I always use raincoat to flash TSOPs and have three copies of Splinter cell for that purpose (in case one gets scratched). The only exception is v1.6 xboxes of course. I used an old splintercell gamesave I found on xbins, but it required you to telnet in. I did automate it, but is was extremely unfriendly, so I've made it a bit nicer.
The way I use the gamesave is as follows:
-if I am softmodding, get the kernel via msdash
-boot up stock xbox, copy the gamesave files to hdd (via memcard) and load the save via splintercell.
-for a softmod,
--- use the evox screen (ftp) to copy kingroach ndure installer created files to C/E (wipe C first). -DONE
-at this point you could FTP a bios (evox FTP) to the gamesave folder. For example, the splintercell gamesave is in: E/UData/21585554/000000000000/Bios/bios.bin
-Proper case is important! (bios.bin is all lowercase.)
-Select Raincoat form the Evox menu.
-Once linux has booted, press A on the controller to continue.
-wait for success message and reboot.
Do as you see fit with this and the information - if you don't like it, cool, it is for me, but I thought it was nice enough to share.
Other info:
-I altered the Evox menu to remove unneeded items.
-I removed some stuff from the linux package to make more room (512 bios should fit on a 8meg card I think)
-I automated the flashing with a script with minor error handling.
The script copies raincoat, raincoat.conf and the bios.bin to /tmp (ramdisk) before flashing. This should
potentially avoid or at least reduce the risk of hard drive errors, since everything is in RAM before flashing.
To use this on another gamesave exploit, I would expect it to work by only copying the RAMDISK file.
Gamesave exploit for splintercell is here
splintercellexp0.1.zip (no bios included, place your bios it in the Bios folder, call it bios.bin).
If not using Msdash to copy from a memcard: 21585554 goes in Udata, 5553000c in Tdata
Unsure, but you may also have to have Udata named on your harddrive as shown (case sensitive).
Enjoy! Hopefully you can use this to TSOP directly rather than softmodding first.
