guys,
I hope you can help.
I have a hyerspin front end and then use mame .  
My problem started where pressing the p1 fire button would reset the rom.  I made a video here 
Somehow I resolved this issue but now the on screen volume button shows and it also fires at the same time.  I made a video here 
I noticed the "on screen display" was set to use CTRL which is also the same key as FIRE.  I changed that to NONE but now its back to resetting the rom.
Any ideas ?
