After Super Mario 64 was finally decompiled back into its source code, it was discovered that Nintendo failed to use the O2 compression method when they compiled the game originally. This knowledge has existed for months, but now there’s a way for anyone to get the benefits of an O2 compressed Super Mario 64 with a simple patch rather than command line kung-fu in unix. This patch almost completely erases the lag in Super Mario 64, including the lag caused by the infamous Bowser sub, which now runs at nearly full speed even when the entire sub is in view.
