I got a wiiNTSC, d2b chipset, wiikey, and (as far as i know) the latest firmware.
The wii was modded back in february, and all variety of back-up discs worked on it.
I have two discs from this kid down the hall burned on Memorex DVD-RWs, which still function properly
I have a number of discs of my own, all backups (endless ocean, rayman, fire emblem, etc.), also burned on Memorex DVD-RWs, except newer, which do not work anymore.
All of these discs used to work perfectly, but now only the ones burned by my friend work on my wii (and original games work, of course). Is there anything I might have done to cause this? I'm currently in the process of trying to make mario kart wiiNTSC work on my wii, and since i began this endeavor, none of my own burned discs work anymore.
