I have been looking at some of the tables. And I notice some similarities in the file names. Looking at the installation guide, I got:
classic - play exactly like the original machine but do not use the original artwork for the machine
DX - uses the artwork from the original machine and will often be in the same aspect ratio as your PC screen
WDX - uses the artwork from the original machine, but maintains the original aspect ratio of the machine
PDX - uses artwork from a different machine usually because no artwork was available for the machine in question
What about ?
Club
ACE
AWP
BARCREST
ASWP
BWB
I am sure there are more, that I can't think of right now. Thought it might be helpful to have them all in one place, but I couldn't find i t anywhere.
Thanks!
