Crash when trying to run N64 on Linux without Vulkan support

[risingPhil]

Describe the bug I'm trying to run Ares on my Kubuntu 18.04 installation. I built using make -j 12 && make install.

I have an Nvidia Quadro P1000 with binary driver 530.41.03 and I don't have Vulkan support as far as I know.

Yet the application crashes on vulkan stuff when trying to launch a rom, even though OpenGL 3.2 is selected as my video driver in the Ares settings:

To Reproduce I can reproduce this on both Ares v138 and v139.

• Launch Ares
• Launch an N64 rom through Load -> Nintendo -> Nintendo 64 => Crash

Expected behaviour No crash

A crash is rather odd, but Vulkan is required for N64 emulation and it will not work without it; the expected behavior is that you'd have missing or broken video output.

[risingPhil]

I just saw this though:

source: https://ares-emu.net/news/ares-v127--released

Also: I think I may have read somewhere before that Vulkan may be required, but I can't find it anywhere on the website when I actually try to look for it.

I don't know. In any case a crash is unexpected indeed.

I can run the emulator perfectly when I switch to Windows though. But I suspect the nvidia driver there DOES have Vulkan support (although I haven't bothered to verify that yet)

[remutro]

MAME RDP support was discontinued in newer releases and is no longer available. You can't use the N64 core without Vulkan support as it is required by parallel-rdp.

The video options in Settings > Drivers are strictly for putting game images on the screen and don't impact cores directly.

[risingPhil]

allright.

So it appears the only real bug here is that it crashes instead of showing some kind of error notification.

I don't know if anyone is inclined to fix this or not. It's up to you whether to close this ticket or not. I can imagine this to be low priority if you decide to fix it.

Anyway, thanks for responding so quickly.
