16 bit color depth bug with NVIDIA card

[Hykem]

test 7th Dragon 2020-Ⅱ[NPJH50716]
jpcsp nvida GPU

jpcsp ATI/AMD GPU

real PSP


yet some psp game use 32 bit color depth, (Gundam vs Gundam Next PLUS)
some PSP game use 16 bit color depth, (7th Dragon 2020-Ⅱ)
other PSP game allow choose 16 bit color depth or 32 bit color depth (Kingdom Hearts Birth by Sleep Final Mix )
The bug is jpcsp + nvida GPU will always use 16 bit color depth, jpcsp + ATI/AMD GPU will always use 32 bit color depth.

PPSSPP Force use 32 bit color depth by default, if you want PPSSPP use 16 bit color depth, you must edit ppsspp.ini "TrueColor = True" ot "TrueColor = False"

I thing 32 bit color is better than 16 bit color,
so I suggest jpcsp also add a option to force use 16 or 32 bit color.

Hmmm, interesting. Thank you for testing this on both GPUs.
I think this will be taken into consideration with the new External GE, but in the current implementation it appears to be a conflict between JPCSP's interpretation and NVIDIA's true color settings.
