Super Donkey Kong Board
The above picture is from my Super Donkey Kong cartridge. As you can see, there is very little to it- Just a circuit board
with what appears to be 3 spots of candle-wax on it. However, the "wax" is really black epoxy, and it is there to protect
the fragile silicon chips which have been directly bonded to the PC board!
Why go through all this trouble? Easy. It's cheap! This is the cheapest way to make thousands of cartridges with a minimal
of cost, since there's no soldering involved, and the chips are machine-placed directly onto the board so there's no labour
cost to install them. Unfortunately, this makes it very difficult indeed to reverse-engineer the cartridge to dump the game and
get it running on an emulator.
