Hi, so I came across a weird issue with Snow Bros 2. This game has by default F2 set to Service Mode, which is normal. But pressing F1 also opens Service Mode. I notice in the DIP Switches menu in MAME it has a DIP switch labelled "Test Mode" that turns on when I press F1.
Problem is, I have F1 bound to Player 3 Start, so every time the third player tries to start a game, it resets the system and goes into Service Mode. I went through all of MAME's controls to see what is causing F1 to trigger this and have found absolutely nothing. How do I switch this? Is F1 just hardwired to that specific button no matter what?
I really don't want to remap the Player 3 button across the board because I'm using my MAME cab to emulate other systems too and F1 is used for other emulators.
