I am a NERD ;-)

PC SPECS :-

1: PIII 750MHz (over clocked to 800MHz), 64MB Dual Screen Graphics Card, 256MB Ram, 20GB Hard Drive, Win 98 + Ubuntu 7.10
2: Celeron 1.2GHz, 16MB Graohics Card, 512 MB Ram, 2x 15GB Hard Drives, Ubuntu 7.10
3: Celeron 1.2GHz, 16MB Graphics Card, 256 MB Ram, 20GB Hard Drive, Win 98
4: AMD Athlon 1.8GHz, 128MB Graphics Card, 512MB Ram, 80GB Hard Drive, Win XP
5: P1 233MHz, 8MB Graphics Card, 256MB Ram, 3GB Hard Drive, Win 95
6: LAPTOP : Celeron 1.7GHz, 230MB Graphics Card, 1GB Ram, 2x 20GB Hard Drives, Win XP + Ubuntu 7.10

I am currently coding ( attempting ;-) ) a package of seemingly random bits of code that may server a purpose, may not but, it is just to learn C and have some fun with my wii.

If someone can improve it put any improvements in the Updates section at the bottom ;-)

Updates

These may be updates/fixes for the code above

• I was able to compile your code. I think you need the most recent cvs of the libogc use Drack's guide

• • Thanks for that now i just have an error about usb functions in libbte

Also you should not include .c files in the header.
