This page covers global game speed patches.
Each of the Bio Menace games has two internal rate values, which basically determine the speed of (almost) everything. As for the two rate values: One is used while music is turned on, and the other while it's turned off (permanently, as toggled in the menus). For consistency, the former value should be exactly four times the latter. The higher the values are, the faster are the games running globally. Some would recognize the former value to be the so-called "OPL rate", commonly associated with IMF music tracks.
A word of warning: These patches affect anything when it comes to speed, even in-game counters. To correct such counters, ones can check out the Patch:Bio_Menace/Practice_mode and Patch:Bio_Menace/"How_to_Pay_for_BioMenace"_section pages.
