Evan G screen1.jpg This is a prototype cart for B.O.B. snes_central@yahoo.ca October 19, 2014 1|This cart was on sale on Ebay in June 2013, selling for $152.50. The label gives a date of January 26, 1993, which apparently is 4-5 months before release. The checksum of the game is on the label (7973), and is identical to the final version of the game. There is no reason to believe it isn't identical to final. 14|prototype1/prototype_cart.JPG|Cart| 14|prototype1/prototype_label.JPG|closeup of the label|
