Title: Problem assigning player's 2nd button to double as that player's "start"
Post by: spystyle on December 20, 2009, 01:11:38 pm

Hello from Maine,

Well I restored a converted 1985 Atari Gauntlet :) Kinda, then MAME'd it.

It was very beat up but bondo and semi-gloss black paint can help a lot :)

Also the sideart had to be restored with markers (it was painted over and when the paint was removed it was faded)

If you recall the Gauntlet control panel each player has two buttons, first is "fire, second is "magic / start". So the second button does double duty.

In MAME I set the player's second button to double as that player's "start", it accepts it in menu, but it doesn't work.

I had to change it so "button one" doubled as "start", and it works perfectly.

Am I am a bug or did I find a bug?

I don't have another (finished) arcade machine  at the moment to test this out on ...

I think this problem may be specific to the Gauntlet rom (ironically) ...

Thanks :)
Craig

p.s. Here is a pic of it almost finished :

Yes, I tried it and found the same thing - weird, eh?

Well I think we found a bug - imagine that, the Gauntlet R0M can't run properly on a  Gauntlet control panel  :P

It's sound more a emulation/input bug, so someone should submit this to the bugtracker at the mame site.

I doubt deleting all config files works this time, which sometimes works, but did you try a older version which run this game fine?

I tried a few different version ranging from 36 to 97 and the problem persisted with Gauntlet "rev 14".

I just got the 135 set so I'll try that too :)

You won't find mappable/traditional start buttons games such as this.  Earlier versions of MAME inaccurately tried to separate the inputs, I believe.  Most Atari games in the mid-80 to 90's had dual function buttons which worked as both an in-game action button and a start button.  MAME is correct to not allow external buttons to be juryrigged as a start button, it's accurate to the original machine behavior.  If you were to map whatever external button you wanted as "Button 2", I don't see why that would not work.  It wouldn't work as a global solution and would need to be assigned per game and whatever button you assigned would also function as the in-game action, but it would work.

0.135 works fine with Button 2 functioning as both Magic and Player Start for each player.
