Howdy-
I've got a few different MAMEs & Daphne (version 0.101.22, plus an older one when I run Cliff Hanger) on my cabinet, all controlled with the MaLa front end.
Most games use a pretty standard input control mapping, but I tried doing something a little different for Interstellar & ran into a little problem.
I went into Daphne Loader v2.1.48 & remapped "up" & "down" to be left & right on a secondary joystick, since those controls seem to twist your ship left & right (I suppose the original arcade stick was a twisty-flavored one...). I believe that the rest of the game setups could all be the same (though I have other control preferences that I'd like to use on a few other games...). I have an 8-way stick & a 4-way stick that I wish to use, depending on the game, but using the primary & secondary key assignments lets me cover all those games with both sticks OK.
Looking at the command line that Daphne Loader sends to launch Daphne, I saw that it's not specifying key assignments in the launch command, so I figured that the commands are "embedded" in an ini file or something for each game. The thing is, I can't find such an ini file...
However, after I ran Interstellar from my MaLa launch (which duplicates exactly the command line that Daphne Loader uses), I ran Dragon's Lair & noticed that the up & down commands were still mapped how they were for Interstellar...

So, best as I can tell (in my programmer novice layman's terms), Daphne Loader assigns keys & those keys will "stick" until Daphne Loader runs another game with different key assignments. If I launch multiple Daphne games (with different key assignments), they'll all use whatever key assignments were associated w/ the *last* game that Daphne Loader ran.
Is this assessment correct? If not, how do the key assignments get passed to Daphne?
If so, is there a way to override this & send the key assignments in my command line from MaLa or otherwise "attach" key assignments to each game so that they're preserved when launching from MaLa?
Thank you very much,
