PART #4 of 5 ----------------
This is an Instructional video that I've made to show hobbyists how to build a Programmable FLASH cartridge for the Vintage SEGA Game Gear.
This will allow you to execute your own assembly code or custom Game files on the Game Gear itself.
Soldering & De-soldering techniques are shown and I have also provided a 26 page "Step by Step" guide in PDF format for you to download. It contains detailed Procedures and several photographs of the building process for building a compact version of my Flash cartridge. I have also produced a Full schematic and a PCB layout for those of you who have a little more experience in the Electronics field; and wish to etch your own board together.
However, the Procedures I have laid out in the video and in the PDF guide may be more appealing to many of you, due to it's compact design.
I hope you all enjoy this DIY project that I have laid out here for you to try. :)
It was a long haul but such a blast! :)
You can Download all of the required files & documentation off my Website at the link shown below:

(My site is under construction so please excuse the crudity of the layout)
Also, if you're having trouble and want to coordinate with other Hobbyists that are working on Similar GameBoy/Sega Game Gear projects, please join the GAMEBOY ELECTRONICS YAHOO GROUP that I have started up. This is to help everyone with their GAMEBOY/Game Gear related development projects.
