I'm still here too. Just *very* busy at present. :(

I'm sorry, I still haven't looked at the recent changes, I hope I will in the
next few days.

I tend to agree with Arbee, however. No matter the amount of code duplication
we must deal with. The proper way to build a package is to build it from the
upstream source IMO.

I've lately discovered that png files in artwork/ should be distributed as mask
images for the -effect switch, I'll commit the modified mame.install file ASAP.

Cheers!
Cesare.
