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.

This setting actually has hidden bitfield too (Big Endian). There are 2 separate usleep values that can be set by this config.
First is set when bit 15 is active. By default, value here is 0x320
