A prototype of Super Mario World 2: Yoshi's Island (under the name Super Mario Bros 5: Yoshi's Island), dated December 19th, 1994, approximately six months before the final build.

While this prototype ostensibly has the same build date as the ys_rom_0_D build, there are code differences that indicate a slightly later compile.
