[Solved] How can I get PSP games' original font?

[Tsukuro]

Someone told me that emulators don't use PSP games' original font since they're copyrighted. But is there anyway to get the game's original font and make PPSSPP use it? (I mean the in-game text, not the system settings text on the blue background for PPSSPP)
PS. Someone may have mentioned this somewhere (and maybe I missed out) but if it's okay, can anyone tell me the details on how to do this? I think that you have to put the font (.pgf) files into the flash0/font folder of the emulator, but where can you get/access the font from the game on the real PSP?
Thank you so much!
