Really? I know the first game did, but I'm not sure of the other two routes, I know these was a fansite that has all the dialogue translated on a page with pictures.
As for Langrisser 5, I actually beat it, and the game was sluggish as hell, sometimes the computer would spend nearly a min trying to move one unit. It drives me insane, what even pisses me off is that they implement that terrible moving system to the PSX version of Langrisser 4. Also, the plot is cringy stupid near the end.
