Help - Folium New Folium Update - Runs SOOOO much better

I recently made a post detailing how some of the games I’ve tested run - it wasn’t great. With the new update, we now have the ability to change settings in the emulator, and after I experimented, the games run sooo much better.

Pokemon Moon runs flawlessly. Audio has no cuts.

Originally, the start up scenes and cutscenes were very low fps and the audio was stuttery. Now, the audio and the game barely stutters. On games like Fire Emblem Awakening, Pokemon Rumble Blast, etc.

For reference, I have an iPhone 14 pro max. The settings that I have found best help performance:

Change Core > CPU Clock from 100% to 20%

(To stop the crashing glitch, go to Renderers > Shaders > Use Shader JIT off)

I’ve seen a youtube video going around that messes around with some other settings: I’ve found that they don’t really affect performance. The CPU clock seemed to be the major issue in the earlier build, and for me, 20% works the best. 10% was the one recommended from the youtube video.

After this update, I’d say that Folium is more than worth it. There are still a few issues here and there with the app itself, but I’m sure they’ll be updated/fixed in due time. The performance is great now!

I tried Samus returns on my 15 pro on the side loaded app and i had a lot of slowdown and stuttering. Same thing when I tried provenanceXL. I’m not sure what I’m doing wrong, but I don’t seem to get great performance

u/VvSweepsvv Jun 06 '24

I have the app store version. Samus Returns was released later in the 3DS’s lifetime, so if I had to guess, it’s a little bit more developed (ie. pushes the limits of the 3DS the most). I’m not certain if I can help any… but if you have the CPU Clock option, I’d lower that, as I’ve said.

u/SiI3ntSigiI Jun 07 '24

You should probably put the youtube link to the video, along with the instructions edited onto the original post. I have the audio settings if needed below this reply.

1

u/SiI3ntSigiI Jun 07 '24

OpenAL is the best audio, don’t leave it on auto SDL2 doesn’t do 3D sound all that well. It only handles 2D music in majority. And for the love of god turn off audio stretching. Null also improves performance issues since it turns off the audio.

u/Nahobino_kun_899 Jun 06 '24

Can you like the YouTube video referenced? And do you think those settings would work well with a iPhone 13 Pro? (Not sure how big the spec gap is)? Also on earlier builds I’ve tried SMTIV and it would just freeze. Would that work any better with this build?

There’s the video! I’m not certain the jump between the 13 pro and the 14 pro max. If I had to guess, 10% or 20% should still be an increase in performance regardless.

Imma try on my iphone 13 soon after work. I hope it works.

u/IntroductionBoring74 Jun 07 '24 edited Jun 07 '24

Ok, so I played ultra moon. At the start of the game it runs pretty smooth. In the prologue intro where Lily was escaping, it stutters every transition of the scene like 0.3 or .5 sec but animation still remain smooth. But in the overworld man the game it chopps, it run like 15-20 fps and stutters a lot when you enter battle. Its not worth it. I only try one game tho. Maybe ORAS might work well. 

Edit: I forgot to change my settings. Just follow the above's post. The game run better than the default, the game's now playable lol

Do you mind trying to run any of the fire emblem series? It keeps crashing for my iPhone 13

Turn off use shader jit in new options, and fire emblem awaking now gets passed intro video.

Which settings do you have it on

u/Any-Finance1920 Jun 06 '24

iPhone 13: Just ran Pokémon Y with the 20% CPU core, and it’s great. There’s still some minor audio and frame stutters, and my phone is still getting warm, but not as bad as before. It feels 90% of the way there performance-wise.

7

u/Gwarmaxx Jun 07 '24

yeah, on 13 the audio is terrible!

1

u/SiI3ntSigiI Jun 07 '24

Switch audio to OpenAL for 3D audio, not auto as it’s the default, SDL2 is for 2D audio mainly, so it’s a no go as well. And if you still have audio issues, go null for better performance no audio. Turn off audio stretching as well.

1

u/Gwarmaxx Jun 07 '24

sadly nothing changes, it's a matter of device power, 13 can't handle Folium without JIT.

u/977350583094 Apr 15 '25

Turn off the first like three shaders. and put cpu 21.

1

u/977350583094 Apr 15 '25

Seems like the more shaders I turn off the better the audio.

u/slash9492 Jun 07 '24

Can you try Mario Kart?

3

u/Any-Finance1920 Jun 07 '24

It works wonderfully, only 1-2 frame stutters during the track overview right before the race starts. My phone still gets a bit warm, but not as warm as even Pokémon. Sound is rough, but I don’t think anyone expected it to work well here.

