So guys i have a problem with my R4 SDHC flashcart.. I bought this flashcard from a site: There were guidlines on their site on how to install the firmware for the flashcart and so i did, they said that i needed to download this firmware: http://www.r4bestell...5/R4DS-SDHC.rar and so i did. But when i tried it on my Nintendo Ds it keeps giving me a blackscreen with the message: "Please upgrade the hardware for support latest firmware." I tried the newest firmware from www.r4sihdc.com but that one just gives me a whitescreen.. what should i do??
