I need help sprite ripping.

[JPCSPGamer]

In Namco Museum Battle Collection, I want to rip sprites in the original games, but using 3D scenes, won't work. Can anyone help, please. Any help would be appreciated.

From the wikipedia descriptions, 4 games are brand new "arrangements" remake. Probably sprites can be ripped from those if they have been written natively for the PSP.
The other games are emulated ports of games from 70s and 80s. From those old games, you probably can't extract anything easily, they were just not designed for the PSP. Only screenshots are left?

Well, there is a Image Debugger.
