@wiiba :
You have a 200MB hidden "EFI" partition (used to boot your computer with USB instead of internal HDD). that's probably your issue.
The drive is specifically for the Wii ? you don't need to use it for anything else? (like restoring your computer)
We will reset and reformat the drive entirely.
I don't know if there's a way to specifically tell which partition table you want to use. It would be best to use MBR instead of GPT/EFI.
from the disk manager, right click on the FAT32 and select delete partition. (it will delete everything, but you just formated it so you shouldn't have any files on it)
Do the same with the EFI partition, right click and delete.
From here the drive should be empty with no partition.
Right click the empty area and choose to create a new partition, make it the entire disk size. one single big partition. be sure it's "primary" and not "extended" or "logical".
Assign a letter to that new empty partition, you can close the disk/partition manager.
Launch FAT32 formater and format the partition.
Try again with USBLoaderGX.
@thepieddragon:
I've heard emuNAND sometime has issues with "not enough space" when there are TOO MANY space
that's probably a bug with games not checking the size with the correct variable size.
The solution is to put your EmuNAND partition on SD card (or a smaller USB partition or drive). Temporarily if you really want to use USB, then move it back to USB once the savegame is created. or just use SD card if you don't need a lot of wiiware and your SD is big enough.
The problem is USBLoaderGX will tell you that SD is not supported, but you can still launch the game.
Neek2o supports SD on Wii, only the latest beta/leaked version doesn't support SD, but I don't have a way to check which version users are using so there's currently a warning (not an error) and you can still launch.
If that warning annoys you, just use SD card temporarily to create the savegame, then put EmuNAND back to USB.
For the second issue:
I remember there were a game with garbage text too, but I'm sorry I don't remember how it was fixed. I don't remember if it was a setting in the loader or something from the console.
As this is an EmuNAND, you could try to launch neek2o without autobooting a game (go to USBLoaderGX > settings > features > launch Neek)
once you are on the neek system menu, go to the settings and be sure the console is set to japanese language. (if you made a jp NAND I guess there's no language choice ? it's already set to japanaese?)
go back to neek system menu and press 1 or 2 on the wiimote to open the neek hidden setting menu, search if there's a setting about the language. maybe neek is conflicting the console language setting.
Be sure you set the video mode to NTSC instead of PAL or auto, etc.
