¿How to add a dummy file to a selfboot game?
 

somebody have tried it?

the self boot games are all pre dummied, that's why when you dload a game like sega tetris, that is only 2 rar files it expands to be over 600mb when you unrar it...

Yes i know it, but i have some pirate games that have selfboot without a dummy file.
Some of them have 300MB of freespace.
