DS Help Needed

Alrighty, so I made the colossal mistake of allowing my little brother to play with my R4 chip in his DS. I don't know what an R4 chip is beyond something that has fun games on it, seeing as I'm borrowing my current DS and the chip from a friend of mine. So He came up to me and handed me the DS saying it was broken. When I turn it on the screens go white and stay white, but they make the 'greeting' sound as always. It then fades really slowly into the screens with R4 Revolution for DS in the top on and the icons for it in the bottom. Thing is, the colours are completely inverted and kinda washed out. When you choose anything the colors blur and merge together as they fade. It's almost like the screen can't keep up with the commands. Anyone know how to fix this?
