Okay, So I bought a new Japanese Dslite and a R4 Revolution DS. Came home...no cd in the package. No problem...went to the website put the latest English kernal on the Micro Sd card and some games...no prob, soon I was playing New SMB...however I turned off the DS to change to a different gave after saving. Big Mistake. Since then all I get is a "hardware is incompatible" message. I have changed the firmware many times. I tried a new Mirco Sd card. Nothing is happening. It is one of those new R4s with no spring so I am not supposed to hear a "click" when I put the SD card in, right? Any help would be great...I emailed the manufacturers directly, but I dunno what that'll do... :'( Do I have to exchange it or what? If this topic has been covered a million times, I apologize. I sifted through dozens and dozens of pages and the search option is off soooo..... HELP Please!!!
