The majority of Monaco Atari 2600 games look like this:http://homepages.ihug.co.nz/~pinwhiz/nz2600.htm
Monaco imported the Game boards and printed the boxes, labels and (some) manuals here in New Zealand.
This "assembly" meant they were able to put "Made in New Zealand" on them and avoid import restrictions/duty etc.
Loose cartridges are easily recognisable by the rounded corners on the Labels. All are PAL format.
Boxes have Monaco's name on the rear, manuals are a mix of imports/locally printed.
Sometimes they are over-stickered with the Monaco name and details.
