NES Flash cart here.
Uses compact flash though, so might be hard to get teh right memory for.
I don't like the design of that one or the FC mobile.
Overall its ok, but that D-pad design with the gap in the middle is a big pain for me.
That NES controller one looks awesome, but sadly is most likely a fake.
I know I've seen better ones around somewhere, but I can't seem to find any.
Ah, the Sega No Mad. I remember that.
A friend gave me his once and then I gave it to another friend who wanted it.
I think he got it working, but it was a fun thing.
Playing Sonic 3 and Knuckles with a real cart is a pain though xD (Always reset the game if you moved too much)
Overall I think you are better off with emulators on an NDS/PSP/GBA and the like.
Plus its usually not that hard to transfer save files between those emulators and say one on a home console like the Wii.
