In Dos, try to type it's in the following way:
sangoku.com and add the following options after the program name:
/h or
/? or
-h or
-? so it looks like this:
sangoku.com /?
Or try the same with
main.exe
Maybe there are options that are able to be set for the game before starting, and that might be what you need to set the EGA mode for the game.
