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.
