I still have this issue, but I think I'm the only one in the known universe. I'm using Paul Willingham's PSX-C64 adapter that allows the use and re-mapping of buttons on a PS2 controller on a Commodore/Atari found here: http://www.ebay.ie/itm/222492872670
And here's the manual:

I love using a PS2 controller thumbstick with my C64 and have separate buttons for up (for jumping games), down (for ducking), fire, and rapid fire. I use this controller with Zeta Wing, Soul Force, and Neutron without issue.
But when I use this adapter with Briley, it seems like the "back" function is constantly being activated. On the main menu, when I try and select "New Game" or "Continue", it goes to the next screen then immediately sends me right back to the main menu.
During a game, if I plug the adapter in, it appears as if I'm just holding down the fire button, as it goes into the options menu, then right out, then back in, then right out, etc.
When I run a joystick tester program, I don't see the firebutton being pressed repeatedly.
Could this be some sort of firebutton polling issue? Again, this controller setup works just fine with your other games. I really love my controller setup (it took me a long time to get something I really liked) and want to use it with Briley.
Maybe allow an option that only allows "back" from the keyboard? I'd prefer to use a button like everyone else, but if I can't get that work, then I can live with the keyboard route.
Any help is greatly appreciated.
