reports have come in about 3rd-party cards not working properly mine is third party and it works so...
Action Replay supports the drag and drop feature just like Windows. Open the Action Replay program and then drag and drop SID5.Installer.zip and SID5.Loader.SplinterCell.NTSC.zip to the memory card. In about half a minute or so it should be done.
before you unplug make sure you "safely remove hardware"
Insert your memory card into your Xbox before you start it up.
Once you?ve started your Xbox, the MS dashboard should appear
Select Memory,Select your card, Select the splinter cell game saves, and copy them to the xbox.
Boot Splinter Cell, select "START GAME", Select "Linux", select Checkpoints (it will be blank).
All menus will be self explanatory
Select Create EEprom Backup.
Select Create MS Backup.
If you want you can Create a C Drive Backup.
If you want to use Xbox Live You must select Install Dual Boot Softmod (must have a XBL account before this is done)
If you aren't going to use XBL Install Single Boot Softmod.
Please be aware that SID 5 will take around 15-30 seconds to install a file called "shadowc.img", so if you see that it looks like if it froze, don't panic, and let it run.
that's it for the mod.
