I'm a little bit let down, but I know I shouldn't have had my hopes up in the first place.
I just can not get Loadiine to see games on my 5.4.0U system.
Here was my step-by-step:
1. I setup HFS with the all the MP4s provided by 05SonicBlue.
2. Inserted my FAT32 SD Card into the Wii U (It's a Maxell 2GB SD Class 2, just something I had lying around. It's not SD-HC, just SD.)
3. Turned the Wii U on, went to System Settings, backed out, opened Internet Browser, and launched the Loadiine Kernel Exploit.
4. Gave me a message along the lines of "Success! Restarting browser...)
5. Launched Loadiine v1, which kicked me back to the home menu.
6. Launched Mii Maker.
7. Loadiine launcher popped up, but it said there were 0 games.
I triple-checked that I formatted the SD card as FAT32, which it is.
The folder structure for the SD Card is this:
SD:\_RPX\DuckTales\WDKE.rpx
SD:\_SAV\WDKE\c
SD:\_SAV\WDKE\u
SD:\WDKE\<-GAME FILES HERE->
Does anyone know what I'm doing wrong?
