Hi there,

A full list of all release is available at: http://www.vectrexnews.com
(game section)

There is also a rarity list available there.

As for the european releases, they are available / split up into 2 categories. One part of the games has "Made in Rep. of Ire" on the back, and the other part "Made in Hong Kong" , and there is some overlap in these 2 sets (i.e. a bunch games have 2 variations)

There is also a special/rare version of Hyperchase available that has a logo with alternate colors on the cartridge .
