Would be so grateful if update this as soon as it is fixed! This is a must buy for me, but not end gh space at the moment!
USB storage support is pretty broken as far as I can tell. Did you manage to get the expansion to show up as internal storage? I was able to install final fantasy IX (another large game) by basically uninstalling every application, installing, then moving the game to the USB drive. But most of the apps won't move to the other drive so my 64gb is mostly useless still. Really hope they release and update to fix things.
Thank you for bringing my attention to this port's existence!
