I see bootleg, pirate and counterfiet to mean different teams with regards
to media.
In terms of music collecting a bootleg is usually an audience taped
live performance or copies of old demos or otherwise commerically unavailable
material. Pirate is a copied tape or cd. And counterfiet are cds that are copies
of released albums that are made to fool people into thinking they are buying
the real thing (or allow guilty consiences to 'believe' its the real thing) with
full copies of artwork and labels.
For games I would say a prototype would take the place of bootleg. A
pirate copy is of course made at home and a counterfiet is a fake sold by
shady retailers.
Just my opinion of course
