As title says, which is better ? TempAR or NitePR Revision K??

Ps: where can i find the latest version of both of these ?

Um i know we have nitepr in the prx version under ftb2 prx and tempar ive never heard of that one

NitePR is your best bet. And as you move along into the cheating relm, you can switch off into MkUltra, my personal favorite.

Temp AR uses cheat.db And allows you to hack alot of games not allowed much cheats for the game though.
NitePr uses .txt for files but suports alot larger files up to 80 kb for one game

Actually, TempAR can load a 2 MiB text file in like 4 seconds, which is pretty darn good, but you are kinda at the mercy of Raing, because he maintains the official DB (yes you can manually add codes, but it is a confusing pain in the ass). Technically, you will take up more space on your memory stick with NitePR, because if you had as many codes as are in the official cheat.db in text files it would be like 5MB compared to 2, however, not many people play EVERY game that is in the cheat.db, so NitePR will actually take up much less space.

Also, TempAR uses its own format for codes, which is also more confusing then the normal NitePR fake addressing format, but it is all a matter of personal preference.
