Ratchet and Clank Going Commando Bug

When I tried using the electrolyser on the first one, the screen darkened and I can't seem to do anything.Edit: Also I tried downloading "Ratchet and Clank: Up Your Arsenal," and Aqatos has some serious graphical bugs. The first part has seasure inducing blue bars and the next section sometimes has graphical layers disappear.

I think those are known issues for the series on PCSX2. That is IF you're using that emulator. Look up in their wiki for solution : http://wiki.pcsx2.net.
If there are any, else wait for their next update.If you're not using that to play. Specify exactly what is used.
