These are lists that contain many variations of values used by program code. Corrupting using these value lists dramatically increases the chances of hitting game code.
For general purposes, a recommended usage is any Branch lists as Limiter and the NOP list as a Value. Play around with the Branch lists. You can also swap the Limiter and Value lists for different results.
Limitations of the lists
The PCSX2 lists were added in 5.0.4. The Branch lists currently only a limited amount of possible values (-200 to +200 generally).
