ROM Hack Question Help Identifying File Type

[Skyluker4]

I'm trying to translate a game made in Unity, but I'm running into some problems. Some of the text is inside of a weird binary file that I can't identify the type of from inside an asset bundle. Is it some sort of Unity Script? I'd like to be able to modify the text inside of it and it would be much easier if I knew exactly what I was dealing with. I know that the text is encoded in UTF-8, but that's about it. Here's a picture of the beginning of the file:

First of all where did you get this file and what is the name of it?
Unity tools should show what is it (probably one of Mono) if this is inside one of archives.

And never saw a multilanguage Unity game using so complicated file for texts. This game is only in one language?

The file is inside of an asset bundle for the game Dokapon UP! called eventscript_story. There are multiple files in the same bundle that all have the extension .mes. Not all of the text is inside of this strange format -- only the character dialog is -- the rest are in JSON files in another asset bundle. The game is only available in Japanese.

Turns out the file is a MessagePack, which is pretty much just a serialized JSON file.

@Skyluker4 hi friend, could you show me hở to extract text from asset.bundle unity games?

@Bánh Mì Once you know what asset bundle you want to modify, you need to find the asset(s) inside of it that need to be modified. I used UABEA and AssetStudio to find what needed to be changed and UnityAssetReplacer to batch replace all the modified files back into the bundle. If you need any more help, feel free to PM me.
