Emulation Homebrew PS1/2 Emulator ARMSX2-NX Initial Release

Thank you so much for this incredible work!
At what speed would Soul Calibur II and Sega Rally Championship run?"
 
Cool project!
I tried it but for some reason I can't make it read any BIOS, it doesn't detect them in the bios folder (I tried many). I'd love to try Pro Evolution Soccer 6 :D

Will Vulkan be integrated? Is it possible?

I don't believe Vulkan is available through Switch Mesa, but even if it was it would perform worse than the current backend does since it (Deko3D) is custom built exactly for the Switch and it's GPU. OpenGL also isn't supported for the same reason as it's not worth my time to get worse performance out of the renderer.

Based on how other games run, not well, but give me a bit and I can run them and see what happens.

Interesting. I've never had it not detect either of my BIOS' before. As long as it's in /switch/armsx2/bios it should work. Or I believe you can point it to a custom location too if you want to try that. (I also think I left a debug flag in the ini that allows for setting a BIOS file in there that is force used, but I may have taken that out?) It'd be a BIOS= line somewhere in there.

Hey another game that can run at basically full speed!

Also, I've made a spreadsheet outlining the status of each game that's been tested in this thread now. https://cryptpad.fr/sheet/#/2/sheet/view/SwHTSHURcbhL7mLo8aAz3xB+cTKAA3LuIDDhVwkZUd4/

Thanks again for your work on this. I gave "Let’s Make a Soccer Team!" a try (no overclock). I expected it to run more or less fine since it’s listed as perfectly emulated on PCSX2, and I thought the 2D parts might be light enough for the Nintendo Switch. The menus run great as long as there’s no 3D being rendered (like the secretary), but once I get into the simulated matches (even with the 2D field, which I assumed would be lightweight) it drops to around 4 FPS and becomes pretty much unplayable, I guess single core performance of the CPU is not good enough (at least without overclock) for simulating the matches.

Really fun to play with this, thank you so much again

Yeah, performance is really not great on this despite my best efforts. The Switch already has to do extra hacks to get JIT to work, alongside not having some optimisations that upstream has due to Horizon lacking features. I'm both impressed and annoyed with how it runs currently.
 
Yakuza 2 - 8-12 FPS in normal, and 23-27 with max OC

SuperLite 2000 Vol. 19 - Hanafuda: Runs at 100% speed in 2x resolution
Sega Ages 2500 Series Vol. 8: Virtua Racing -FlatOut-: Seems to run at 100% speed in 2x resolution
Sega Ages 2500 Series Vol. 1: Phantasy Star Generation:1: Runs well at 2x resolution, dips to ~70% speed in large areas. Runs at 100% speed in native res but it looks really ugly
Sega Ages 2500 Series Vol. 17: Phantasy Star Generation:2: Same as above
Atelier Marie + Elie ~Salburg no Renkinjutsushi 1 & 2~: Runs at 60~70% speed but otherwise seems completely playable (it's a menu heavy game

tested sega ages outrun (3d remake) and it ran at ~11% speed. space harrier (3d remake) refused to go past the splash screen, but i didn't test it thoroughly

all tested with overclock

A new update just released with version 2.0.0. It can be gotten from here: https://github.com/PalindromicBreadLoaf/ARMSX2-NX/releases/tag/v2.0.0

This brings about a brand new Vulkan renderer that greatly improves accuracy of graphics, and sometimes is more performant than the existing Deko3D backend. Other times it's slower, so it really depends per-game. Vulkan fixes a lot of the present rendering issues, except for Steambot Chronicles. That's got to be some sort of CPU issue possibly also existing upstream. I played through Persona 4 for a good while at basically full speed the whole time with no graphical issues (also with a large overclock).

There's also some changes to the Deko3D backend too, but they're minor enhancements at best.

Hope you all enjoy!

How large was the overclock? Do you think Klonoa 2 will boot with this version?

I doubt it. Nothing on the CPU side was changed. I am working on ARMSX2-refresh currently, which has a bunch of CPU improvements, so that may get it booting. Overclock was 2091/921/1700.
