The "All Borders" crop mode was previously creating an aspect ratio that
was completely incorrect when using modes outside of Auto/4:3. We now
scale the aspect ratio relative to the PAL/NTSC aspect ratio to account
for this, regardless of how much of a border the game configures.
Overscan cropping also produced an incorrect aspect ratio outside of 4:3
mode, resulting in minor horizontal stretching. It is now correct,
however, this results in black borders being added in 16:9 for most
games.
To remove these borders, you have two options:
- Use the "Stretch to Fill" aspect ratio. This will scale the GTE
aspect ratio to fill the screen.
- Use the "Only Overscan Area (Aspect Uncorrected)" crop mode. This
mode retains the "old" behaviour, resulting in a stretched image.
