkPPC r14 (but it won’t be 100% speed).
To compile this properly, it was quite a mess, as I had to use dkPPC R13 to
compile GBA.cpp and then R14 for the rest.. I’ll try to sort out the issues, but for
now, the binary provided works fine.
