This emu isn't working correctly anymore.

From the launcher, if I select play or restart, nothing happens.

I think there's a paused screen underneath it.

In Xterm I've done:
killall drnoksnes
killall drnoksnes_startup
killall drnoksnes_startup.launch

I get a black screen for about a minute then I get the desktop back.

Even after doing this and hard resetting the tablet, this emu will still not start a game.

Is there some other process or file that needs to be killed off?

Thanks.
