2600 support is something Hyperkin could have easily done, but probably didn't happen solely due to the market percentage who would be interested in it whatsoever. The Atari was a phenomenon of North America almost exclusively; most Europeans don't really have a ton of fond memories, nor do Asians. Hyperkin likely feels that given the small number of users who would want that coupled with the sheer age of those carts, it just wasn't worth it.
