Quick questions

Is it possible to access Wii games across a network, for example if I got the Wii games on my computer, would I still need to back them up on to a disc to play them or is it possible to do it over a network?

Also, I'm not sure if I've got all the latest software on my SD card for the Wii.
In the 'wad' folder, I have 3 different files: neogamma R8 b7.wad, USB Loader GX-UNEO_Forwarder.wad and USBLoaderGX-r850.wad.
And at the root of my drive I have two different wad's, named 'IOS38-64-v3610.wad' and 'IOS70-64-v6687 [Patched][FreeTheBug].wad'

Can anyone help me out please? :D

Take the original game and rip it to a HDD using USB Loader GX or any other loader. Post a sysCheck. Search the forums on how to.
