Re: I provide Sega Nomad screen, battery, & region mods

The reset mod is another handy mod to add to these as well. Had a cart that requires reset to be pressed to select 1 of 5 games. A few cheap parts and fairly easy to do.

Re: Replacing the Nomad screen

With regards to getting the right screen, if you go on ebay, do NOT take the sellers word as gospel. I specifically asked the seller if it was a red guard branded monitor (they had a red guard box in the back ground...or they could have pinched the pics from elsewhere). When I got the screen here an...

Re: Handheld to Console?

The resolution is the same with the GG's with the image only taking up 1/2-3/4 of the screen. The board allows for composite, s-video and RGB, I was happy enough with composite on this one. I have another 2 boards from viletim, but just need to find time to do them lol!

Re: Handheld to Console?

Kind of like this? This is my GG I have modded quite some time ago. It uses a viletim video out board, 2 player controller port pinched from a dead MD2 and the cartridge slot has been relocated. Both controller ports work, player one is simply tapped off the GG's contacts and player teo is taken fro...

Re: Replacing the Nomad screen

The battery draw now for the Nomad and screen is around 250mA. With the original screen it was around 360mA. I am using a infolithium 7.4v 2000mA battery to run it. So I get around 8 hours . While I got the same with my stock Nomad (360mA) with the LCD screen I used it now draws 460mA. I used a dif...

Re: replacing the internal battery

Did the same a while ago and sent a guide to mmmonkey to put on his site. Note the charge voltage anything above 3v wouldn't be the key. With this battery you need to follow the original instructions ie: turn it on every 1.5-2 weeks to keep the charge up. http://www.mmmonkey.co.uk/console/downloads/...

Re: Game Gear with DS backlight problem: what voltage do I need?

Update, I used a DSi backlight as it is bigger, so no faint outlines on the outer edge. Requires 15v to work though.

Re: Game Gear with DS backlight problem: what voltage do I need?

Yes I have a multi-meter. I have done a quick write up on Sega-16. I just used a DC DC converter to give the backlight it's own power source. Take a pic of the area you want to know about. The model I used was single ASIC.

Re: Game Gear with DS backlight problem: what voltage do I need?

You need 12v. I have just done this today, works well. Not as bright and the colours aren't as vivid, but ok. I used a LM2577 DC DC step up module to do this.
