I read the install/patching instructions which said it is for 3.04. Skimming through the thread here I see mentions of a bob translation, is it coherent or is it a standard machine translation?
They meant to say that the content from part 1-2 are merged with part 3 so yeah you can play until the big choice of faction with the human english of these part but after that you need a mtl translation.
I think they are working on the Alice route at the moment so you can try playing this one but the translation is not even finished for this one and it's not even 1/3 of the content of part 3 (more like 1/4 of the content)
So yeah, most people have played and finished the game with some mtl tool like mtool or chatgpt translation with some human correction for the worst thing like gender miss for Luka called a She.
The bob translation is the better one because the guy put a lot of work on it with the help of some people on discord so it's pretty good and easy to use (just use the game exe and play)
The mtool one that most people, myself included, used at the beginning is the worst one but mtool is mostly a powerfull cheat engine that let you cruise on the content.
Before 3.02 the chaos route was pretty much impossible to play without 20-30h of grinding and optimal team, with random fight ending in 5- 10 turns and mimic being a game over most of the time.
Now the game give you the option to get a key item to give the monster 1 hp/atk/def/agility so you can have a good experience during the chaos route.
So at the end of the day you can play an ok version with bob translation or wait 1 year for the human translation to finish the translation and it's not even sure you can get one with this time.
Your choice.
