you dont NEED either, but if you want them... ( autorun.inf you could make your own very easily, just a text file
and its only use really is displaying icon in explorer, & what program to launch when you insert dvd )
Autorun.inf ( label will change with every game of course )
Code:
[autorun]
open=Autorun.exe
icon=Setup.ico
label=Ride to Hell Retribution
included in rar file autorun.inf & setup.ico ( taken from setup.exe )
