Alright, so I bought an R4i Gold from nds-card.com, paid for it and all went to plan. It came in the post today, so I patched it all up and put the newest Wood R4 firmware on my SD from the website. I copied over some of my roms and homebrew, but none of them load. When I select them, I just get the black screens with the white Loading text on the bottom. I can't load any of my commercial roms, or any homebrew either. Any ideas as to what's wrong?
