There is no such thing as an "RPG games' translating tool." What you are looking for, I suppose, is AGTH, the anime-game text hooker. Use the search tool or Google to find it.
What you are looking for is AGTH + ATLAS and Translation Aggregator. Find a thread on a forum that has an introduction and F.A.Q. Good luck!

Chiitrans uses AGTH to hook. Both Chiitrans and TA are good. You can't go wrong using either, and you should try both to see which one you like better.

i use ITH, (you can just pick your game from a list of processes instead of having to fuck around with the target line) but it has trouble with wolf games
