Now, you need to actually execute the proper file to start the game .
Typically this will be a .bat or a .exe file .
To find out what it's name is, type
a) "dir *.bat" followed by Enter and look if any filenames are listed .
b) "dir *.bat" followed by Enter and look if any filenames are listed .
c) If there is a file like "run.bat" or "popple.bat" or "start.bat" or something similar, that is likely the file needed to start the game .
d) Otherwise, if there is a file like "run.exe" or "popple.exe" or "start.exe" or something similar, that is likely the file needed to start the game .
e) To start the game you need to execute one of the files found at step c) or d) . To do this, type the name of the aforementioned file (typing its .bat or .exe extension is optional) and press Enter . For example, if you want to execute a file named popple.exe , you would need to type either "popple.exe" OR "popple" and press Enter .
You may want to consider purchasing a DOS primer (like MS-DOS for Dummies) to help you get started with DOS and its commands . Alternatively, maybe somebody else can recommend a good online tutorial . My own introduction to MS-DOS was a read-through of the manual that came bundled with MS-DOS 5.0 , which is another valid option if have one (otherwise you can borrow a virtual copy through archive.org 's lending system) .
