Boggy '83 (Kaneko, 83)   
Info from Randy Hoffman:
The situation with "Boggy '83/'84" is now much clearer.
"Boggy '83" was the original version, developed for Taito by Kaneko.
"Boggy '84" is a bootleg of this by "Eddie S Games"
(that's what appears on the title screen), but the board is clearly original Kaneko.
I speculate that when the original game didn't sell well, Kaneko got stuck
with a bunch of the boards, and some enterprising person or persons decided to, um,
"creatively dispose" of them.
