"selectable same character" is unique. Normally, this game doesn't allow you to select the same character. This code breaks that rule.

Code: Select all

<cheat desc="infinite time">

This game has the timer (2 bytes. not decrease but increase). Boss character who has the machine gun appears soon (and kills you) when you set "time over now" code.
