(More info on SFNightmare)
You got .iso or .bin?'
If you don't you need to get a Iso/Bin converter
Then download old or new Daemon tools
(DO NOT USE ANTI-BLAXX, IT FUCKS YOURE SYSTEM)
Ok, Open up SFNightmare.exe
You will now see many buttons to click, However do not click on anyone of theese! However the buttons you shoul'd disable is
Disable CD
and
Disable Node
-- Now when you've done that (Will take some time)
Mount the Iso/Bin in daemon tools,
Install PoP2,
Play the game!
