Hello, finally, I got around to finishing the untranslated pigman route. It is buggy and very clearly unfinished. But since unlocking full gallery won't unlock these scenes, you have to play it if you want to see what it has. (I am adding another save with a full gallery bar pigmen, as I thought I could just unlock and get everything without playing the buggy mess, but that was not the case)
If you want to play thru the route yourselves, I can't recommend it. But some advice for the brave ones.
Do not scroll thru dialog, it tends to get stuck if you won't let it finish, meaning you will have to quit and load.
In the pigmen camp there is a curtain in the upper wall, do NOT go there once you progress from camp to the village, the area is routed back to camp. (In RPG maker, you have to set where doors lead. In this case, it leads from camp 1. to the room 2., so simply 1->2 and back 2->1. But in the village map, its the same curtain, meaning you go from village 3. to room 2., 3->2, but then 2->1, back in the past, to a camp map where you aren't supposed to be.)
As to what you should do, save often and try stuff, I won't bother writing the whole process step by step. But if want to play thru it and you are stuck, let me know.
