I'm sure there are plenty of people interested in your fix. I'm curious though how you came about this "no need to clear display C" software. Not asking, just curious. From the customers perspective, sans any liabilities on your part, you saved them quite a bundle of money. How much, if you don't mind posting, does your upgrade software run? And, what would the implications be, if any, to you selling to World, or any after market within the industry?
Maybe there just aren't enough of them out there to make it worth your while, I don't know. Being an old U.S. guy, this gets my attention (at least for 15 minutes).
Can anybody verify Vertical Express or World does indeed sell this upgrade?
Thanks
