Support for 6000.3.x?

[cheesekewb]

Quick background: A friend of mine designed a program to data scrape a game that, of course, relies on this bridge utility. It's always worked fantastic and for that I'm extremely grateful, because I've used this data to maintain player resources/wiki for the particular game for about 2-3 years now. However, upon trying to grab data from the game's latest update, I discovered that they upgraded their unity to an extremely recent version (6000.3.3f1, apparently released January this year), which is certainly a curveball...

All I'm curious about is if I could expect this utility to be updated to support those versions in any near future. My honest guess is probably not, but I wanted to open the floor just to be sure... There honestly may be zero demand for support of versions so recent and my case feels like a total one-off at the moment. But, the friend who worked hard on the program might be open to designing a hotfix -- so with that said, any tips or guidance on trying to create a hotfix would be appreciated as something to pass onto them, if they do find the time. Thanks much :)

Hi, I still hadn't the chance to take a look at newer Unity versions - however, did they break something?

[cheesekewb]

At least in my particular case, yes, it seems so.

When running outright, it'll say it can't figure out the version and to specify manually. However even after doing so, it says "Error: Malformed package", and this:

script.post(message);
             ^

TypeError: Cannot read properties of undefined (reading 'post')

To be clear, to specify the version, I had added this line:
Il2Cpp.$config.unityVersion = "6000.3.3f1";

I did try specifying other Unity versions just outta curiosity it might work, but it still gives the same malformed package error regardless.

Uhm, I'm pretty sure it's not related to frida-il2cpp-bridge - it's likely to be a Frida or process thing

I get il2cpp: couldn't determine the Unity version, please specify it manually only on unity 6000.0.xxxx games

[vfsfitvnm]

That's unfortunate. I could not find any other way to detect it

[StumbleTTAdmin]

I managed to fix it by adding Il2Cpp.$config.unityVersion = "6000.0.68f1"; thankfully but some tools like the dump tool to dump the il2cpp csharp files still give the error guessing because i would have to add the same line to whatever script the dump parameter uses to dump the files

[vfsfitvnm]

are you referring to frida-il2cpp-bridge cli? if so, you can pass --unity-version 6000.0.68f1, or --script-prelude your-file-with-whatever.js

        group.add_argument(
            "--unity-version",
            required=False,
            help="Unity version in case it cannot be detected automatically",
        )
        group.add_argument(
            "--module-name",
            required=False,
            help="IL2CPP module name in case it cannot be detected automatically",
        )
        group.add_argument(
            "--script-prelude",
            required=False,
            type=Path,
            help="path to .js script to be executed before running command-specific code",
        )
