My Wii wont play back up games anymore?

You just answered your own question.

"It has been hard modded."

The Wii is not designed to have any modifications performed on it by a non-Nintendo technician. Please purchase a a new wii, new legal games and do not mod your wii. Thanks.

WAIT, WAIT, HOLD-ON WAIT A Min don't listen to them nobheads and don't bin your wii with 30mins you could moid the wii to accept a usb hdd with games on it that will run perfect on wii

get verbatime or verbatim or whatever how its spelled brand discs. make sure theyre dvd-r. they work like a charm. all the time at full speed. look them up and people will tell you how flawless they really are!

it's because you are a dumb f*ck who ruins a perfectly good console by adding crap too it.

well done, you have reached your target of having to dish out more cash for a new console.
