Im still working on Gameking things when time permits.
Team Europe has also started to dump new Gameking games and up until recently we have had no way to test our dumps.
I have now made a multi game cartridge for the Gameking which can hold 4 128KB size games and are selectable via two dipswitches.

So far all the games we have dumped seem to work just fine although Team Europe has recently dumped an actual multi game which will NOT work on this board.

I realise that there wont be many people in the world that would want one of these but if you do I currently have 4 spare for sale at £10gbp + postage fully assembled with blank flashROM.

Dumping Gameking cartridges

Got my hands on a Gameking with 13 games recently.
The Gameking is a bad handheld device from the East and all the games are a ripoff of something already released.

This little project represents the first attempt at I made at dumping a ROM using the Arduino.
It’s also the first time I used the 74HC4040 to generate the addresses. I used these binary counters because they offer 12 outputs and it only uses 2 outputs from the Arduino. They are also tolerant of both 3.3v and 5v so interfacing with different voltage chips is a lot easier.

On with the dumping.
There is a guy called Brian Provinciano that once had a website that contained a lot of nice information about the Gameking. Fortunately it can still be found here

So armed with the pinout this should be easy right? Nope. The physical cartridge pinout is a 2×30 pin affair and I could not find one. Nothing left to do but desolder the original cartridge connector from the Gameking unit itself.

So now I have everything I need. Time to hook this thing up and test it out.

I had each byte spit out to the serial port and then used my makerom.exe program to create a binary file the log file.
The end result looks pretty decent. I can see the header of the file.

I can also see all the game graphics using Brian’s editing tool available from the link above.
Unfortunately that’s as far as I can go with it for now as there are no emulators available. There is one for the NDS but its worthless in terms on usage.

This was a great project that was pretty easy to build.
