Im 10 years old and Ive been wanting to make a portable for soooooooooooooo long.
Now I can! But I need help....
I am going to use this
But I dont know how to wire it,AND I dont know which screen Im going to use....

Im trying to keep it simplist and cheapest....

If you're wanting to stay simple, a better bet would be to use a Retro-bit system. It's already got a cart connector on it, and it's a NOAC...plus, it's compatibility is much better than one of those beasts. Not to mention it'll require a lot less wiring too for power and controllers.

Plus, they're pretty cheap. One won't run ya much more than 25-30 bucks shipped (if you order one online...)

This HAS a cartridge conntector.And a built-in controller and battery pack. Its plug and play..........so less wireing.

And Banditpaw1 made a portable with this......and it took him 1 hour and a half to make it...
And I found 1 for 30 dollars on ioffer.

Well, it has a 60 pin connector so there will be a LOT more wiring to do.
