it does work, here's the basics of how the code works:

cupcade setup:
{ 2, KEY_LEFT }, // Joystick (4 pins) [line-0]
{ 3, KEY_RIGHT },// [line-1]
{ 4, KEY_DOWN },// [line-2]
{ 17, KEY_UP },// [line-3]
{ 27, KEY_Z }, // A/Fire/jump/primary[line-4]
{ 22, KEY_X }, // B/Bomb/secondary [line-5]
{ 23, KEY_R }, // Credit [line-6]
{ 18, KEY_Q }, // Start 1P [line-7]
{ -1, -1 } }, // END OF LIST, DO NOT CHANGE


regular setup:
{ 25, KEY_LEFT }, // Joystick (4 pins) [line-0]
{ 9, KEY_RIGHT },// [line-1]
{ 10, KEY_UP }, // [line-2]
{ 17, KEY_DOWN }, // [line-3]
{ 23, KEY_LEFTCTRL }, // A/Fire/jump/pri [line-4]
{ 7, KEY_LEFTALT }, // B/Bomb/secondar [line-5]
{ -1, -1 } }; // END OF LIST, DO NOT CHANGE


notice my line number additions. They point out the entry number that you need, in order to set the vulcan nerve pinch

now, you need to find this line:
const unsigned long vulcanMask = (1L << 6) | (1L << 7)<br />

change the numbers 6 and 7 to whatever combo you need. If you were to use the above regular setup, you could change the vulcanMask to (1L << 4) | (1L << 5), which would set the vulcanNeverPinch combo to your 'A' + 'B' buttons (leftctrl + leftalt). so it's basically just counting the number of entries (starting with '0').<br />

You can also use my version of retrogame, which allows for the vulcanpinch + up to 6 combos. it's set up the same way, you just enter in the two numbers that correspond to what combination of entries that you want to use.

Thank you for the quick response. The "If..Then..Endif" in the file was throwing me off for some reason, and I wasn't starting at 0 when I counted.

The "pinch" only seems to work within the menu. When I launch Mame4All and start a rom it doesn't seem to work. I have to press ESC on the keyboard to get back to the menu, but then I can "pinch" to exit the menu.

My first combination was the buttons for Player 1 & Player 2. I mapped an "Enter" key to be used when navigating the menu. My second combination was Enter and Alt-Fire. Both only worked within the menu, not the game. Am I doing something wrong?

I think I am going to make the switch to your version, I don't know if this will resolve the issue, but up to 6 combinations will be handy.

Thank you for all of your help. I am now at 95% completing my arcade cabinet, and the excitement is building.

Sounds good. I will give it a try.
