so I'm trying to sell my DS Lite, on which I've used the R4 card for a while [with woodr4 firmware]. I went to the store, and to my dismay the employee was unable to load official game cartridges it would just skip to the ds menu. he said that he knew of the problem for certain DS models, but wasn't sure of it for the DS Lite. Could the R4 card be the problem? Can it be fixed?
