NBA Jam XXX (SNES) | Casual Play
This is a previously unreleased, in-house-only version of NBA Jam (dubbed NBA Jam XXX) for the SNES allegedly featuring vulgar commentary by the game's original announcer, Tim Kitzrow. The circuit board was sent to NintendoPlayer.com by an anonymous source, with permission to do whatever they wanted with it. NP dumped the ROM and released it to the public on August 5th, 2012. Audio changes aside, it seems to be identical to the retail version.
