For gaming it doesn't need to be correctly wired for "handshaking", only three wires are enough for Stunt Car Racer, Lotus2, Super Skidmarks etc.

In the simplest form it's easy to make yourself if you don't find a suitable cable anywhere. Just two female 25-pin d-sub connectors, cross connect pins 2 and 3 (data), and straight connection for the pin 7 (ground).

Here's an another diagram with the full handshaking, which is mostly needed with different kinds of file transfer protocols: http://www.hardwarebook.info/Nullmodem_(25-25)
