From a quick look - Core/HLE/sceIo.cpp is hardcoded to return only 1gb free:

ppsspp/Core/HLE/sceIo.cpp

Line 1850 in 3289614

// TODO: Pretend we have a 2GB memory stick? Should we check MemoryStick_FreeSpace?

The TODO of calling "u64 freeSize = MemoryStick_FreeSpace();" instead seems a pretty fair idea (especially as the ReportSmallMemstick flag already exists if it causes problems)

^ Edit that's the line that causes this particular issue (changing to MemoryStick_FreeSpace() fixes it) - but would be worth doing further down at:

ppsspp/Core/HLE/sceIo.cpp

Line 1989 in 3289614

// TODO: Pretend we have a 2GB memory stick? Should we check MemoryStick_FreeSpace?

too

Hm, interesting - we correctly check the free space when games are using the savedata APIs to check for free space, but not in other conditions like this. Maybe we were worried about games not supporting 2GB+ sizes, as we've seen that problem for the savegame check...

I'll fix this right after the 1.18 release, to reduce the risk of breakage. In the meantime, it's probably not really necessary to install data because UMD access is way faster in the emulator than on hardware.

Actually, I'll just bump it up to 1.5 GB now, shouldn't be any risk of overflowing game-internal variables that way. Then I'll fix the reporting properly in 1.19.

[hrydgard]

Although, I still recommend against installing data when running the game in PPSSPP (unless it enabled some specific functionality?). It's really not gonna make anything faster.

The data install size for US version is 928.49 MB while the Europe version is 1003.99
