Parts: about US$ 20 from Digi-Key. (actually, I got a development kit which was a bit more expensive but also has a lot of useless crap on it)

Can we expect other devices for N64 and Game Boy games?
In theory, this should require no more than soldering additional connectors to the little processor who's doing the USB and data handling, and writing a few more lines of code. So, in principle it is possible and to some extent even likely that I (or someone) will extend this towards other systems or even come up with an all-in-one solution covering everything from Atari 2600 to DS
Just to put it more clearly: this is not an emulator! You still need extra software to execute whatever the USB thingie reads out of your cartridge...
Anyway, I shall now call it a day and see if I can make a few photos over the weekend...
Stay tuned!
(and don't forget to donate crappy game carts for further development and testing :-))

You should think about building them and selling them, like DaveC did with his Dpad mod for the GP2X back in the day. You could even put them in those little project cases you can get from Radioshack, so that they don't have a lot of exposed wires and circuits. If you made N64 and Sega Genesis ones, I would definitely buy.

The hardware is simply an AT90USBKey evaluation board by Atmel....

.... hooked to a card edge connector with a whole bunch of wires.

The firmware is built upon the USB Mass Storage example application provided by Atmel, adding the ROM I/O as well as a "virtual" FAT16 (and don't forget the LONG filename taken straight from the cart's name field :-))

i wouldn't recommend announcing you're a pirate (or that you have pirated many times before). i think this falls right on the border of what's allowed and what's not.

"How it's done" - actually, on the hardware side this is really just the development kit plus a huge bunch of cables. Unfortunately, I built the firmware upon a sample application from Atmel, and their license forbids the distribution of the source. (I can still explain what I did, and even spread the binaries, though :-))
To make the whole thing a bit more beautiful (and perhaps put it in a little plastic case), I designed a circuit yesterday that just contains all the essentials on one board. I will do some testing, add more game systems, etc. and once the whole project reaches a state where it can go public, we can think about group-ordering a batch of professional PCBs and parts (almost everything gets a lot cheaper at as few as 25 pieces)
