F2 is always service on Galaga?

(1/1)

Sonny_Jim:
I've noticed a strange bug/issue with galaga (or any other games with service mode on the dip switch).

I'd like to use the F2 as pause, as I've already got a switch wired up to F2 I'm too lazy to drag the cab out and put another wire in.  I've disabled every control I can see for 'Service' and set pause to be F2.

Most games this works fine, but if I press F2 in a game that has a DIP switch that says "Service", groovymame oh-so-helpfully pauses the game AND toggles the DIP switch, so it goes into service mode.

I am using the Groovyarcade distro and for the life of me I cannot see where the key configs for groovymame are stored, can someone enlighten me?  I'm guessing the keycode for DIP switch service is hidden in a config file and not accessible from the menus.

The easy option would be to put another wire on the J-Pac but I'd rather not have to do my back in moving the cab again!

Here you can fond some information, they talk about an old version of mame, but it should work also on recent versions.

:dunno
What should work?  I see no resolution there, only confirmation that it's hard mapped to F2?

Ansa89:
If the game has a dip-switch for service mode, you have to recompile mame with modified "src/emu/ioport.c" (look at line 4870 or around that).
(Hoping that "src/emu/ioport.c" is the new name of "src/emu/inptport.c").

Gray_Area:
F2 is service mode for all games in MAME.  (Hint: read about MAME.)
