atariboy? case looks good! small as heck screen though?

Yes it is a small screen but maybe the Longhorn Engineer can craft for his AtariBoy, a Super Wide (like here and here) and that will improve it. :lol:

i actually own one of those for my GameGear LOL

New WIP video. And guys there is a new 3.5" screen on its way. Will look "right" with it I promise. By the way the audio amp sounds great and is less than the size of a quarter and cost me $4 to make :roll:

lol

Video doesn't work.
Too bad you aren't using a real atari. I need help making my first portable. Already got an atari.

Yes it does.
There are plenty of guides on this forum to help you with that.

Hmm works now. Must have been down for a couple of minutes.

I'm looking at tutorials right now but I don't know anything about voltage or anything is there a really good tutorial on that?

Did you perhaps order the screen from DealExtreme? *smirk*

You'll have to share some advice! I got someone to send me a modded FB2. I had to see what the heck I was doing work. Now that I have corrected some issues with mine, I'm thinking of moving forward with my project.

The screen I am using is one of those 3.5 inch pustoms (From ebay... hong kong).
I've got 6 AAs wired up to power the screen. When I attach the screen to and FB2 together... the screen dims. The game is still playing in the background, but it dims after a few secs. There is an issue with power... I assume. When the volume is on... if I am playing pitfall, the screen dims when I jump.

I did not do the the LED mod for the screen... but I may need to. Then again I only have 8-9 volts going to the screen. (the fb2 I still had running off of the wall wart... I was just doing a quick test. lol)

Perhaps I need to do a something else? Got any ideas?

Obviously I am watching your project! LOL
