The bios file appear in the game list since v1.2.1.

Here's what I tried so far (with an overclocked V1 Switch). I only take gameplay segments into account (I don't care about fps drops or glitches in movies or menus, the speed % is just my visual estimation) :

games running at 90-100% speed :
- Hokuto No Ken Shinpan No Sousousei Kengou Retsuden (J)
- Hyper Street Fighter 2 (AI Nerf v1.0)
- Melty Blood - Actress Again (Japan)
- NeoGeo Battle Coliseum (Europe Australia)
- Sengoku Basara X (Japan)
- SNK vs. Capcom - SVC Chaos (Europe)
- Spectral vs. Generation (Europe) (Enable Hidden Characters v1.0)

70-90% speed :
- Dragon Ball Z Budokai 3 Collector's Edition (E)
- Super Dragon Ball Z (U)(UNDUB v1.0)
- Tekken 5 (Unlock Jinpachi Mishima v1.0)
- Virtua Fighter 4 Evolution (Europe)
- Mega Man X7 (Ns Edition v1.5.2)
- Mega Man X8 (U)(Undub)

around 50% speed or below :
- One Piece - Grand Battle Rush (Japan) : around 30-40%
- Saint Seiya The Sanctuary and The Hades (Europe) : ~50%
- Dawn Of Mana (Undub) : ~50%
- Soulcalibur 3 Arcade Edition Deluxe v1.21) : ~50%
- Street Fighter Alpha Anthology (Europe) : glitchy and slow (~40%)
- Street Fighter EX3 (Europe) : very slow ~30% speed I guess
- Tekken Tag Tournament (Europe) (v1.00) : from memory it runs worse than Tekken 5, around 50%
- Ys V Lost Kefin Kingdom Of Sand (English v1.0) : fps is dependant on how large the area is, it can get very slow

- Ultimate Mortal Kombat Deception (v7.0) : very slow, around 30% speed, the first save took an eternity.

other :
- Battle Stadium D.O.N (Japan) (T-En by Lord Izen v20230906) (Japanese voices) : doesn't boot, acts like a PS2 without a disk.
- Namco x Capcom (Japan) (T-En by TransGen Final Version A) : doesn't boot, acts like a PS2 without a disk


What settings are you using to get Virtua Fighter IV running so smoothly,I'm using a V1 & can't get it to go above sub 15-20 FPS?
 
Really interesting project. I tested NetherSX2 on my V1 Switch and compared it with my NVIDIA Shield TV Pro.

What surprised me is that, in some games, the Switch version performed better in my testing than the Shield. For example, with God Hand, the Switch was already very close to full speed at native resolution, and with Sys-CLK overclocking it improved even further. What surprised me most was that even at 720p resolution the Switch build was still performing better than my Shield setup.

Since the Shield uses a Tegra X1+ and runs Android natively, I was curious what makes this Switch implementation perform so well. Is it mainly the Vulkan path, the loader/wrapper approach, different driver behavior, or optimizations specific to this port?

I'm not suggesting an Android port or anything (If possible that would be awesome) — I'm just curious about the technical reasons why this Switch build can sometimes outperform a native Android device.

EDIT

I tested this using NetherSX2_nx 1.2.0.

After updating to NetherSX2_nx 1.2.1, I noticed that God Hand became unstable. During certain cutscenes, the game would crash and return me to the Switch home menu.

For this comparison, the performance results mentioned above are from NetherSX2_nx 1.2.0.
If god hand becomes playable on the switch my soul will be nagaa's

I was thinking about archiving my Lossless.dll since i couldnt find any internet archive for 3.1 or 3.2 frame gen.
Im half and half on archiving it. But i had good luck with it on Silent Hill 2 and Deus Ex The Conspiracy.

My bad I mixed it up, I get the same results as you do for this game. Sorry for the mistake
