I have 2 R4 gold pro flash carts I bought a few years back not sure if what i have is an "authentic" or not but presumably the are. I will include a picture if that helps. Anyway my problem is I have a dsi and a dslite and I once upon a time had these cards working for all my roms life was good. Eventually update was required or something but they both stopped working . Ive been looking for proper firmware for the better part of an hour and cannot come up with any. Can someone please help me by pointing me in the right direction in regards to obtaining the files and instructions to get these cards working again. Thanks much appreciated.
