There were several clones and conversion kits of EBD copied in the 1980s other than "Pinball Pool" (Bell, Italy).
I own one of these backglasses.
"Cowboy Eight Ball" and "Cowboy Eight Ball 2" (LTD, Brazil)
Here is a recent video:
This actually has BETTER sounds.
Main tune is kinda catchy.
"Sure Shot" (Taito, Brazil) which was Cowboy Pool with a different backglass, player scoring numeric segments, and sounds.
There were two others as well, but I cannot remember off of my head.
Basically, copyright infringement was nearly impossible to enforce at that time in foreign countries, and Bally did not really care as these machines were almost always sold as conversion kits, low production, and were never competitors in the market anyway.
Both machines above were part of the forefather time of more modern Taito gaming in arcades most people recognize in the mid 1980s.
These two companies were actually "one in the same" but independent for marketing reasons.
The original Eight Ball had 4 clones from foreign manufacturers as well, some of the kits looked like a$$.
