Resolution

Here is an example of a (probably) unusual PSX resolution, 720×576 (PAL interlace). This is accomplished by setting the PSX to display a 720×576 image and then constantly updating the upper part of the image using DMA as the PSX has a hardcoded framebuffer of 1024×512 pixels. Luckily the RAMDAC wraps when reaching the bottom of the image, making it possible to show more than 512 lines. The image is scaled to 768×576 to have the right proportions on a computer monitor.

This is a picture of “Penny” (Kaley Cuoco). This will probably not work in any current emulator.
