I played Wizardry Gold on a PC running Windows 95 with a Pentium 100 mhz processor (I think it was a Pentium 100...it was in 1995 or 1996 anyway)...worked fine [img]smile.gif[/img]
I never saw Wiz 7 not titled Gold or not on a CD lol so I don't know what trouble it would entail.
I played the originals through the Ultimate Collection on this very system early last year...they worked fine too.
