Hi folks, I'm new to this whole NDS rom malarky and I'm also suffering the black screen of doom when I try to run WarioWare DIY. I have an R4i Ultra card running firmware v1.55 (as found here http://www.r4ultra.com) but in the OP on the thread there are several fixes for R4 cards, but I do not know exactly which one I should be looking at/using since there are many different versions of the R4 (or so I'm told). I don't suppose anyone could actually help me in figuring out what system/firmware I'm actually running and which fix would be best for this card, and which fixes to look for in the future. Thanks in advance.
