Hey there people, Very new to this. I have a friend that just updated he firmware to DSi to 1.4.3 and now the cart does not work. I have tried the newest 1.47 firmware for the R4i 1.4 but when I had a real good look at the cart it say R4i v1.4 but the site says www.R4iSDHC-com-tw. I tried the newest firmware from there but it was last updated in 2010. Is there any other firmware out there that may work?