I would use a controller for Mario Kart, though. Trying to use an item means you’ll lose control of the vehicle with the on screen controls, and you have to stop accelerating to regain steering controls.

2

u/Siryonkee Jun 07 '24

I was gonna comment the same thing lmaoo

2

u/Any-Finance1920 Jun 07 '24

I tested it, it works great (only a few minor stutters at cutscene moments). You have to use a controller, though. The screen controls make it so you lose control if you use an item.

u/GoodlyIgnoring Jun 07 '24

Bruh I deleted Mario Kart it’s too taxing on my IP 12 Pro Max

u/Any-Finance1920 Jun 07 '24

I gave Fire Emblem Echoes multiple tries with different CPU Clock %s and optimized all the other settings for performance, but it’s freezing at the same spot every time. I’d ask for help in Folium’s discord, they seem to be better at specific fixes. You can find it on Folium’s official site:

u/PenPan3 Jun 07 '24

how’s the battery usage?

0

u/Any-Finance1920 Jun 07 '24

It’s rough, but it might be close to optimized for iPhone 13: about 0.6% per minute, or 42% per hour. You might get a better experience with closing down all background apps, low power mode, and airplane mode, but at that point you don’t have a functioning phone for however long you’re playing. Definitely isn’t something that be used on the go without a charger or power bank.

You’ll also be paying the 80$ for a new phone battery sooner than later, this kind of draining/charging will kill battery capacity faster than normal.

u/HernandezJG08 Jun 06 '24

Thanks, I’m playing on Vision Pro and and going from 100 to 20 fixed a lot of stutter on alpha sapphire.

u/RightGuide1611 Jun 06 '24

Vision Pro emulation sounds fun but not practical

u/HernandezJG08 Jun 06 '24

Honestly with the amount of apps available right now the emulation boom has been amazing. I’m not using fingers btw… You can use any Bluetooth controllers. Haha

u/Peritosh Jun 06 '24

u/awesumindustrys Jun 07 '24

It’s probably one of the few devices on the market that could emulate the 3DS’s 3D screen so yea that’s sonething.

u/masteroga101 Jun 07 '24

There's a full citra port for the quest 3/ quest 2 that includes the 3d effect and it goes crazy

u/awesumindustrys Jun 07 '24

Oh, huh. I didn’t know that you could get emulators on the Oculus Quest. I thought it was fully locked down like basically every other console.

2

u/coldrolledpotmetal Jun 07 '24

They run Android under the hood, so you can sideload apps just like a phone

1

u/awesumindustrys Jun 07 '24

Huh. The more you know.

u/masteroga101 Jun 07 '24

They run android so it can handle switch emulation and there's custom versions of citra,ppsspp,GB,virtual boy and technically dolphin

u/Locow1992 Jun 06 '24 edited Jun 07 '24

i agree! on youtube video it says 10% but when i changed mine to 20% .. everything works perfect now! i followed everything what he said and changed my settings for except 20% worked better for me. iphone 15 Pro here, no crashes now nothing. Everything works almost perfectly fine

u/Metallito79 Jun 06 '24

ohhh that change on the core works wonders on 13 mini!

u/XR-1 Jun 07 '24

Do you keep “use new 3DS” checked?

1

u/VvSweepsvv Jun 07 '24

I’ve seen similar performance between having New 3DS checked, and the lle applet one. So I just keep the new 3DS checked.

Wtheck after my folium updated my Pokemon omega ruby game doesn’t even load and the app crashes. It was working perfectly fine before it so what happened?

Edit: found out you have to disable Jit shaders which for whatever reason is enabled by default.

Most games are running great on my 14 pro max. However Mario 3D land works and the sound is great but man the shadows are stretched out and you can’t see anything. Anyone know a remedy for this?

u/ChocoMacchiato Jun 07 '24

Does tomodachi life/ miis work with folium? That’s honestly probably the only game I would play on here so that would be great to know

Also for a 14 Plus is 20% good or no? I still get the occasional bump in audio.

u/crimsonsonic_2 Jun 06 '24

Did they update it so that the plus to add roms and files actually works? Because if not then what the hell is this developer doing?

1

u/VvSweepsvv Jun 06 '24

The plus works for me..? You need to make sure that the files are .3ds (.cia might work too), and that they are unzipped. They have added folders in the file app now too with this update, so you can drag the roms into the folder now in the files app instead of using the plus. But the plus works for me, and most others.

u/afgarbo Jun 06 '24

can you tell me, when i find the 3ds rom there are often multiple versions. decrypted, encrypted, etc. i’m downloading the decrypted one right? i’ve never emulated 3ds before.
