Metadata v31

[commonuserlol]

Hi, sorry for the wrong place for the issues. I am using your PR for Il2CppInspector for metadata v29. Unfortunately most games use the newer version. So fields placed in wrong order and processing fails. Is there any chance that you will look into?

[SamboyCoding]

There is no metadata v31.

https://github.com/Perfare/Il2CppDumper/issues/797, tho Il2CppDumper kinda "died"

Custom engine or something. There is not - as of unity 6 - a metadata v31.

So metadata is obfuscated? I had that with some games, they all using unity 2022+ with error:

The detected Il2CppCodeRegistration / Il2CppMetadataRegistration structs do not pass validation. This may mean that their fields have been re-ordered as a form of obfuscation and Il2CppInspector has not been able to restore the original order automatically. Consider re-ordering the fields in Il2CppBinaryClasses.cs and try again.

Just tried Cpp2IL, works unlike Il2CppInspector

Detected metadata version 29

from your il2cppinspector log

no idea what dumper is doing or where it's getting 31 from but this is just v29

[commonuserlol]

What about minor versions of v29? Can we get exact version (29.1, 29.2, ...) without unity version like inspector does?

[SamboyCoding]

--verbose will log minor version.

I'm talking about il2cppinspector, else can/will Cpp2IL generate stuff for disassembler like Ghidra or IDA?

Custom engine or something. There is not - as of unity 6 - a metadata v31.

I test unity6 and unity 22.3.35f1, it is confused that unity 6 are metadata v29 and unity22.3.35f1 are metadata v31

Cpp2IL now have v31 support
