Probably game specific, as content (lower 24 bits) of NOP command is analyzed and compared to predefined values.
Chances that games send GE NOP with example value of 0xA6CEA0 value are rather slim.

Work in conjunction with values set with DRAWN_IMAGE_SCALE. When enabled, emulated VRAM amount is lower.
Resulting VRAM size:
VRAM_MODE 1 and DRAWN_IMAGE_SCALE <= 1  = VRAM size 2MB
VRAM_MODE 0 and DRAWN_IMAGE_SCALE <= 1  = VRAM size 4MB
VRAM_MODE 1 and DRAWN_IMAGE_SCALE 2 or 3 = VRAM size 8MB
VRAM_MODE 0 and DRAWN_IMAGE_SCALE 2 or 3 = VRAM size 16MB
VRAM_MODE 1 and DRAWN_IMAGE_SCALE == 4  = VRAM size 32MB
VRAM_MODE 0 and DRAWN_IMAGE_SCALE == 4  = VRAM size 64MB
Real PSP Have access to 2MB VRAM.
