parts list.....
1) Source a NDS (ideally a broken or faulty unit)... this can be sourced from a local seller (game store) or off eBay....
(you also could by a replacement housing and a motherboard...from somewhere like Aliexpress or even eBay)

2) 3.2" ili9341 SPI LCD
https://www.aliexpress.com/item/3-2-inc ... 4c4du0C3Oz
I also used these connectors to connect the screen to the RPi
(but you could wire the screen up, but you'll have more wires to deal with)

3) 3.7v LiPo battery (the one I used was dependent on the amount of space i made inside the housing using a rotary tool)
https://www.aliexpress.com/item/3-7V-35 ... 80882f48ac
(before ordering a battery make sure you can actually fit it into the housing)
4) Power Module
I used the generic power module used in most GBZ build
(commonly known on this forum as the Banggood PSU)
https://www.aliexpress.com/item/Mobile- ... 4c4dien7hn
but i would now recommend (and would use if building again)
Helder Retro PSU
https://sudomod.com/forum/viewtopic.php?f=38&t=6421
it may seem like overkill, but its will actually provide other functions that would really suit the build in a very small form factor
(like a on-screen battery monitor, safe shutdown, ability to add a analog joystick and easy enabling of GPIO controls)
5) Sound
USB sound card

Amp
https://www.aliexpress.com/item/1PCS-Mi ... 2eb0784232
Speakers
I used 2 mini VECO speakers (which can be found in laptops)
but the Original NDS speakers can be used....
or a set of Wii U speakers will also be a good option

Volume wheel

Headphone Socket

6) This is an obvious one, but a Raspberry Pi
I used a Raspberry Pi Zero W
https://thepihut.com/products/raspberry-pi-zero-w
but with the new RPi3 A+ just recently being release, I would also consider this (providing everything is trimmed off the board)
