How to change the COIN BUTTON on FBA-XXX Pro 1.28?

[Cospefogo]

Gentleman,

 

I am eager to play many games of FBA-XXX Pro 1.28 using my Saturn pad

but I feel my hands tied! I can't INSERT COINS because the Saturn pad does

not have a equivalent button for BACK!

 

I went inside FBA-XXX options and changed the coin button in the

SPECIAL MAPPINGS setting but the emulator ignores my changes completely.

 

I even tried to edit manually the INI file and got no results.

There is no way to change the coin button? Is this true?

 

Please, I beg... Anyone passed thru this already?

Best regards,

Cospefogo.
