Hey there
Is this game compatible with DosBox? It should say so on the review. This is another way of playing as DosBox emulated old sound drives so you won't have to worry about the BootDisk.
Take a look at this:

As for the executable... yeah it could either be a .EXE or .COM sometimes .BAT but that usually just calls a .EXE or .COM file. Someone who has previously played it should post you the file name.
