GroovyArcade emulators config

[safx]

Hi,

I have been using an Arcade machine with JAMMA and J-PAC converter for a couple of years with GroovyArcade installed.
Worked like a charm until i lost the button COIN1 due to powersupply failure (the arcade PSU) that provides the 12V to the coin button.
While i dont replace my PSU, i re mapped my COIN button within MAME to another button, no problem there.
I tried to do the same within the GENESIS emulator, and mess it up completly. I now have no control whatsoever, buttons are all missmatched.

Can anyone help me to RESET the emulator config for SNES, GENESIS, MasterSystem....that comes with GroovyArcade?
I am using all default, never had to config a thing, just installed GroovyArcade and dropped ROMs, it all worked. So i dont know where to start.

Thank you

So i found that it was mednafen the emulator for GENESIS, and deleted the file for the configurations, hoping to reset things.

They did, but now display is completly off, i see only 20% of the screen so resolution must be adjusted.

Does anyone know how can i get the original .cfg file for the Mednafen ?
Thnks

Closed. I fetched the original mednafen groovy file from the CD and it just worked.
