If you can successfully hotswap and don't have any of the gamesave-hack games, then I'd suggest the audio exploit.
Here's what you need:
-
Swapless audio exploit ST.DB
- xbedump.exe
- Evolution-X (evoxdash.xbe and evox.ini at the very least)
1. If you have ripped audio, rename E:\TDATA\fffe0000\music\ST.DB to ST.ORG
2. Copy the audio hack ST.DB file to E:\TDATA\fffe0000\music\ST.DB
3. Use xbedump.exe to sign the EvoX dash: xbedump evoxdash.xbe -audio
4. Rename out.xbe to "exploit" (no extension)
5. Place exploit and evox.ini in E:\ (root directory). The other EvoX file are optional (skins and trainers).
6. Place your BIOS file(s) in the E:\Bios directory. These MUST NOT be BFM (bootable from media)!
7. Boot the Xbox and run the swapless audio hack (Music, [blank], Copy, Copy, New Soundtrack, Done). It should go into EvoX.
8. Flash the chip.
9. After successful flashing, and if you had ripped audio, delete ST.DB and rename ST.ORG back to ST.DB.
You may also have to prepare evox.ini by putting in the right codes for your particular TSOP, and to enable the flash command (make sure it's not commented out).
Also remember that you can't flash a Winbond TSOP with EvoX. If you have one, use raincoat instead.
