Can you tell a MAME game to "not" use diagonals?

[equlizer]

There are a few games i play that i "dont" want diagonals.  Is there a way to set it up that way?

[headkaze]

You could try the Mame Joystick Map Editor

Mame has a "not" command that you can try too.

What version of MAME?

[equlizer]

0143 command line

I suggest using Headkaze's app.

Based on the output of this thread, I just tried Headkaze's app. It works a treat.

BTW Headkaze, it's not clear from your site that the app does more than remap analog joysticks. I found it a few weeks ago but kept on searching because all the instructions are for analog joysticks.

[equlizer]

is this a compiler program?  im a little confused

[zorrobandito]

No, it's a standalone app that writes mame compatible joystick settings. The settings in the ini remap some directions to make them more compatible but don't change the physical properties. Basically, it's a hack but it's pretty effective. YEMV.

Example of how to do this in the ctrlr file or game's cfg file:

Code: [Select]

<system name="mspacman">

<input>

<!-- Eliminate diagonal inputs -->
<port type="P1_JOYSTICK_UP">
<newseq type="standard">KEYCODE_UP NOT KEYCODE_LEFT NOT KEYCODE_RIGHT</newseq>
</port>
<port type="P1_JOYSTICK_DOWN">
<newseq type="standard">KEYCODE_DOWN NOT KEYCODE_LEFT NOT KEYCODE_RIGHT</newseq>
</port>
<port type="P1_JOYSTICK_LEFT">
<newseq type="standard">KEYCODE_LEFT NOT KEYCODE_UP NOT KEYCODE_DOWN</newseq>
</port>
<port type="P1_JOYSTICK_RIGHT">
<newseq type="standard">KEYCODE_RIGHT NOT KEYCODE_UP NOT KEYCODE_DOWN</newseq>
</port>

</input>

</system>

You can also do this from the in-game menu (menu >> input - this game).
Example:
Player 1 Up: press Enter > press Up > press left twice > press right twice
There is a timing window for this so you have to enter those commands in relatively quick succession.

Of course, this leaves dead zones in the joystick, if you are using an 8-way.  This is why most people interested in classic games buy a 4-way.  I bought the Galaga/Ms Pacman replacement joystick about 7 years ago and it's still a good low-cost alternative.

Good luck.

I thought mame stopped allowing diagonals in 4way games years ago.  but you can do the nots in mame... (I think selecting the same direction twice is not... so up, not left, not right is up, left, left, right, right...)  But I think the drivers do this now without any changes.

I just find it difficult to play games like Robotron and pacman with a Sanwa JLW and a square gate.  Will a circle help?  I still want to be able to play SSF4 fluently though.

Pacman, I can understand, but Robotron?  You really need the diagonals to be working in Robotron.  If you are getting hung in the corners, a circular restrictor will probably help.

Ordered 2 of those last sat.  Should be here next week sometime   Hope it doesnt interfere with my street figter 4 play
