Wouldn't it be cheaper and easier to manage a remastered CD? I have found that the only issue remastering the CD is that when I'm done and have a new burn there is something new to change. For a simple change like this it would make sense to burn it into the CD.

You could eliminate the floppy drive and won't run the risk of having to reboot the system with a custom cheatcode.

Just a thought. Probably not much help.
