I got the LED Patch for Williams WPC Game ROMs. It supposedly works on all the WPC games.
From what I can gather it changes a command to double the time it takes for the LED to activate which apparently is just long enough to keep it from inadvertantly lighting.
The directions state to run the patch, select one of 3 options and save the file with a slightly different name.
Please correct me if I am wrong in any of this as the README file was written for programmers of which I am not.
The issue is I cannot figure out how to get the patch to run. It def does not use Windows. Has anyone else used it before? What software did you use?
