An old emulator for the Super Nintendo Entertainment System (aka Super Famicom). It used to be good, but is no longer supported. You're much better off using the frequently updated and incredibly optimized ZSNES; it sets the new standard.

A Shackteau is a humble, weather-beaten, structurally questionable shelter located in a spectacular or highly coveted place—Wales, Jackson Hole, Sun Valley, Crested Butte, coastal Maine, the Alps—where the building itself may be worth almost nothing, but the dirt, view, access, and mythology make it absurdly valuable.
In use:
