Forking a repo is not the same as developing it. Any idiot can rehost the existing source code, but all the developers with knowledge of the code base and project just got axed by Nintendo.
This fork doesn't even have the code for the dynarmic submodule under the externals/dynarmic directory. MerryMage/MerryHime took that down with Yuzu, and it's a core part of the JIT recompiler.
Not to mention, the commit history was wiped clean while a new Patreon was created before even touching a line of C++ code (and subsequently realizing it's missing most of the dependencies).
