This clone isn't too mature right now, but it works:



http://code.google.com/p/l-echo/

I really, really want to port this to the NDS, but it won't work (it would power up and leave the top screen black and the bottom screen white). Modified source code:

http://l-echo.googlecode.com/files/n-echo_attempt-3.zip

So can anyone please help me ?

Oh and that source code is outdated (0.0.7). I haven't made the changes to the main tree yet (which is at 0.1.0):

svn checkout http://l-echo.googlecode.com/svn/trunk/ l-echo-read-only

Thanks
