Mp3 player into a controller? please read

Hi im new to this forum so hey, if i do anything wrong please let me know.

Right back on topic, i want to put a cheap mp3 player in to NES control pad. I want to configure it so that the head phone jack comes out of the lead hole. i also want the volume up and down and song skip forward and back in the directional pad and the play and stop in to the A and B buttons. In research i did a search and found a German guy that had done somthing similar, but the whole page is in German. Alsoit is more of a report than a techinical document. So i could only use the pictures. also he doesnt use the A and B button i think he must use the stat adn select button.

My main question is how do i wire the buttons on the mp3 circuit board on to the NES pad circuit board so i can use the original buttons or is there a way to wire in different buttons underneath the NES ones?

and also how would i install a recharageable battery as aposed to a replaceable that will charge off the USB cable?

cheers

Btw., it is beyond me why some of the Slashdot folks are calling this a fake. All I did was disassemble an ordinary USB MP3 stick (a SHE MP-101 BD, to be exact), cut the NES controllers PCB to size, and wire the buttons to the MP3 players button contacts. The holes for the headphones and USB connector where indeed done using a dremel tool. This is of course not wizardry, but I still think its pretty cool to have a custom player like that. If you don't like it, don't read it.
