OK, I did that and mapped all the game control types to a generic 4way plus buttons for player 1 and 2. Now, in the lightgun games, its clear that the coin and start are not mapped properly. when you look in paddemul.ini and the module Ini, they have the setups for guilty gear style, sf style, driver, etc. but no "lightgun" key controls to map. lightgun is referenced as a control type for the proper games in the module ini file.
I copied all the controls to the ini for demul 0.5.6 module so that's not the problem.
In the global Rom options for Atomiswave, it has additional tabs labeled atomiswave_jamma 00_1 etc. but I cant find these in the module INI file to edit.
I have had the lightgun games coined up, started and working/shooting in a demul window but now I can't find how to permanently set the coin/start keys for those.
