(I posted this on the EZ-Flash forums but I have not gotten a solution yet).
The R button on my DS Lite is kinda sticky, so I used it as a good excuse to upgrade to a 3DS. However, my EZ-Flash V doesn't work on it, so I'm just going to finish the last game I have for the DS (Yoshi's Island DS)...
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
