Gamegear screen

If you're making a portable you probably need something to watch it on. (Unless you want to guess what's happening in the game, but I wouldn't advise that) Anyway, this forum is your "Hacking a pocket TV/screen" one-stop solution. Share your experiences and knowledge here.

Gamegear screen

Post by atrain »

Hi all,
I have a slightly bricked gamegear, and I started looking into what I can do with its screen. It was hard to find any info at all about it, but I discovered that it is actually a citizen UC-295-1NA screen. That would be helpful, if there was documentation anywhere on the internet.

From what I've read about this, it can take composite input directly. I am not sure of the validity of this statement, but I can't prove it without the datasheet.

If anyone here has access to the datasheet, I would really appreciate it!

Gamegears can't be bricked. Only something with some sort of internal ROM can be bricked. I suggest trying to fix the GameGear.

its not totally bricked. Almost every time you turn it on, it will only be a white screen, sometimes black....

Once in a blue moon, it will work correctly for a while, but it always stops working at some point. Unless someone is seriously interested in buying the machine off me to fix, I'd be more interested in using its LCD.

Either way, I know of someone who has about 1/2 of a gamegear left, including the screen, so the datasheet / any known information could be passed on to him as well.

That doesn't mean it's bricked. It just means your cart's contacts are dirty. Get a q tip & some rubbing alcohol & clean your carts.

tried.
I really do not care much for the machine. Fine, I will fix it. But for the other machine: does anyone know the pinouts or have the datasheet?

All I need is some way to connect it to composite or serial. I don't care about backlight, though it would be nice.

Don't work with what though?

actualy, through the link at the bottom of the page, i found lots of info about the citizen UC320. They don't offer any datasheets...

"unfortunatly this is the official word and nobody has figured out how to use it."http://geocities.com/vjkemp/sega/ggtv.htm

thanks anyways. Maybe I'll see if I can get one of those tv carts for cheap.
