Few games I'm having issues with, have had my wii for 7 years or so & updated the hacks on it not long ago. It's having issues with a few games I've introduced but a lot work just fine.
Metal Slug 4 Neo VC ( resolution issue I think) Black screens, you can hit home and it will refresh a frame...
@K3Nv2 I got some cheapies at wallys, that are pretty good, already have lost a few expensive ones (one falls out and gone, can't find) while cutting grass so bought some cheap ones, and of course never lose these cheap ones. (Cheap meaning only $35, compared to air buds which I only have 1 of 2 now)
