Would 'ya look at this! A programmer in Japan Germany made a Vectrex port of Bomb Jack! I'm hugely impressed that a game this colorful seems to work as well as it does on this monochrome system, but I imagine that any British people who see this will slingshot their underpants across the room with an erection stiffer than their upper lips. "Jolly good show! Now do Silkworm!"
EDIT: Apparently the developer was Thomas Sontowski, from Germany. The Germans sure do love them some Vectrex! Kristof Tufts did some pretty amazing stuff on the system as well, making Vex ports of Galaxian, Time Pilot, and Moon Patrol.
