Gameking multi cartridges

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.
