Some instructions in the 040 chip are not present in the 060 chip. Therefore the 060 has to emulate them either internally or via a library. Not sure how it works, but it is much slower. During actual runtime, CyberPatcher patches the instructions of the software you are using to use real 060 instructions rather than emulated ones. Thus, it speeds up execution.
I tried CyberPatch on my CS MKIII 060 and it made my system very unstable.
I have since started using Oxyron Patcher (which basically does the same thing as CyberPatcher), and it appears to work very well (and stable, too)!
