Question about depth buffer emulation

[Mr. 64]

I read about depth buffer emulation in the dolphin progress report. Dolphin seems to have a good way to emulate the depth buffer. Unfortunately depth buffer emulation is a big problem for hardware renderers in Nintendo64 emulators. Currently there are two approaches and both have massive drawbacks. It's described in this article http://gliden64.blogspot.co.at/2014/07/depth-buffer-emulation.html?. This is a question to the developers here: do you know a better way to emulate the depth buffer? This would be a big help for N64 emulation. The main problem is that the depth buffer is stored in emulated RDRAM and rendering happens on the PC's video card. I'm asking here because maybe dolphin had similar problems and I see that there are many skilled developers around. Maybe it will be possible play Pokemon Snap with a N64 emulator. Currently N64 emulators only support this game with software renderers.
