He probably means system fonts, some games including MH use PSP system font for some things and since those fonts are copyrighted/part of PSP operating system/firmware PPSSPP can only ship free alternative - which looks differently, in many games causing problems due to size differences as can be seen here.

You can dump fonts from your PSP(if you have one), just need CFW to change USB device(in vsh menu) from memstick to flash0, then you can copy font and place it under \assets\flash0 in PPSSPP folder. It's very quick and easy, but doing so you have to remember to never remove the fonts from PSP itself(use copy not cut!) as it will brick it:].

If you're an artist, you could probably create prettier system fonts yourself, unfortunately we really don't have any decent tools to make PSP fonts and those which do exist end up doing some things wrong causing problems in games.:]
