EDIT: Updated the tool to MTool_A10U15 (around 1 month of updates from previous release), still waiting for U16.
EDIT2: Updated the tool to MTool_A10U16 (around 3 months of updates from previous release), probably is the last update before the new version, I would anyway try the U17 if I can find it.
How to play:
1) Recover the old tool I've linked before, get the game from

2) Extract the game folder, extract the TrsData.json in the game folder and lastly extract the tool folder
3) Open the tool (DON'T UPDATE IT!), drag and drop the .exe of the game (you will need jap locale to run the game, you can use

direct on the exe once you created the files for the tool the first time, just remember that the tool need to stay open)
4) Enjoy the game in MT english (not everything is translated but quite enough)!
