Same story here: I ordered two Acekards 2i from ModChip-depot on July 27th, but the only confirmation I have gotten is the receipt of my payment from Alertpay. My order isn't even listed in my Modchip-depot account's order history! I have tried to contact them twice, but haven't received any...
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
