just come across this website
if like me you in around 38 and was brought up with raleigh supertuff burners / raleigh record spring racers and the atari 2600 then you will remember those hand held lcd game and watch games either single screen or double screen with a platic ribbon connecting the two.
i had the orange donkey kong one twin screen (which can be played on a ds with a r4 card
but on this site you can play replay the games via flash
it even has speak and spell (still cant understand what it says though) lol
well worth a look and a play to bring back the momories of christmas 1982http://www.handheld.remakes.org/online.php
