and those wires, are they piggy fixes to bugs in the card?

If I am not mistaken these wires are there as the pcb could not be routed completely and these are necessary jumper wires.
As the 2.x is a complex schematic to put it on such a small pcb. It is really a piece of art sinfox created.
I really appreciate his design as I also tried to create this version on a pcb and that is not easy. Especially not on a konami size cartridge.

I'm using one of this cart from sinfox and know a bit of the production process. The answer for those tangled jump wires is result of a time difference between the release date of schematics ver 2.1 and ver 2.2 . At the moment of designing and producing of this PCB, the latest version of SD/MMC drive was ver. 2.1 as you can see printed letter "v2.1" at the bottom of PCB in the first picture. By the time to sell those PCB, everyone preordered products wanted to have newer version 2.2 that has two SD sockets and FAT16 function. So manufacturer "MODed" on his own product .^o^ But who cares? Inside the small and stout KONAMI case, it's flawless.

Cool product!

Any plans for production/ distribution in Europe?

There are some people here that can find new SCC chips and new cartridge-housings, and have experience with building /distributing hardware....

Hi Bastiaan

I have plans to distribute my product(MMC Ver.2) to Europe or other regions.
I used KONAMI SCC ROM cartridges to make MMC.
I have interest in your opinion to find new SCC chips and cartridge-housings.
If you have some projects about that, give me information definitely by E-mail.
