As far as I know, nobody has cabbed it up yet because it's such a minor tweak. It's very easy to do with a registry editor like PMH. It is included in the DiamondTweak program (along with the edit to enable Burst Mode) , if you don't want to fool around with the registry yourself. Remember, not everything in the DiamondTweak program works on the TP.
Registry edit to enable sport mode: HKEY_LOCAL_MACHINE\SOFTWARE\HTC\Camera\P8 -> change the value “enabled” from 0 to 1
This will allow you to take 5 pictures in succession.
