Downtown Nekketsu Monogatari

Downtown Nekketsu Monogatari (River City Ransom in North America, Street Gangs in Europe) was ported to the Sharp X68000, a Japanese computer platform, and released in April 1990.

This version of the game, which was developed by SPS and published by Sharp, features several enhancements to the Famicom original, such as displaying three enemy characters on-screen instead of just two, slightly more colorful graphics, an expanded game world, and new items and special techniques for the player (including some that were only used by certain enemy characters in the Famicom version, such as the headbutt and the whirlwind kick).

The new locations includes several new shops (such as a dojo) and the schools of each enemy gang, each featuring two new bosses. In addition to the player's regular stats, the player also has individual stats for all the special techniques their character has acquired. The more frequently a special move is used to finish off enemies, the stronger that particular move becomes.

Unlike the Famicom version, the X68000 does not feature adjustable difficulty settings. The player can save and load their progress in one of ten save files provided by the game itself.
