You missed the Polish patch, which updates the localization with some new textures and more synchronized voice acting. It should also be noted that it can't be installed after installing the 1.3 patch, not sure about 1.3.1 though.
Any chance we could get a 3840x1600 version?
EDIT: I used the 3440x1440 patcher in this fix to patch the CrazyTaxi.exe and then used HxD Hex Editor to find and replace both instances of 8E E3 18 40 with 9A 99 19 40 to make it 3840x1600.
Common Name Decimal Formatted Value
21:9 (3440x1440) ~2.38 8E E3 18 40
21:9 (3840x1600) 2.4 9A 99 19 40

It seems the "Disable Black Bars" option (in the 21:9 file at least) also removes the black outline on Miriam along with the black bars at the side. Is this a tradeoff?
