Hey I am new to this kind of stuff and I've been working for days trying to get my new R4 SDHC flashcart to work. The only firmware I am able to run on there is the one from the producer's site (R4 SDHC) and it ran only one game that I have. If someone could give me a step by step on how to get my cart to work, I would be forever grateful. Thanks! What I have: DS lite R4 SDHC 4gig SDHC card
If you do happen to have an R4 Ultra are you shit out of luck? I've been trying various different ways of getting Pokemon Black/White to work but to no avail.
If you find out if yours is a R4 Ultra (which I have though I'm not really sure. Never really thought SDHC and Ultra were different.), the AKAIO 1.8.1 firmware works fine for me. It also has a AP bypass feature that works on most games clean or otherwise. http://www.r4ultra.com/download/AKAIO_1.8.1.R4U.rar To get to the AP bypass... Hope this helps.
