Joystick debouncing about adafruit-retrogame HOT 7 CLOSED

Are you using the 8-way stick from Adafruit or did you buy a more industry common stick? If you are using a more common stick it sounds like you aren't grounded properly or have a stick with NC (normal closed) and have used those, a direction held should keep the pin active if using Adafruits stick or a proper Normal Open stick.

This is the directional button I will be using: http://www.mouser.com/ProductDetail/ALPS/SKQUCAA010/?qs=N5Jky1br14PIN8L1H/2niA==

Right now im just testing with a simple tactile switch but its the same concept as the directional switch.
This is how I have the button wired currently: http://www.cl.cam.ac.uk/projects/raspberrypi/tutorials/turing-machine/pins_1110.jpg

Will a tactile switch just not work like that?

I think what you're asking for is auto-repeat; this is an entirely different animal than debouncing.

retrogame issues individual key press & key release events matched to GPIO input. Auto-repeat is purposefully not done as this may interfere with emulated games' own handling of held buttons (which may or may not repeat, and if so, at a rate specifically defined by the game).

Looked into it. The good news is that MAME distinguishes between key PRESS and key REPEAT events (the latter are disregarded; this is a GOOD thing for accurate game emulation). I've updated the retrogame code to issue key repeat events when controls are held, making the gamera menu easier to navigate without affecting game play (and doesn't substantially increase CPU load).

I tried out the new code and the repeat part works great but its backwards for my button, when I press down and let go it keeps scrolling down until I either press and hold the button again or pull the resistor. When I put the resistor back it keeps scrolling.

I dont mean for you to change the code for me haha but thank you very much! Is there something small I can change for my case to make this work right?

Shouldn't need a resistor.
Pin -> button -> GND

Thank you works great!
