damn this is sick, appreciate it!!!

How can I use this on Windows to extract global_metadata.dat from PrincessConnectReDive, the DMM version.

@Krulu

You can’t, because windows version doesn’t use il2cpp. Thus it doesn’t even have a global-metadata.dat.

@esterTion
So it seems like I must run this on android. Can you explain how can I run this to get the global-metadata.dat.
