Question on nes portable

[valguerra]

I want to build a nes portable, that it has all the games already in the portable. I see it done with a nes cartridge. Was wondering what are all the materials need to complete this project? My main goals is to make a nes laptop portable.

thanks

Probably not ALL of the games but a Super Joy 3 is probably something you'll want to get your hands on. Otherwise you'll be looking for a flashcart, which can get expensive.
