Hey Ben
You already made a lot of laptops, but I've never seen you make a NES laptop. Here are the 5 things the NES laptop must have:
1. At least 5 hours of battery life : You've never made a laptop that you can use on the bus or on a long flight. Give this one a battery. I think this is possible, because as seen in the "NES in a cartridge", you can make the NES very small so there is a lot of place for a battery.
2. 4:3 Screen: We do it old-school. Use a low resolution screen so that the NES games look the best and not all stretched out.
3. Disable the region lockout chip: more games to choose from is always better
4. Cartridge slot: Create a cartridge slot that doesn't block the screen. Maybe you could make something like the normal NES where you insert the game and then push it down. Also make the label visible but hide the rest of the cartridge in the design.
5. Make it look good: Try to make it light (max 2 kg), thin (max 3 cm) and just awesome. Don't make it look as grey as the normal NES. Use a matt black finish with maybe some LED's or EL wire. Also include a charging cable for EU and US and please don't put the ports in the front. If you're gonna use this on the bus, you don't have too much place and don't make the laptop even longer.
This build should be cheaper than most of your 360 Laptops and I hope that you can make this one for me, because I just don't have the tools and budget to make it myself.
