    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?

    Haven't gotten a chance to look at it myself, but if you e-mail me a copy I'll take a peek and let you know.

    I'm interested as well. Can you keep us informed on your progress?

    Bah..... I forgot to take a look at this when I was at home, and can't re-read that e-mail here at work. Can you send me the readme file though, same address?

    #5 8 years ago

    Got the e-mail, sent the patched file back to you. But yeah, you need to burn the file onto a new chip..... don't have that ability at the moment, not until next paycheck at mid-month when I was planning on getting a burner anyway.

    Thank you Hans. I have a line on someone to burn it.

    I have spare IJ sound ROMs. Are these the same chips as used in the Corvette game ROM?
    How do you tell?

    Edit: Looks to be all the same chips, as the file sizes are all 512k. Not exactly sure which EPROM's you'll need. Either way, you only need to do the game ROM though, not the sound ROM's
