[RM2k3] Protecting Games?

I didn't know where else to post this so I figured since it's a request of sorts it might fit in here.

I downloaded an RPG Maker 2003 game called Starless Umbra that had protected it's resources by including them all in a single EXE file.  I was wondering how they pulled this off if anyone knows.

I would contact the author but I couldn't seem to find a way to contact him.

Go to Project -> Create Gamedisk

That will do it. Include all the resources you use, so import them from the RTP if you are using RTP resources. Otherwise, people will need the RTP to run your game.

I tried that just now and all it did was put all the files in an LZH file and created an installer file which extracted them all anyway back to the state it was in before I created a game disk.  Perhaps I had to do something in the installer itself that I missed?  There were two check mark boxes but all they said was ? ? ? ? ? ? ? ? (without the spaces) which I'm guessing is supposed to be Japanese or whatever from previous experience with programs that use foreign languages that the extra language support of Windows doesn't work for.

I found out the author of the game used Molebox to pack everything into a single EXE file.
