Below you will find links to my Youtube Channel , a PDF procedures guide and also to a Zip archive which includes my schematic design & PCB layout.

The STIGsGameRoom Channel Talks about My 512Kb GG Prototype.

I want to personally Thank Memeber "Snow_Cat" from the benheck.com forums for his amazing work with the Cadsoft Eagle software.

Snow_Cat this would never have happened without your custom SEGA component Library. Snow_Cat you are awesome buddy and fantastic work once again!!

 

Snow_Cat's SEGA Library file (Used with Cadsoft Eagle schematic design software) includes the component layout for the Game Gear cartridge edge and also the layout for many of the SEGA Mapper chips.

Here is a Link to Snow_Cat's Website: http://meow-snow.blogspot.com/

 

Screen capture images below are for previewing purposes only. (Use the provided Cadsoft Eagle files from the link above to print your PCB layout for etching).

 

 

-=My design fully implemented using an SMS Cartridge=-

Now there is another alternative to etching your own PCB as shown above. It involves performing a MOD to a classic SMS cartridge PCB.

This is the project I have laid out "Step by Step" in the instructional videos and also in my PDF guide. I believe this will be the option of choice for most of you.

Reason being, it is a much more compact design in comparison to my prototype circuit board shown above.

 

 

Hopefully the information I have posted here will help you all succeed in building your very own 512KB SEGA Game Gear Flash Cartridges.

 

Kind Regards,

Gerry O'Brien
