You're lucky those last four hucards were loose or some a$$hole collector would have bid a fortune.
From a gaming perspective, you gave up a few great SNES games, but acquired a shitload of the most fun and enjoyable Turbochips. Zonk, New Adventure Island, Shockman, Neutopia, Blazing Lazers, Aeroblasters, Legendary Axe, Galaga, both Crushes, Military Maddness, Ninja Spirit, Bloody Wolf, Splatterhouse, Dragon's Curse, both Bonks...damn. You're set. If anything, you may have spoiled yourself the fun of being forced to play and appreciate sleepers like JJ and Jeff, Power Golf, and Boxyboy.
And no, a sale and unrelated purchase does not qualify as a trade.
