10 years ago, there was indeed a p192c Experimental Edition, which would likely not work anymore and I don't think anything it contained is still in the current pakset version.
The current status is: Main Devs of p192c don't work on an Extended Edition because there is still much to do in Standard. Citarofahrer claimed he'd do it, but hasn't shown results. Main problem seems to be that Extended can't read shorthand dats, so you can't get a playable version - you'd have to write new dats or write a program to extend the dat files.
I'm certain a playable extended version - even without extended-specific-features - would be a treat to many, and might be enough to spark an actual development branch. After all, for conversion you don't actually need graphics, you just need to be tech-savvy.
