Nice! Does it support physical cartridges?
No, physical cartridges are not supported, the de0-nano has 3.3 volt I/O interface, the cartridges I suppose 5V.
Is necessary level translator, is not impossible but my shield do not have this kind of interface, may be using the 2nd I/O connector of de0 nano witha dedicated board.

I'm new to electornics in general and just discovered FPGA because of this article. I've found it very interesting and got myself a DE0 Nano. So far, I have the VGA and SDCard working. However, I couldn't complete the PS2 interface yet. Does anyone knows the values for the 4 diodes on the schematics at http://caro.su/msx/ocm_de0n.htm ?
Thanks!
Those are BAT54S.
