Finished 3 out of 4 initial firmwares for AVeRCADE. If you take into account the bootloader then it's 4 out of 5.

• Digital Stick, 14 buttons
• Dual Digital Stick, 5 buttons each
• Dual Analog Stick, 7 button each

The analog axes can be used with digital stick, though. It is only necessary to add one resistor and use the NC contact of one of the microswitches.

It makes me wonder about coding another variation of firmware, using analog axes and 16 buttons.
