It looks like https://github.com/SamboyCoding/Cpp2IL/issues/305 but here it reached a bit more progress

Can't really do anything with this information. Which game?

commonuserlol commented 4 days ago

The APK is huge due assets (1.9G), I can upload libil2cpp.so, global-metadata.dat and globalgamemanagers, or APK structure is required?

commonuserlol commented 4 days ago

Alright, I'm pretty sure I can (sorry gonna sleep rn) cmdline: Cpp2IL --force-binary-path=libil2cpp.so --force-metadata-path=global-metadata.dat --force-unity-version=2020.3.48f1 --verbose binary & metadata (REMOVE .zip suffix, it's actually .7z archive): files.7z.zip
