I know this has already been done, but I recently won four consoles in an eBay lot (GBA SP, GBA, and two DS Lites) and got them all to work, with one DS Lite turned into a GBA. Here's a preview: I suppose there are a few things different with my mod. With just a few touches of the soldering iron, I can completely reverse the mod, and if I decide to buy a replacement top screen ($8.00) and slot-1 card slot ($2.00), then I basically have a fully function DS Lite. The current mod has: stereo sound fully functional touchscreen, and the brightness can be adjusted wifi microphone can autoboot or manually boot Future plans: map shoulder buttons onto X and Y (works better for fighting games) though this may require permanent mods. Anyway, I'll work on putting together a full video tutorial sometime soon for those interested.
