[SOLVED] USB (ntfs) access from program.

[SOLVED] USB (ntfs) access from program.
March 25, 2014 07:02PM
Well. My wii mame works good with games on SD.
But now I want play games from USB formatted in NTFS.
I downloaded and installed libntfs and modified mame code to work with USB, but...does not work.
Then I tried using the simple example from libntfs, but does not work either.
Simply "No NTFS volumes were found and/or mounted."
Loaders work very well with the same USB disk.
Someone can help me?

PS: I've use "formatted code", but signs \< and \> are gone...

Solved using code grabbed from WiiCraft project (thanks filfat!).
Files: devicemounter.c & devicemounter.h from Wiicraft_launcher.
