Tsearch (similar to ArtMoney and the open source Cheat Engine) is a memory scanner/debugger utility developed by Corsica Productions. Tsearch’s primary function is to scan open processes for byte addresses; restricting searches to either "Exact Value", "Range" or "Unknown Values". The searches can be refined by using a "Search Next" (or sieve) option: this re-searches already found results to display results suiting a further refined criterion. From Wikipedia

Remember to always save your game when using Tsearch since in rare occasions it can cause the game to crash if improper bytes are frozen.
