How to make Eternal Poison (SLUS 21779) playable

In official PCSX2 0.9.7 beta 3113, you click Config then Emulation Settings.

In EE/IOP Panel, choose Full under Clamping Mode.


In VUs Panel, choose Extra under Clamping Mode.


Now the background become normal. In general, you'll encounter black background colour without the special settings I provided.



I suppose you can beat the game eventually from now on.
