Kite Circuit Sword Speed Issues

[Ian]

I just finished building my circuit sword lite, and after playing a little bit on it, I have noticed a speed issue. However, the issue is not of the kind I expected... everything is running fast! It's especially noticeable in Super Mario Brothers and Tetris for NES, and Advance Wars for GBA. Any ideas on a fix? I haven't overclocked my raspberry pi, though I don't know if that would even be much of an issue. Thanks!

Does your sound work (as in tests ok and plays fine)? For some reason I suspect something to do with sound.. it uses USB sound so directing your search around that may help. There shouldn't be anything special about my build, everything is stock other than enabling USB sound.

I've encountered from time to time that the fast forward hotkey is used when it should not be. It's weird, since by default fast forward is turned off, but like I mentioned I have seen it activated even when disabled. In my builds "space" is usually what select is mapped to, so when pressing select it would turn on fast forward. So I just uncomment (#) this line and changed it from space to something unused (found in the retroarch.cfg).

# input_toggle_fast_forward = space

Change to

input_toggle_fast_forward = some unused key

This may not be your issue, but worth checking out. Does it start in fast speed right from the start, or after pressing buttons?
