Hey all. I've got a ROM marked as score 50 - meaning it is hard coded to start dispensing tickets and light the beacon once you get 50 points. I want to change this to some other number, such as 200.
I plan to dump my rom and try to find where that 50 point value is stored. It would likely make my job much easier if I had another rom image with a value other than 50. That would presumably enable me to just look for the differences in the rom images (assuming the rom versions are the same or at least close enough).
Of course, even better would be to find a rom image for "field programmable" high score setting - meaning use of the optional thumb wheel score setting cable. I've already populated the parts on the logic board to enable this but I found there must be a different rom version to enable this to work, as my prototype cable made no difference.
Can anyone provide a rom image for programmable score or a hard coded score other than 50???
Note that this is for a model H (deltronics board), not a model S (skeeball board), so if you have a rom with a label like "SP65" then it won't do me much good.
