SomaTrans was custom made for SomaBringer. Because file formats change from game to game, new custom tools have to be made for each one.
You won't find custom tools for specific games floating around on the Internet, unless it is a Pokemon game. You have two options to get tools. One is to learn how to program and create these tools on your own. Another option is to become friends with a programmer and convince them to make you the tools. The second option is not as easy as it sounds. The first option requires time and patience.
