Like i did with my first one i will install a LCD and change the battery led, also i will be showing you how to do the SMS Mod (Sega Master System Mod) that lets you play Sega Master System games and how to make a switchless Region Mod.
Keep in mind that some LCDs dont work because they have shitty or wrong resolution and/or handle signals the wrong way, some interpolate and distort the nomads signal. i had good luck with 3,5" LCD (480x234) in the 40 euro price range.
You just need to unplug the old LCD on the side of the pcb, the flat cable that connects directly to the pcb has to be removed, this can be done by knife, soldering iron or pure brutality (choose whatever suits you best).
Double check that there are no cross connections after removing the old LCD.
Throw the old screen away, you wont be needing it anymore (and you wont ever miss it, because your new one will rock!)
Lets start of with some pics of the LCD Mod (those are a little better than the last ones).
|first testing the LCD wiring|
|everything is working fine|
|connection points for video signal and ground|
|power supply connection|
now that we have a new LCD lets mod our Nomad a little more, i didnt find good pictures or information on the SMS Mod on the internet so i decided to make some for you guys.
|connect to asic pin 45 (the pin has a small white dot in front, easy to find)|
|other end of the cable goes to pin B30 of the socket (back row)|
Ok starting to get interesting, now that we have done the SMS Mod, lets jump right to the region mod. This mod will allow you to simply change region from US to JAP by simply holding down the mode button of your nomad while starting the game.
|on the same pcb look out for JP1/JP2 - cut the trace that connects JP1 points|
with a cutter knife and solder a cable to one of the middle points
|the other end of the cable goes to the middle pin of this connector (mode button)|
|mod works - you can now simply change the region of your nomad|
so enough for today, stay tuned for more modding soon!
