MAMEWorld Forums - EmuChat - when a clone is more than a clone

In the past when Haze would post on his web page, Haze might mention where some specific game version
might be the original source where bootlegs originate from. The recent addition of Pengo is the latest example

Another example why it pays to examine a pcb just in case there is the possibility that it is a version that might
not yet be supported in MAME.
