I bought my son a DSI XL today and had already bought an R4 Gold card.. The firmware that i was told to download would not work on it. the site i have to go on to download is www.r4igold.cn. I finally found firmware on another webpage but only a few games worked..I was getting error messages.. Im not sure why as the first r4 card my son had for his dslite the games worked perfectly.. For some reason they arnt working with this card. Keeps coming up Rom loading Failed. load rom errcode=-4 please reset system. Never had this problem on my ds lites. Anyway i thought i would just set up his ds for him as he asked to download something from the ds shop. As i went to do this it said there was a system update that needed to be done before he could go to the shop. So unknowingly we did the update..Now when i put the card in i get an error straight away saying An error has occurred Press and Hold the POWER Button to turn the system off. Please refer to the nintendo DSI Operations Manual for detail. Is there anyway i can get my sons dsi xl firmware downgraded so the R4i card will work again?? Or is there a fix out there i dont know about yet.. My son is devastated as all he wants to do is play his games. Thanks for your help in advance.
