WinUAELoader second player input problem

[burianico]

Hi, i have an input problem with WinUAELoaer (i use it with Maximus Arcade and all other emulators work well). When i use second player, all buttons work well except fire button. I have four fire button and even if i assign one of them, nobody work. WinUAELoader assigns another button (coin 1 button) for second player fire button (in the settings assignment is correct). How can i solve it? Thanks!

P.S. I use a keyhack and my WinUAELoader input setting is keyboardA and keyboardB.
