This system runs off Li-ion batteries which are powerful enough to run the system, and are also rechargeable cells.
With this series of comprehensive videos, you can. The video series has attracted a considerable internet interest to date on the major gaming sites and YouTube, so I thought i'd post this guide onto Instructables too.
If you're looking at making such a system, or another portable for that matter, please join my active forum, where we can hand-hold you through the process and offer help and assistance as and when you need it; it is a very friendly and helpful community:
Here is a video of the final system:
Step 1: Introduction
Making vintage retro console portables into handhelds is a very good hobby to have, you learn new skills, have to do a fair bit of problem solving in the process; and end up with something special that only a few dozen other people have in the world.
Let me show you the principles of making your own Nintendo 64 portable. With these techniques, you can progress to other console systems too as the principles therein are similar to making other systems.
Step 2: Tools You Need for the Project
Step 3: First Things First - Opening Up the N64 Console
Step 4: Removing the Ports and Heatsink Pads
That is what this section is for, to show how to remove the ports and thus "flatten" the board.
Step 5: Relocate the Game Cartridge Port
Step 6: Reducing the Size of the Boards!
Step 7: Powering the System and Wiring Up Audio and Video
Step 8: Cooling the N64 Board
In this video, I experimented with using a copper plate to distribute cooling, however decided in the end that using 4mm high VGA memory chip heat sinks and a small fan provided better cooling and worked better. This was upgraded in future videos.
Step 9: The Official Sony PSone Screen
This video shows opening up the screen, what pins to connect what to, and doing some basic board trimming so it fits better in your casing.
Step 10: Preparing a Pre-made Vacuum Formed Case and Case Preparation
This video showed case preparation from my own moulds I made for vacuum forming. Cutting the vaccum formed case from the wastage, trimming to an even height, sanding it; working out the exact positioning of the screen, controls and buttons; cutting them out to size in preparation for the case front.
Step 11: Securing Case Halves Together and Alternative Cases
Step 12: Making a Cart Slot Holder and Start of Installation!
Step 13: Controllers, Memory and Rumble Packs
Step 14: Multi-function Port
This video is therefore to show how to make such a port; which after all, can then be used for future portables too.
Step 15: Preparing and Installing the Screen
Step 16: Install a D-pad and Buttons and Their Assemblies
Step 17: Install Other Buttons and Method to Stop Them Rotating in Case
Step 18: Test Screen, Install Rumble Motor
Step 19: Wiring Up the Controller!
Step 20: Batteries - Installing Li-ion Cells Into the System
The cells I use are Canon BP-911 / 915 Li-ion cells, they are excellent and have built in battery protection circuit which is necessary to prevent over and under charging.
Step 21: Removing Reset Button, Install Fan to Cool System!
Step 22: Installing Better Heat Sinks, More Install Details, Closing Case, Testing
Please join my forum and have a look at my website for guides and modding information on many other console systems! Details as per sig!
