DG's TX2 is an unpacked look at the binaries in Dmitry Grinberg's TX2 ROM. LifeDrive is the same thing, except for a stock LifeDrive. Treo 650 is weird. treo 755p is the same, just with 755p bits. ROM_Archive.zip is an archive of many devices. - Media in this zip is the files required for installing Media 1.0 on a device which did not have it initially. (like the T3, which had Photos instead) - T_ to T5 Update is a really cool ROM nick where you can upgrade a T|T, T2, T3 to have a software featureset more like the T5. Recommend doing to some degree - read included documentation. McFile is another file manager. The rest are the same. ROMS.WinAce.compressed.ace is an archive I recieved long ago for ROM nicking purposes. TX2.ROM.zip is the packages for the TX2 custom ROM.
