Game Gear RGB

id go over it with a scope, and find the points
once you have sync, hook it to a tv through a resistor, and start adding other signals (you will know it when you see it)

I just installed his pcb. Now my gamegear have video out. Just need a 3.5lcd to complete the mod. SMS games display in full screen. Would be nice if the gamegear games display in full screen too.

Nice! Love DD on the MS, so much better than the NES version.

turbokon · 12/10/2012, 04:12 PM

I agree:)

Now can anyone where to the controller pinout so that can added an external controller for player 1? The extension bus on top is for player 2.

omp on Sega16 might know, he's done a fully modded GG with the first version of this board and 2 player compatability.

I just got my board from tim as well but haven't installed it yet though. Very nicely packed, he put the board in an anti-static bag and then packed it all well in a box so it got to me safely. I'm in the US btw and the box he used was big enough to fit multiple boards in without any issues if you guys wanted to do a group order.

Very nice, I've been thinking on and off about making a consolized GG myself as I have two laying around, one of which needs a new cart port. However, I'd ideally stuff everything in a plastic project box as opposed to cramming everything into the GG case, as I want to have controller ports and an 8-pin DIN jack for RGB.

turbokon · 12/11/2012, 08:11 AM

Yeah that's a good idea to stuff everything inside a plastic box. I'm finding the gamegear doesn't have room for an LCD mod. There is just no room to stuff the lcd's pcb. Anybody else have any ideas as to make the LCD mod fit inside the gamegear?

thesteve · 12/11/2012, 12:20 PM

remove the reflector, and the board should fit fine

turbokon · 12/11/2012, 01:01 PM

I did that, the transformer I think on the gamegear is in the way. I might need to trim the lcd's pcb and re-arrange some components.

thesteve · 12/11/2012, 02:03 PM

the transformer should be removed

turbokon · 12/11/2012, 02:39 PM

So that transformers and the blue ceramic cap near by can be removed?

thesteve · 12/11/2012, 03:07 PM

yes, they drive the backlight
lookup backlight mods and most will show them removed

Looks great, how hard of a mod was this (on a scale of 1-10)?

turbokon · 12/11/2012, 08:45 PM

Install the rgb board isn't to hard if you know where the soldering points are. Using Tim warington I would say 3. Here are a couple pics if the LCD mod.

turbokon · 12/12/2012, 11:24 PM

Here is another pic:)

sirhcman · 12/13/2012, 02:40 PM

Is there a way to do the lcd monitor swap and still have the GG games scale to the size of the new display? (sorry total tech noob here)

thesteve · 12/13/2012, 05:38 PM

yes, with a custom LCD controller
most LCD panels do "data good" scaling (supported by the GG LCD controller
would just require a custom programmed microcontroller

Steve I am going to PM you about this stuff!

turbokon · 12/13/2012, 08:56 PM

I would like to know how to do this too!

sirhcman · 12/14/2012, 10:31 AM

turbokon not trying to threadjack but if anyone here can or wants to do a Game Gear monitor swap, programmed controller for scaling, cap swap, and RGB mod (or can push me to a person who can do one) please shoot me a PM!

Thanks!

it will require a simple controller to interface it
the RGB DEN mode will auto scale

Duo_R · 01/02/2013, 04:55 PM

what games will scale and what games won't? Think it is pointless if the games end up looker smaller.

turbokon · 01/02/2013, 07:20 PM

SMS games almost takes up the whole 4:3 aspect ratio area but game gear games doesn't.

Duo_R · 01/03/2013, 09:00 AM

Wow that's pointless my modded Sega Nomad plays SMS full screen...lol

Need more details on the scaler idea

turbokon · 01/03/2013, 01:14 PM

So how did you get the nomad to play SMS games?

Duo_R · 01/03/2013, 10:42 PM

SMS mode - all you do is ground a pin from the cart port to a chip nearby. Very straightforward. All this does is enable SMS. I then use a Mega Everdrive and load SMS roms on it. Not all games work, I recall Ys 1 not working properly, but all the other games I have tried work great. I just added details here on the pins that need to be connected.

Back to topic, it stinks this doesn't go full screen on GG games, Steve have you tried a scaler on this yet?

thesteve · 01/08/2013, 01:42 PM

not yet, but a got a screen to try

please keep us informed, i need to get my monitor replaced and definitely want the image scaled for gg games!
