It looks pretty decent. I'm surprised at the efforts they went through to reproduce a Lynx cart. They apparently did the same thing for their Genesis carts as well.
Hopped over to AtariAge to see if it was in their directory (it's not), but there is an
official thread there discussing the game and the release. According to Clean Larry, this game took six years to produce.
