Add 480x272 sampling/optimized mode for the PSP. #51

Closed eatnumber1 closed 4 years ago

eatnumber1 commented 4 years ago

This commit adds both a 480p input sampling mode and line2x optimized mode for the PSP's 480x272 picture. The line2x optimized mode is enabled automatically when the sampling mode is selected.

When in-game, the PSP outputs a letterboxed 480p picture. The active portion of the screen is 480x272, but is treated as 480p (480x720).

In addition, a line2x optimized mode is added which produces a 960x544 output picture, which if desired the top + bottom pixels can be dropped producing a 960x540 (qHD) picture.

To generate a qHD picture, use the following settings:

V. Active: 270 V. Backporch: 135
