EKA2L1 VS MoltenVK

EKA2L1 (https://github.com/EKA2L1/EKA2L1) is the main Symbian/N-Gage emulator I'm aware of. It works perfectly fine on PC with the games I've tried, but scaling up the already low resolution of the display to PC resolutions, especially with the 3D stuff, is pretty painful.

They're really a web search away. You might be interested in the EKA2L1 emulator and this handy guide from UESP if you feel like playing Shadowkey, but I can't help you with for the game itself.

The EKA2L1 emulator came out more recently so now you can play actual N-Gage games. There’s an UESP guide for getting set up with it which worked for me when I tried it, but idk if it’s been updated or needs updates though. You’ll want to check out these files as well.

CBNK3D is also avaiable on Symbian devices and can be played on EKA2L1 emulator.

If you want to emulate Symbian stuff, I suddest you use the EKA2L1 emu on a 64-bit/ARMv8 Android device for best compatibility. And get a Bluetooth gamepad for the best experience as well :)

Yes! Look here: https://12z1.com/

Translating between rendering APIs is not really the problem. The GPU design is more different than the API is.

Khronos maintains MoltenVk though, which is "official" as it gets: https://github.com/KhronosGroup/MoltenVK

...technically, Vulkan on Windows is also only supported via 3rd-parties (the GPU vendors), Microsoft doesn't support Vulkan either ;)

MoltenVK implements large parts of Vulkan on top of Metal for Apple systems. It isn't full Vulkan but it makes porting Vulkan games to OS X easier.

That's cool. Maybe I haven't thought enough about this. Let me check it out. FWIW it's this PR that you are referring to I think: https://github.com/KhronosGroup/MoltenVK/pull/1815/

For Metal specifically, they could adopt and contribute to Vulkan and get access to a lot more software. Right now you need to use a compatibility layer, and surely Apple could just support both APIs natively with much lower overhead. But they don't, because it nudges developers to stick to the Apple ecosystem instead of being able to support multiple platforms.

At the moment the most promising thing is MoltenVK (DX12 -> DXVK -> Vulkan -> MoltenVK -> Metal), but the development is not that quick mainly because there aren't tons of developer that works at the same time on the project. It's not actually a Metal related problem at the moment (they have a road map of things that they can be achieved with Metal 3 like Mesh shader and Geometry shader).

What you asked is already existed for at least 8 years. Yeah EIGHT years. It's called "MoltenVK". So far it's the only implementation of Vulkan for macOS. Basically it's a wrapper that runs on top of Metal API.
