Like I said, it looks horrible. The GP32 screen is not intended to be 'blown up'. On my 20" tv screen, it's horrible quality and looks like how you blow something up in paint.
I'll post a how-to.... (This is how I did it...)
1. Go to
http://www-public.tu-bs.de:8080/~y0018703/...r/gp32_xray.jpg . Look at the bottom of the image, and you'll see the ext. connecter. And then you'll see the little prongs on the top of that ext. connector. It's easier to work from the inside then make a tiny wire that plugs into the outside. Once again, im not certain of the video out connector, I just probed the whole row of connectors by cutting my video cable like so...
Two wires===============Plug
With the plug plugged into the TV, i took one end of the wire and attached it to the ground connector, and i just slowly touched the other connecters with the other end one-by-one until I saw an image on the TV...Once you see an image, memorize the connected you connected it too.
2. OK - now this is the hard part. You have to drill a hole on the right of the ext port, one that is wide enough to house a female video out port. Once you have that hole in the casing, work on the inside so you can fit it in well (I used a glue gun and just made it swim in there until it dried), but don't insulate the connectors, and make sure the case can close. Now, ply a ground wire to the ground prong on the connector, and the other wire to the other prong of the connector. Congrats - now you have a working video out port.
3. Attach a male-male cable to your GP32's video out port and the other end to the TV. Use the headphone port in order to have sound.
Easier way to do it:
1. Order a cable from...

2. Dissect the cable to find the video out wire, and then remember the color of the wire. Attach a male video connected on the end of the cable to the ground and video wires.
3. You're done.
I'm not responsible if you screw up your GP32.
