The EQEmu supported clients are mentioned here:

http://www.eqemulator.net/wiki/wikka.ph ... ntFeaturesKeep in mind that THF does not have the SoD HP/Mana/End formulas enabled (as far as I am aware), so you don't get the extra benefit from them and your HP/Mana/End bars will never go to full due to that. Also, keep in mind that THF runs some heavily modified source, which makes it hard for them to stay current with EQEmu (as it has to be done manually which is a major pain I am sure), and so it is not likely they will support the RoF client anytime soon. The EQEmu Devs are still working on a solution for the new RoF client anyway, as Steam has been doing updates to the download which breaks the compatibility. The solution will probably require at least semi-regular updates to include new client versions as they get added, which is something else that may make it hard on THF to keep up. Though, maybe the move from SVN to Git will make it possible for them to do merges, but that may depend on how different the source is (which I believe is considerable).
Either way, that Amazon download is definitely not a supported client on any EQEmu server. Your best option may be to stick with Titanium, though you might want to try out SoD or UF and see which you prefer. Unfortunately, there is no legal way of attaining SoD or UF clients anymore, so you would need to find the EQEmu compatible version(s) of those on your own if you want them. You can still find the SoF discs here and there, but that client has some stability issues which are not present in the newer clients.
