I would do something like I-pac do, for example pushing together 1P-start and 2P-start get the shifted function of 2P-start button, for example 1P-coin...
Shifted functions on the miniArcade 2.0 work differently than shifted functions on the IPac.
If you have to have shifted functions that work exactly like an IPac, get an IPac.
I thought to wire the 1P-start switch to both F7 and D7 pin but i don't think this would work
Correct. That will
not make it work like an IPac.
With that setup, if you press and hold F7/D7, it will immediately send the shifted output for F7.
If you press another button with a shifted function before you release F7, it will send the shifted output for that port.
- Two keystrokes from miniArcade 2.0. (F7 shifted + second port shifted)
- One keystroke from an IPac. (second port shifted)
i thought also to use some diodes
Diodes would work if you were adding a dedicated admin button for a shifted function to the control panel, but you mentioned not wanting to add buttons.
