GS Memory

Layout

The GS memory is laid out as follows

Address	Content
0x0	Display Buffer 640 x 256 32bpp
0x0A0000	Frame buffer 1280 * 512 * 16bpp
0x1E0000	Frame z-buffer 1280 * 512 PSMZ16
0x320000	Start of texture area, size 0xE0000
0x400000	End of memory

A progressive scan 640 x 512 * 32 would need to be. This works because we have the same amount of data for textures.

0x320000	Start of texture area, size 0xE0000
