Disgaea games are incredibly laggy

[TkSilver]

If your trying to play Disgaea without frameskip then it probably is laggy and choppy but if you tell me your settings I might be able to help a bit, I run Disgaea 2 with frameskip set to 1 and the auto box checked and my audio is fine.

Side note I find it interesting you pointed out 3 games that were specifically built for the PSP to compare to games which were ports from the PS2 and possibly not as well optimized, but that really doesn't matter.
