if you want to load wbfs games disc from neek, you need to emulate the Disc Interface (DI)
if you disable DI, you can't load disc games in the disc channel.
if you use neek, don't use game loaders !!!
that's the purpose of neek : no cIOS, no game loaders !
if you want game loaders, then why use neek?
if you want darkcorp or neogama to play burned discs, then you also don't need anything at all !
just use a USBLoader like USBLoaderGX or Wiiflow or CFGLoader, they have an option to load discs.
Remember, your wii need to be old to read burned disc, it's a physical requirement.
You better just insert the disc and dump it to wbfs instead or playing from disc (at 3x read speed instead of 6x from original discs or faster from wbfs)
You are planning to use a 8GB USB, so I guess it's flash drive ?
Flash drive .. .right ?
didn't you read enough message on the forum about users complaints?
if you really want to use flash drive, up to you. don't ask for help.
