Okay, so I've got a nice ball rolling for a PSP game at the moment.
Everything's going very smooth and with very few complications along the road, and besides dialogue text and some remaining chunks of descriptive text, everything's more or less getting close to finished.


Now, there is however one problem I can't seem to solve with my currently limited knowledge.

When PSP games access the memory stick (or basically anything related to the system/XMB itself, like the web-browser, on-screen keyboard screens and save/load features), the strings it uses for this feature seems to be taken from system firmware/bios itself. (Instead of storing them internaly in the game's DB somewhere)

However, some (if not most) games seems to ignore the PSP system language settings and call the strings for the game's native language instead.

Anyone happen to have any idea about how I can change the language settings for these features ?

Yeah, that was what I was hoping for.

So far, I've tried fiddling around and tinkering with two files I thought it would possibly be in.
(UMD_DATA.BIN and PARAM.SFO, both of which contains system information about the UMD media. Stuff such as region code, disc/game ID, name, etc...)
But with no positive outcome.

Guess it basically makes me have to look for it somewhere in the game's exe, hopefully, it's something standard, so once it's been found in one game, it should be quickly doable in all/most other games too.
