Depends on where you live...

i did this and burned it onto my vebatim dvd r dl and put it in my xbox and it said it and no storage on it..

you burned it wrong then.

i just tried i different way i played the game set it up to der reise and swapped the discs and then played and press start and control but there was no option for tactical

You Burn The .DVD file after you replace the files in the ISO.

i followed these steps but i keep getting dirty disc error when i hotswap and i cant figure out what is going on is it a bad dvd or did i mess somthing up? i was just thinking about it when i opened abgx360 i didn't change anything in there was i supposed to put my region code in there even if the waw iso is region free and if so do i have to re download waw iso cause i already modded the iso?

ok so everyone that is having the dirty disc error when they are trying to hot swap i finally figured out a way how to make it all work 1. follow seth's tut thanks for that again seth 2.have to open your xbox 360 to do this 3. put ur original waw game in the drive 4. press y hover over install to hard drive now the key to the trick. do your hotswap put modded version in now click A to start the download you'll get the famouse dirty disc error but no worry press B to take u back to install to hard drive instead dpad up to play game then just click A game will load up have fun with ur modded zombies.  I made this tut because i was one of those people getting the dirty disc error and didn't find a tut anywhere how to fix it so when i found out i posted for people like me. and if someone is gonna say i posted this tut b4 prove it cause i looked all over and found nothing but if u can prove ill give u credit if it helped u please give a thanks.....   HAPPY MODDING
