A few months ago I found this odd looking Lagoon cart among a bunch of other beat up SNES games and picked it up for $6. I opened it up and unfortunately it's just a regular retail PCB, that looked rather worn as well, like it had been sitting out in the open.
The cart casing has me wondering, though. I've never seen one like it before, whether it be unlicensed game, boot, cleaning kit shell, or other. It has a 4-screw design and lacks the grooves and other features of a typical SFC cart. The notches on the back look like they were drilled by hand with a dremel tool afterwards to use the cart in a US system.
Anyway, I thought it was worth sharing, and maybe someone has info on it?
