I'm having issues with Nintendont not seeing external HDD, i get the "Fat device not found" error. So this i have my doubts, i'm using the Nintendont xbox360 controller support build of the software and on the github page it doesn't mention anything about external HDDs, it only says "unpack it on your sd card". Hdd device is formatted as fat32, 32k cluster size and GC software is placed correctly into the "Games" folder
