Mame: 2nd Button not working - neither on GPIO nor on Keyboard

[Ingo Werstler]

I'm trying to run a few old games which need 2 or 3 buttons. In Emulation station everything is fine, but in any emulator, the secondary button is not recognized, e.g. in Ghosts'n'Goblins I can't jump. Or in Nemesis I can't shoot rockets. The third button is recognized again, so e.g. in Nemesis I can select power ups.

I first though I might not have the right wiring to the GPIO pins but it's the same with the keyboard. Pressing "X" has no effect in any game.

I also checked with jstest, everything is working fine.

Any ideas what I am doing wrong?

recalbox 4.0.0.b5

Just to be sure there's nothing wrong with my setup I just tried Gradius III for the SNES and there all 3 buttons are working perfectly.

We don't handle the keyboard, so it's not a good reference

Could you try ssh-ing to your pi and run evtest for each controller ?

all 3 buttons respond:

not west ?

[Ingo Werstler]

I tried with several connections to the GPIO pins, none worked. Which GPIO pin relates to west?

here again with the joystick output:

no change, in Mame, the second button does not react

[Ingo Werstler]

Seems it is an issue with Mame 0.78, I got some ROMS for 0.161 and with FBA libretro all buttons work.

[Substring]

i'd rather think you didn't check your romset with clrmamepro

[Ingo Werstler]

@subs I downloaded the full 0.78 romset and used it with Mame so I did not expect I have to check it if it's the right romset already. I will do a clrmamepro check and let you know.
