I have one coming in the mail and want to know how likely it is that this can blow out the fuse in my DS. I have another DS that I can test it on so I'm wondering if it will ruin the system when you initially use it so I can test it on the other one first. Also the menu and interface is very basic so I'm wondering if you can direct me to a tutorial on how to change the skin and if there is a place i can download ones that other people have already made. Thanks
