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.
