after removing layers of dust we finally played some good old NES
games today!!

to have even more fun with the box i'm planning to create my custom
cartridge with connectivity to the modern world (USB, CompactFlash or
Ethernet) - just to ease the upload of a cartridge backup.

it will also be able to emulate the known PRG/CHR/RAM pinouts and
memory mappers of the original cartridges.

does anybody know if someone else already did something in that
direction? wouldn't be that much fun with the soldering iron if i'd
waste my time here :)

any help in the project is apreciated.
