On each version of Evil Twin, you can hack the game to play fullscreen and enjoy a better field of view. If you play on an original Dreamcast, beware of high fps drops.
On Dreamcast you need to edit with an hexa editor the track05.bin if you use a .gdi dump. Otherwise edit the .cdi disk. On Mac you can use the free Hex Fiend and HxD on Windows.
You just need to find & replace the following values.
Don’t forget to configure the video output of your emulator to widescreen.
