TY the Tasmanian Tiger

The actual aspect ratio change is vert+, but the sides outside of the 16:9 ratio are covered with fake windowbox borders.

To blank the bars out, open "TY.exe" in a hex editor, then search for the bytes:
"C7 45 D8 00 00 00 FF C7 45 DC 00 00 00 FF C7 45 F4 00 00 00 FF C7 45 F8 00 00 00 FF C7 45 D4 00 00 00 00 C7 45 F0 00 00 00 00" and replace it with
"C7 45 D8 00 00 00 00 C7 45 DC 00 00 00 00 C7 45 F4 00 00 00 00 C7 45 F8 00 00 00 00 C7 45 D4 00 00 00 00 C7 45 F0 00 00 00 00".

Optional FOV: When the exe is open in the hex editor, search for the bytes
"F3 0F 5E 0D CC F1 66 00 F3 0F 10 05 D8 4D 63 00" and replace it with
"F3 0F 5E 0D CC F1 66 00 F3 0F 10 05 DC 4D 63 00" ("D8" with "DC"), then search for the string
"61 32 55 30 2A A9 33 3F F3 04 35 3F 5E 83 6C 3F 7B 14 AE 47 E1 7A 74 3F 00 00 80 3F" and enter a little endian floating value after the final bytes "00 00 80 3F" for example:
"61 32 55 30 2A A9 33 3F F3 04 35 3F 5E 83 6C 3F 7B 14 AE 47 E1 7A 74 3F 00 00 80 3F 00 00 40 3F.
