EDIT :: Improvement! Validating file existence now requires ONE section. One more thing to my RGSS knowledge! [^.^]

OK, this is my first ever script, so don't expect it to be of SephirothSpawn's quality, or that great at all for that matter, but still, here it is... File check protection:

This is for retail games, so say, the creator can make a text file called 'rubberducky', and the game will only work if 'rubberducky.txt' is present. Thus you can keep tabs on who gave illegal copies, since the file has their name in it!

Instructions

Add this above EVERYTHING!

NEXT

Replace:

FILENAME.EXT - with - Whatever filename and extension you wish (I reccomend text)

AND

ERROR MESSAGE - with - A custom error message!

Limitations

- File can be hidden, defeating the purpose of this exercise.
- Array has not been checked but SHOULD work!
- SDK has not been checked... Not sure if it works.

Future Plans

- Hide voids the file!
- Serial database input! (I doubt this one though, but I will try!

I don't expect you to give credit, but don't claim it as yours either... If you do, my ducky shall claim your soul...
