Dekopon - (Mostly) Fullspeed 3DS Emulation on Nintendo Switch

PalindromicBreadLoaf said:
A new pre-release version of the emulator has just been released, which may improve performance/fix the freezing/crashing issues present before. I can't guarantee this, as most of the fixes were based on speculation, but I would like help testing to determine if the issues are still there. If they are, please share logs back with me as well as how/when the issue happened, as they are incredibly helpful for debugging.

The new release can be acquired here: https://github.com/PalindromicBreadLoaf/dekopon/releases/tag/v2.1.0-RC1

It is recommended to reset your settings to default and clear your shader cache before running any games in the new version. There are now options in the settings menu to do both of these. A restart after changing settings is also recommended.

(Note: I used AI to help format and explain this report clearly.)

I don't know what kind of magic you worked here, but I’m really impressed with the performance improvements! Most games are now running at a solid 30 FPS. There’s still some stuttering—likely from shader compilation—but it stabilizes once you play long enough.

Before this update, I had to stay at 1x native resolution because the emulator was struggling. Now, games can actually run at 2x resolution at 30 FPS, so I didn't even bother testing 1x since it should easily lock to 30 FPS.

*(Note on Overclocking: I used a moderate overclock—not maxed out, but pushed past standard handheld-safe limits.)*

Here is what I tested so far:

* Metroid: Samus Returns
* 1x + 60 FPS cheat: Very playable (GPU-heavy, needs OC).
* 2x: Solid 30 FPS (needs OC).
* Shin Megami Tensei IV: 2x + custom textures is now fully playable, unlike before (needs OC).
* Pokémon X: 2x runs at a solid 30 FPS (needs OC).
* Project X Zone 2: 2x solid 30 FPS—even battle FMVs play smoothly now.
* The Legend of Zelda: Ocarina of Time 3D: 2x + custom textures + single screen mod works well (needs OC).
* Bravely Default: Runs easily at 2x with custom textures.

Games with compilation stutter or stability issues:
* Kirby Triple Deluxe: Since this game natively targets 60 FPS, it lags/stutters frequently during gameplay, but it's still playable overall.
* Kid Icarus: Uprising: Couldn't test much because it freezes frequently, though it eventually recovers/continues.

Kirby Triple Deluxe runs at full speed with 3x resolution for me with a moderat overclock of cpu and 460mhz gpu. But yes, the shader compilation stutters are heavy. But if you have gathered enough shaders the game is really stable

There were handful of performance things that I broke with the last update that I didn't notice, so that's where some of the performance comes from. I need to look into shaders more to see if there's some way to not have them bog down everything. Otherwise, I'm glad to see things working well!
 
Besides performance being a bit worse, I just figured something.
In Animal Crossing: New Leaf, there's something called HH Showcase. It uses StreetPass so, whenever your console goes by someone with StreetPass on and with this game, their house gets added to the HH Showcase in your town.
Trying to make HH Showcase work, they tell you that you have exceeded the amount of titles with StreetPass enabled you can have. And that you can remove some in System Settings.
After that, a few minutes later while playing this game, a temporary freeze occurred, for just a minute or so.
The time that the reported crash happened, coincidentally I had tried to enable HH Showcase too.

I don't think spotpass/streetpass works whatsoever. At least I haven't touched it at all, so it shouldn't work. I would recommend against ever trying to enable anything regarding either of those, as it's just asking to break something.
 
i thought the freezes only happens on kid icarus, it also happens with other games like metroid, it freezes first then wait a little while it will continue but sudden cpu spike a that it lags so much. so you have no choice just to close the app. and when you open the game again its gone until you hit the freeze again and so on.
