So I basically have stripped my N64 down to the motherboard! I've connected a PTH8080 and relocated the cartridge! All I need to do Is connect the lcd once it comes ! However, before that comes I would like to comment my n64 to a display to make sure everything is working just so that in case something blown, I can order it ASAP (so I don't double my wait)! However, I torn off the port for the composite so I was wondering, can I strip a pair of cables (yellow,red, white) and solder them into the board according to whatever layout I would of needed when soldering regular cable to mini 4" LCD? I just want to do it to make sure all connections are perfect and everything running smooth ! Is it possible? Or do I need some special equipment ( as in pcb or resistors, etc)
Hooking the n64 to a TV for troubleshooting?

Sure you can, the av port is just the pins relocated so you can plug a cable without soldering it. So if you cut the port and you strip the cable, you can just solder the video, audio right and audio left, and the ground cables to the right pins and it will works fine. And you can do it with any video cable, on my portable the av port is a playstation one and I connect it with my Ps2 cable!

Okay great i will try that as soon as possible also curiosity. i know this should go into another thread but i rather ask here. Can i simply get 3 4V batteries and hook it up as the power source for the nintendo 64? I don't need it to be perfect nor do i need it to be long lasting power. I just want to use it to test and make it work. I'm only asking since i kinda ripped all the ports (Only the power switch, AV and power Port from the motherboar)! Accidently. lol ! Can i do that? What would be the risks if i do that?

Yeah sure, technically, we use around 7.4v batteries because it's the good voltage for the screen and it does work for the n64. so if you have 3.4v batteries, solder two of them in series (which means You connect the + of one with the - of the other than the + and the - remaining connects to the circuit) will get you 7.2v, which is enough. Later you can solder two of these pack in parallel so you double your power time. Be sure that the batteries have a protection circuit, because if it doesn't, it will charge until it explodes because they don't have limit. The better way to do that, if you're not to familiar with portables and things is to buy camera batteries, like canon. I'm not sure it does have a protection circuit but the charger does, so it's the same at the end.(Plus these batteries are already 7.4v)
The problem is that you will have to do your 3.3v line already, because you cut the port. Look in the n64 mega-sticky, for the how to get 3.3v topic. You will need some electronic, but it's not that hard to do, just be sure that you really output 3.3v for the line, if you output too much, your n64 will be fried.
And for the power switch you just cut, Just put a on/off switch at the beginning of your circuit( on the positive cable, between the batterie and the n64) and solder the pins of the original power switch together following this instruction:
Under the board, where the power switch was, you have 8 pins with numbers. Just solder 1-2 together, then 3-4, 5-6 and 7-8. You can solder them from the top of the board too, doesn't change anything. That way, the n64 will always be powered on, but you can cut the power from the batterie with the switch you soldered just before.

I understand it much clearer now ! I will look into tht as soon as possible!supersonic_32

No prob, don't hesitate if you have other questions, making a portable for the first time can be really confusing hahaha
