In ares, the N64 emulator is unfinished as of the last source release (the RDP rasterizer instructions are unimplemented).
Interestingly, some of its code calls constructors with arguments for classes that are seemingly nonexistent. Take a look in ares/n64/vulkan.
I think byuu stripped code from ares v121 and plans to release a full edition sometime in the future.
It’s also very convenient that almost all N64 games use the RDP to draw to the screen.
This way he can lock away much discussion or hype around the N64 emulator until he comes back with the code and plays a game with it.
He may also not want the RDP code under a license that allows forks.
I haven’t looked at the other emulators inside ares, but IIRC, the N64 emulator was the latest one being worked on.
