Ok I started out just collecting different games but as my collection grew I started holding on to the different label variations. Atari picture/text.....Atari/Sears...Froggo...Zellers...Beagle Bros.(just kidding ). Then I found I'm holding onto carts with different copywrights i.e. Pole Position 1982, 1983, 1988. Looking thru my carts to compile a trade list I noticed M-Network carts have a label variation with the country. I've seen U.S.A., Korea, Philipenes and Singapore. Not that these carts are rare or anything, I just can't seem to part with them. I think I may need therapy.
