Yes its possable to COPY the CD's as there wasnt realy any copy protection on the disks in those days.
However as for downloading any iso's (games) on the net , in my experiance its very hard to find any and besides its illegal and there for i or any 1 elso on here cant tell you where to get any.
The only thing i can suggest is going to
WWW.google.com This is usualy the best place for any sort of games download and try something like cd32 iso or amiga cd32iso or roms................. :blah
