MEMSIZE flag not respected in homebrew(?)

[LunaMoo]

Tried to check that Quake II port homebrew for other issues, and it's currently crashing due to lack of memory despite having MEMSIZE flag set to 1, as can be seen:

In case the location matters, it's PARAM.SFO is packed inside memstick\PSP\GAME\QuakeII\EBOOT.PBP.
Extracted PARAM.SFO looks ok I guess -

When it comes to MEMSIZE, it certainly does work fine with commercial games, that is while using ISO, not sure why it fails with homebrew.:]

Is it not reaching here?

ppsspp/Core/PSPLoaders.cpp

Line 151 in 2c6161c

UseLargeMem(paramSFO.GetValueInt("MEMSIZE"));

Maybe it has to do with the PSP_PBP_DIRECTORY stuff.

It wasn't reaching to neither of the two MEMSIZE checks there, and yeah it goes through PSP_PBP_DIRECTORY then to Load_PSP_ELF_PBP which doesn't have MEMSIZE check.

Adding InitMemoryForGamePBP(loadedFile); to case IdentifiedFileType::PSP_PBP_DIRECTORY: fixes it, so I guess I'll open PR with that.
