For people having trouble I used -
1. Blue Dump German Mod - from wiiuhax ,
2. cios 236 installer mod v6 Vwii Special Edition - also on wiiuhax ,
3. the d2x v10 beta 53 alt vwii - from this site comes in rar file,
has the folder inside labeled with several files inside - just move the maps files and other files inside as well.
4. D2X cIOS Installer MOD 2.2 Download - from filetrip.net ,
5. i put d2x beta 53 v10 alt vwii - 56 for 249 - 57 for 250 and 58 for 251 as the guides state.
6. then your choice of latest wii flow for vwii-wiiu version or gecko usb loader
249 vwii-wiiu version.
use theses files along with ps3 hax steps or othe guides out there and blue dump should work easily and
you should have no problems seeing the d2x v10 beta 53 file.
I had a heck of a time, then found files that actually worked, so if this doesnt work keep looking, keep checking the forums, keep researching google, and you will get it. Hope maybe this helps you as it helped me.
