1.take the little mofo apart 2./pin1+/pin2-/ hook up an (9v battery clip or 6AA clips you could take it from a gamegear solder that on there accordingly  3.Plug in A/v hook ups to Tv test it
4.plug a/v hook ups it to screen wether it be hhtv which im useing cause we had one al ready or a psone screen which is what ill use for my next portable 5.Encase the Monster 6.i suggest put a handle on it for toteageablitynessosity(haha fake words are fun kids) 7.Put in your favorite Cart or Card game personaly(Cart)Afterburner (Card)Ghost house 8.Enjoy hours of Jetpilot fun ^_^ LPC for life Nesdude |
| Submitted by NiN^_^NiN: The sms 2 is the best for maing a sms portable cause the board is small and square but this only has RF on it so here is the mod for getting AV out :). Also the sms2 uses the 7805 dc converter so this is the same power requirments as the snes :)
To get to the board inside the sms2 you have to remove 5 screws on the bottom of the sms2. Then remove the top of the RF shield, with about 7 screws. Now we have to locate and solder a wire to the closest pin to the RF of R21. R21 is a resistor near the RF modulator this is the Composite Video out. When you have soldered the wire to the top pin of R21 solder the other end to a 25 Ohm Resistor then to a 220uF capacitor. Add any plug you like to this as this will hook onto the LCD so either solder it directly to the LCD or make a jack out of it whichever u want. Now to locate the audio we have to find C31, C31 is between the cart slot and the Sony chip. Solder a wire to the closest pin to the RF of C31. Then solder the other end to a 10uF capacitor and you now have audio out. Add any plug you like to this as this will hook onto the LCD so either solder it directly to the LCD or make a jack out of it whichever u want. If you are going to use RCA plugs attach the ground wire from each of the RCA plugs common connector to GROUND on the circuit board. The best place for this is the silver strip along the outside of the board. Here is a picture of the Master system 2 board (Please note not all boards will look the same but they are very simular just a few differences) The red dot = Audio The yellow dot = Video |
