Per the homepage:
"Finally got around to releasing the first version of my Discrete Integrated Circuit Emulator, DICE. This is a very early release and hasn't been tested fully, so there may be some bugs still. So far only Pong is supported, hopefully more games will be added in the future...

Controls
5 - Insert Coin
Up,Down - Move Player 1 Paddle
A,Z - Move Player 2 Paddle
Esc - Quit

Future versions will have customizable controls, but right now you'll have to edit the source code if you want to change the controls, sorry.

System Requirements
Since it's simulating every single chip separately, it's very slow... Probably about a 3-4 GHz cpu would get it running full speed. It runs at about 20-25 fps on my 2.2 GHz Athlon XP".
