Inputs not responding when using GPIO arcade buttons on Maldita Castilla (port game) in RetroPie #27

Hi there, First of all, I don't know if this issue would fit here, so if not, feel free to close it.

I've installed a port by YoYo Games of the amazing game Maldita Castilla for the Raspberry Pi.

I've followed these instructions and it's working perfectly, but only when using a keyboard, not when pressing the GPIO arcade buttons.

Do you know why that might be? The other ports that come bundled with RetroPie work flawlessly. And also all the emulators.

Thanks!

See the retrogame README for directions on setting up a udev rule, see if that helps.

Thanks! I think I already did that, but I'll check again and I'll let you know. The thing is that's only happening with that particular game, Maldita Castilla.

HI there, it's been a while. I set up udev rule following the instructions and it still doesn't work.

The strange thing here is that this game works with a keyboard, and for what I understand, what this utility does is convert the GPIO buttons into key strokes, so it should work, but it doesn't :(

There are multiple ways of both generating and capturing keyboard events in Linux. It appears this game and retrogame are using two mutually incompatible methods, and without information on how the former is operating, can't resolve this.

retrogame was designed to be paired with RetroPie. If it happens to work with other things, that's "cake," but if not, it's not something I can scramble to fix.

I'd suggest trying out the latest retrogame (the udev stuff was cleaned up a little) and making a configuration file to match the game's keyboard input...but if that doesn't work, only option then is connecting a USB keyboard when you want to use this game.
