144 LED Games Console Project

Give me the word and I'll go ahead.

If you're waiting for the word from me, then go ahead
If SMD makes the LEDs cheaper that's something to think about.
I paid about $30 Au in LEDs per unit, and they were fairly ordinary LEDs.

The only consideration I can think of is the joystick buttons should be
arranged like a joystick, and remember you have to turn the unit vertical to play tetris,
so I don't think the joystick can be ideally located for both games.
I've posted an image of how I'd try to lay it out now so the joystick could be
used for both games without wiring it seperately.

It also might be an idea to add the EEPROM as it is in the first schematic.
If you're using a 40 pin DIP for the 16F877 then the ICSP header is optional.

In the schematic I have given, two of the direction buttons switch pins to gnd,
and the other two switch pins to +5V. This could be changed to make
the buttons all uniform (and the software altered), or left as is.
