Title: MAME status of Keyboard LED Recoil
Post by: rdagger on January 15, 2006, 12:42:06 pm
I know back in 2002 Dave Widel made a MAME hack for Terminator 2 to allow the gun recoil to be activated by the keyboard LED's.  I downloaded the hack from 1UP's site (http://1uparcade.robandmitsue.com/arcade-downloads.html). 

Has MAME released any official versions that handle gun recoil?
If not, are they planning on incorporating recoil?
And are there currently hacks for other recoil gun games besides Terminator 2?

That wouldn't be something mame would add.

If someone could make an interface that would be generic they might start considering it... but it really would help bootleggers more then it would help us...

But all in all... very very hard to do in a mannor that would work for all / most games.  (basic forced feedback really)

So get a good frontend that can launch different versions of mame transparently and be done with it :)

I just built a prototype circuit yesterday.   It still needs some work, but it looks promissing.

I looked at the code for the Widel hack and it doesn't appear that difficult:
static WRITE16_HANDLER( term2_gun1_w )
{
   wms_scratch_ram[0x000a073]=data;
   if (((data & 0xFF) == 0xEF) & ((wms_scratch_ram[0x000a231] & 0xff00) == 0x0100) )
      {
          set_led_status(0, 1);
      }
      else
      {
      set_led_status(0, 0);
      };   
}

Keep us posted...I'd be interested in what you come up with & I'm sure others here would too.
