Game controls don't respond correctly, can't open remapping window

[GoogleCodeExporter]

What steps will reproduce the problem?
I get different results depending on the game. Paperboy turns hard left and 
crashes. On nemesis and pacman the joystick won't respond to being pushed 
downwards. I've tried pushing the two red buttons on the icade (and other 
combinations) in the game but can't open utility to remap the controls. The 
same happens when I use the screen controls too so it's a software not hardware 
issue.

What version of the product are you using? On what operating system?
latest imame4all with latest ipad os.

Please provide any additional information below.

It all worked fine at first. I suspect i accidently changed a setting, but 
can't open the utility to change it.

Ok, worked out how to solve this. If you unistall and reinstall imame4all the 
problem persists. So basically you have to go into the imame4all folder and 
delete all the config files. I deleted everything in there basically and then 
uninstalled and then reinstalled imame4all and then loaded all my roms back on 
and restarted my ipad. Voila, it did the trick.

Note to Dev: i made a mistake without realising and it was quite difficult to 
put right. Perhaps include a reset keys option in the options menu rather than 
something offered in exclusively in game?
