I have experience with this guy http://wiinewz.com/forums/installers-repai...california.html. he installed a d2ckey for
me a couple of years ago. excellent service. sent it in and was shipped back the next day.
Can't find any threads about this particular issue on GBAtemp or the wider intarwebz. Saw one video on YouTube that seemed relevant, but it was some dude with the same issue, no solutions offered in the comments. :/
