Game Boy Advance Backlit Screen

As always, my younger brother loves to throw new projects at me, in this case, a Gameboy Advance, AGB-001, aka, the one with the useless color screen.  Previously, someone had installed a frontlight, that was way too bright and uneven.  Fortunately, you can install the screen from the Gameboy Advance SP, second generation, with a little plastic modification.  There are many sites that detail how to do it yourself, or I can do it for you, *wink*.

Thankfully, I actually have an x-y milling setup in my workshop, so modifying the housing was straightforward, but I don’t envy people who have to do it with nippers and a razor, yikes.  The results are pretty amazing, so much so, I purchased a GBA a few days ago to do the mod myself.  I like the form factor a lot and want to be able to play the gamut of Game Boy games on an amazing screen.  I posted a video above, on my own personal machine.

I am tempted to add a pre-modded GBA as a standard product.  Let me know in the comments if there is any interest.

 

Atari 5200

I was successfully able to mod an Atari 5200, 4 port, original console. It was quite a challenge, but what I did discover is there are not many resources out there for modding the 5200. Below is a schematic of the circuit that worked for me:

For the mod I did, I went with composite out, but you can just as easily do S-Video out. This schematic is a mashup of http://www.gamesx.com/wiki/doku.php?id=av:5200_s-video_mod and http://atariage.com/forums/topic/193474-better-atari-5200-s-video-mod/

This version of the 5200 video out differs in one respect, I replaced the fixed 2K Ohm resistor on the Chroma line and replaced it with a 10K, 20 turn potentiometer. I found I was able to adjust this pot until noise was more or less eliminated from the composite video. It may not be needed with S-Video. Another adjustment is on the 5200 board. There is a large potentiometer in the lower right quadrant that is the color adjust. I loaded up Ballblazer and adjusted the colors to what I thought looked most accurate.

The connection points are as follows:

Thanks Atari Age!

My next project is to reverse engineer the 5200 controller to allow for the use of modern potentiometer based control sticks.
Here is the analog stick:
