I'll take the terminology debate to another topic.
pino@pino-laptop:~$ file Desktop/X816.exe
Desktop/X816.exe: MS-DOS executable, MZ for MS-DOS
Modern desktop operating systems (64-bit Windows, OS X, and Linux) cannot run MS-DOS executables as native processes. Are you recommending to run x816 inside the DOSBox emulator?
For comparison, a 32-bit Windows executable, which run as a native process under Linux with Wine libraries installed, looks like this:
pino@pino-laptop:~$ file .wine/drive_c/Program\ Files/nocash/no\$sns.exe
.wine/drive_c/Program Files/nocash/no$sns.exe: PE32 executable (GUI) Intel 80386, for MS Windows, UPX compressed
