Apologies for taking so long to close the loop on this topic but.....

I received the ROM from Beaky a few days later, all too easy and stupid cheap. Installation was predicatably easy and hasn't really made that many differences, the only noticable ones being:

- Free Play mode
- Larger font size on the scores, certainly better than the original
- eliminated ghosting on the couple of LEDs that had it
- The wierd one, the ball eject into the lauch/plunger aisle is now really quiet. You can barely hear it when it ejects it at the beginning of a new ball whereas the original ROM really smacked it out there

Overall a good move, thanks for your help on that one Beaky

cheers
