@nguyenhaongnam a sf2 cabinet certainly doesn't use analog joystick !

But if you want analog joystick yes you have to use an arduino

@hoangnganvy1993 only thing cleaner I'm aware off would be to pull apart a xbox360 or ps3 controller and reuse the electronics board inside if possible.

also be aware you won't be able to use recalbox at all with just analog joystick, the main interface for selecting games only works with digital pad

hmm even with custom cfg file setting value to 5 no change....
the analog is digital i just dont get it. ive tweaked everything i can think of and more, dead zones etc.. i just dont get it. arch rivals, sinister, after burner, none of these games will play as analog...

@aFriendNamed5 prboom can have its own config file like most of other emulators. Just read the wiki and the recalbox.conf

@torra87 mmmhhhh ... would SDL be guilty here ? i don't think so ... I honnestly don't have any clue for now.

@creaturefactory Yes I think so. It is the same type of joystick... only bigger ;)

@theoldguy probably a deadzone problem

To be clear: The stick IS operating as analog. But the zone of movement where it is analog is very small, kicks in at a relatively high value (presumably at least 4096,4096), and reached 100% input almost immediately with only a very small movement. There is a large area towards the outside of the movement circle, seems like more than half of it, where all movement is at 100% despite not being anywhere near the physical limit of the stick movement. black=no effect grey= effect, engages suddenly at high value, and quickly reaches 100% with very little movement. white=100% effect, reaches 100% well before stick physically reaches edge of range. ^^^ bad ^^^ Modern controller sticks self-centre, so a huge analog deadzone is redundant, and suddenly outputting 100% effect when it's nowhere near 100% of it's physical movement range.. is very tedious.

You must change the nature of the retroarch gamepad in the retroarch configuration.

So does anyone have any info that i can use? I looked into the mk_arcade_joystick_rpi.c file, and saw where it can be altered.. But i'm guessing it's not that easy, and i wouldn't know how to install the modified file anyways I guess i'd have to repack it into a deb file? I may even need more than 16 buttons. Maybe even 18, so i can have a couple buttons for the emulator menu for example. I don't need the 2nd controller, i just need 1 controller with a LOT of buttons and 2 gpio pins.

static const int mk_max_arcade_buttons = 16; // Map of the gpios : up, down, left, right, start, select, a, b, tr, y, x, tl, c, l2, z, r2 static const int mk_arcade_gpio_maps[] = {4, 17, 27, 22, 10, 9, 25, 24, 23, 18, 15, 14, 7, 8, 12, 16 }; // 2nd joystick on the b+ GPIOS up, down, left, right, start, select, a, b static const int mk_arcade_gpio_maps_bplus[] = {11, 5, 6, 13, 19, 26, 21, 20 };

Getting the analog into it using the MCP3002 2 channel ADC is another problem. It would actually be nice if we could get a GPIO controller that has a menu for reconfiguring it, so you can pick and choose the pins you use and for what, and the number of controllers. Edit: The GPIOs listed aren't set, since i think i'll need to switch some out, move some of the joystick 1 buttons to the joystick 2, so i can use the upper GPIOs for the ADC. Not 100% sure which ones will be used though.
