I use my phone to translate J>E E>J and i always just use Romaji since there is no real need to use the in-game translate for everything, i also don't know what the difference is between it and actual Japanese characters since i don't speak it, but its never failed to get an answer from people so i don't see why you need Windower for something available from the internet with the games Windowed mode.

Aaaaaaaaaaaand windower is marketed just like steroids, they call it a "Enhancement" and not a edge which i think is just total BS since its clearly an edge over anyone not using it.

One click of a button and you can change every single equip for a spell/ws/day/weather you name it while if you play by the rules you only have 5 lines for commands....

Don't be lazy and play by the rules.
