Start/Stop Button + GPIO 4-player Controls (Gamecon Driver)

[BornDead]

Re: Start/Stop Button + GPIO Controls
I´m building a Recalbox inside an old NES case with two original snes ports and two original nes ports and would like to be able to use the original power and reset buttons. I have already set up the controllers and now I would like to add the buttons.

Would it be possible to use 4-player gamecon when using Start/Stop reset and led?

There would be a conflict on pin03 and pin05
Player 5 and reset pin on the same GPIO pin. Player 6 and power pin on the same GPIO pin.

The two I´m talking about are these:

@borndead You can edit the power script and change pins

Thank you that would be perfect. Where do I find the script file to edit?
What pins could I change to?

@borndead I din't know which pins would ve free once you configured what you need. The script sgould be in /recalbox/scripts

I tried GPIO13 and GPIO19. Reset and power off is working, but power on is not working.

I tried changing back rpi-pin356-power.py to original pins and rewired, then reset, power off and power on is working. Must be something special with pin5 (GPIO3).
Do you know anything about changing the pins of player 5 and 6 on the Gamecon Driver?

[Substring]

@borndead That would require rewriting the driver itself

@substring
That´s what I ended up doing, after a lot of trying I successfully got what I wanted by editing gamecon_gpio_rpi.c and rebuilding the driver.
So now I have 4 gamecon gpio controllers, POWER, RESET and LED!

• PIN01 | 5V
• PIN06 | GROUND
• PIN19 | CLOCK
• PIN23 | LATCH
• PIN07 | DATA3 (NES1)
• PIN26 | DATA4 (NES2)
• PIN29 | DATA5 (SNES1)
• PIN31 | DATA6 (SNES2)

The code replace in gamecon_gpio_rpi.c:

/* GPIO pins 0, 1, 4, 7, 29, 31 */
static const int gc_status_bit[] = { 0x01, 0x02, 0x10, 0x80, 0x20, 0x40 };
static const int gc_gpio_ids[] = { 0, 1, 4, 7, 29, 31 };

Sorry for reliving this issue, but I could not reach the solution you explain.
I have the same problem, I want to connect 4 controls (2 snes and 2 nes) and the power off and reset buttons.
The truth is that I don't know how to rebuild the driver.
In this link is version 1.4 of the driver, it is easier to modify the pins, but my problem is in reinstalling the driver
