Portable Music History just went public beta.
So far there are a few sets available for download, with new ones added every 6 hours. For the next few weeks there should be only Game Boy rips there, but once we reach October of 1990 (in about 100 games), Game Gear ones will start showing up too...
although i ended up accidentally changing my nand with no way of going back bc i didn't know you needed a gamecube controller to restore it (i have a wii minus/1.1, which doesn't have gamecube controller support)
and if i find the sd card i have my NAND backed up on, i can not only restore the NAND if i solder the right part in, but i can also put my NAND on dolphin, then i can play dolphin online, like PMEX Remix or MKWii Riibalanced
