Tested and Working: TSOP Flashed Xbox v1.4
This post contains both a Redump ISO version that matches the checksums from here http://redump.org/disc/13652/ and a Folder XBE version that was made from said Redump version and is ready to put on a xbox HDD and just play. If you have to ask what to do with the ISO version please just download the Folder XBE version, I already did all the hard work for you.
