FE5 shows the Shaya patch, which is all good conversations, garbled menus (as I've heard; I haven't actually tried an FE5 translation in quite some time, and don't want to bother with a half done translation).
FE4 seems to list an older translation than Project Naga, which might work, but I might as well get Retroarch installed anyway, even if my initial reason is for FE4.
