>If you know your NES library, you might recognize those characters from one of several NES games that came out here (maybe River City Ransom, or Super Dodge Ball, or Nintendo World Cup). Here in the U.S., those games were three completely separate franchises sold by completely different publishers. But in Japan, where they originated, they were all part of the same franchise, revolving around kids attending Nekketsu High School. The star off those games was Kunio-kun (middle-left in the above screenshot).By 1992, Technos had opened its own U.S. office and was set to start self-publishing its Kunio games here under a unifying banner. Kunio-kun of Nekketsu High wasn’t exactly English-friendly, so what we were given instead was “Crash ‘n the Boys” of Southside High. Even the art direction got a Western facelift for an American audience that had not yet embraced Japanese aesthetics.
>In 1992 they announced Crash ‘n the Boys: Street Challenge (a sort of street Olympics game) and Crash ‘n the Boys: Ice Challenge, and even started teasing a third game, Soccer Challenge. Unfortunately for would-be Nekketsu fans in the West, Street Challenge would be Crash’s only outing. In fact, we wouldn’t see another Kunio game here until 2008’s Super Dodgeball Brawlers on the DS – that’s 16 years!
