Hi I recently purchased a r4i-Gold from http://www.nds-card.com, and appearantly from this link http://www.r4ids.cn/news.htm it's a revision C model. I have a 3DS XL Ver 4.4.0-10E, a DSi ver 1.4U and another DSi Ver 1.3U It doesn't work on any of them. Whenever I load my R4i-gold kart. I get a black screen followed by a white screen for a couple of seconds then a indefinite black screen. When the cart is inserted into my 3DS, I get the Konami Digital Entertainment Icon (and some japanese text). Not the deep labyrinth icon. I've tried 3 different SD cards with the Wood Firmware copied on them in the root. The rpg folder and the DS_MENU. DAT file are copied into the root of all SD cards. I get the feeling that maybe it's a hardware problem like the kart could not read the SD card. Can any body please help me. Regards kniteowl Update: I can exit back to the main menu after I load the kart into the black screen by pushing the HOME button.
