[HELP] Extract / Rip Images files from PSP Game?

may be error of font , install japanese font for your computer

As far as the PSP community goes, there is not a "true" way to extract cg from a psp game.

I have heard that Gimconv could possibly be used as a tool to use for extract/packing psp cg. But it hasn't been updated in almost 7 years.

As consolation though, you can install the "capture.prx" plugin for your CFW. The plugin takes snapshots of whatever is displayed on the screen. Last I heard the plugin saves in .bmp and .png.

That's what I know.
