Will someone please test this for me? Tron problem.

[unclet]

I am using Mame32 V.81 on WinXP on my 4-player control panel.  My player1 joystick is set to the defaults which Mame32 uses.   My player2 joystick (which is a HappControls Top Fire button Super Joystick) is the one I want to use for Tron so I went into the "Input this game" settings and set the joystick and button mappings for Tron to use this joystick .... no problem.  

The problem is that when I put credits in and Tron starts up then everything works until I move the joystick in the "LEFT" direction.  If I move the joystick in the left direction Tron hangs, I hear repeatable clicks in the game and then Tron restarts by itself.  The game does not hang as long as I do not move LEFT .... which makes the game quite challenging but is still unacceptable  

Of course you would think that my Top fire joystick simply has a bad LEFT microswitch, however, I confirmed that I could remap other games to use this joystick (ie: PacMan and Donkey Kong, etc..)  with no problems.   I can even go into the LEFT direction with no problems.

I was experiencing this Tron problem in Mame32 V.74 so this is why I updated to V.81 but the problem still exists.  

I was hoping someone could help me figure this one out.   Will someone please remap their Tron game configuration to use a non-default key mapping (ie: just remap another joystick to it) and see if you can start the game and move in all directions (especially LEFT) and see if the game hangs?  If you use the default key mappings for Tron then you might be able to play without problem, so I am wondering if Tron hangs due to joystick remapping somehow.....

PS:  My TopFire joystick did work for Tron in MameV74 via Win2000.

Thanks

I am at work so can't do that myself but I don't have problems in MAME with Tron at all.  But be careful you don't have the default "tilt" key set to the same thing as you have the "left joystick" key set to.  That's what it seems like is happening when you are pushing left.

That was it ..... the Left joystick movement was mapped to the Tilt key.     Thanks a lot for finding this for me!

PS: Why does Tron utilize a Tilt key?

Well I don't think the machine itself had a button you'd push to engage the tilt (although I don't know from experience, I'm just speculating).  I DO think that the machine had a tilt sensor that when tripped, would reset the machine.  Since you probably don't have a tilt sensor in your panel, or on your keyboard, the MAME designers, true to the original programming, made sure there was a key you could press to activate the tilt, thus emulating the original hardware as accurately as possible.
