R4DS Password System

I've searched the entire forum along with other forums and I can't find it. I'm looking for a App/Program that password protects your R4DS. I need it ASAP because my brother keeps stealing my DS and hogs it, playing my R4 for hours. If anyone knows of this App/Program or anything similar, plz tell me ASAP. Thank You!

 

protecting just the use of the r4? or like using other ds games also?

 

Is it even possible? I need it so that my little brother does not view my videos.

 

I didn't know they has Girls Gone Wild in dpg format.

 

Just pop the R4 out, put it in its case, and put it in your pocket.

 

Yes, I mean a program that completely locks the full use of the R4, which includes games, vids, music, etc.

 

You may have thought I was kidding, but taking the R4 out of the DS and putting it in a case in your pocket and carrying it around is going to offer you the best security. And be your easist solution.

 

the only thing that i know can do it is the old and forgotten GBAMP.
and im guessing the slot 2 m3s can too.
im not so sure about the m3 simply and other slot 1 devices.
