Game Boy ECHO RAM
Hey all! I'm new to the forum.
I've been working on an emulator for some time now, and I just wanted to gather some clarification on whether or not ECHO ram 100% echoes wram. My understanding is that it's the same hardware and that the "echo" is an artifact from the way the ram is attached to the bus. If anybody could confirm, that would be awesome! I'm trying to get every little hardware quirk/bug/whatever emulated properly.
Thanks!

Yes, it's a full mirror. Reading and writing.
