It's been radio silence for some time now. The improved 1.0 version requires a new build of pinmame, a copy of Pinsound Studio, the sound files and a couple of other bits and pieces.
The Pinsound folks understandably don't want to have their software running on a commercial product without some kind of recompense and proposed that DP let them have the sound assets from BOP 2.0 (so they can make a remix for 1.0 using 2.0 sounds). DP weren't interested in that and to be honest are not really interested in the 1.0 upgrade at all as they have bigger fish to fry with TBL etc.
So that's where things have remained. I'm likely to sell my BOP at some point soon as it's not being played, but there is one more person with a copy of the update; he did a lot of beta testing and lots of tweaks to the sound files. He's willing to host the update on his website along with the install instructions (it's not automated, you need to hook a keyboard and mouse up to the PC in the machine) but only once DP / Pinsound are happy. He has posted in this thread before but I'll let him decide if he wants to make himself known or not.
Yup, all good thanks, caught it in time so no lasting effects
