Cemu Thread: Emulating Wii U Games

Heh, I laugh at how much of a n00b I am at this sort of stuff. I see why I confused you. It's not DSR is it, that's a custom resolution I was using. Using DSR now (6880x2880) and yeah don't have to worry about refresh rates now..sweet. Thanks.

Cheers.

Yeah, and in case you missed the guide I created, you can go beyond the max DSR resolution that you can set in the control panel. As well as create resolutions in any aspect ratio you desire.

I always feel this stuff is overwhelming and too technical but I think that's partly an excuse for my laziness and impatience :) You make your guides pretty easy to follow. I'm just thrilled knowing I can enable DSR through my desktop resolution (3 years too late!) and it's lessened the nagging feeling that I could have done better. Appreciate the guide, cheers.
 
havent been keeping up with Cemu at all but its nice to see BOTW having massive performance
albeit at the cost of other games, bayonetta?

how possible is 60fps for BOTW, or is the framerate tied to game logic or physics? sorry if the question has been asked multiple times

I think it is, so no 60fps.

The entire game speed is tied to framerate it seems. 15 FPS is actually only going to run at half speed, whereas 60 FPS is double speed. So you have to cap to 30 for a proper game experience. I'm not to knowledgeable when it comes to modding games but it's safe to say that 60 is very very unlikely to ever happen.

Whoa, thanks for this guide, Jim! I've been wondering for a while now how to get past the DSR limit.

Glad you found it useful :)

I only ever really posted about that in the PC Screenshot thread so it's probably not a very well-known trick. Maybe I should post it on Reddit or something.
 
Haven't kept up with updates, but is Zelda fully playable (no game physics etc bugs)? I'm currently playing it on the Switch, but wouldn't mind transferring the save and playing on PC in 4K whenever at home.

Someone over on r/cemu posted about a BOTW trainer. From my brief testing, it looks promising.

Oh wow, this trainer just made this the definitive version of Zelda!
 
It's completable from start to finish, yes, but it's not what I'd call ideal yet.

What's not ideal? Or what's not working correctly?

When a game is running, look at the Cemu window title bar, there'll be [SaveDir: xxxxxxxx] these folders are located in <cemu folder>/mlc01/emulatorSave

Real Wii U saves work in Cemu, you'll need homebrew to export them

Wait, can switch saves be used for Cemu?

It's generally just a lot of small performance/graphical issues that add up. It's not ideal if you're looking to load it up and start a first playthrough.
Cemu is a Wii U emulator, nothing from Switch would cross over.

That was so easy to set up! Just playing around with the smoothness setting because some of the higher resolutions beyond 6k were looking a bit soft to me for some reason. Thanks again.

You are aware that people don't use this just for Zelda, right? Anyway, not at the moment since Switch savefiles have no public extraction method AFAIK. Then, it would depend on individual games' and equivalents save structures. Maybe they're identical, maybe they're convertible, maybe they're not.

Glad to hear it. I like to make guides as easy to follow as possible, so if you think anything could have been more clear let me know.

The default smoothness is too high for me. I like 23ish.

Nah, your instructions don't come easier or clearer than that to follow. So yeah 21 seems to look good to me and better than the default 33.. cheers.
 
I know CEMU is heavily CPU dependent, but in Zelda BOTW could I theoretically see any performance gains going from a 980 TI to a 1080 TI? I'm debating upgrading, and if it provided any benefits to CEMU it would push me over the edge.

980TI is already a bit overkill for CEMU, don't consider it a deciding factor for GPU upgrade.

No. GPU power basically matters very little to CEMU.

It is unlikely you would see any performance gains. I didn't going from a 970 to a 1070.

If you don't already have a top-tier single core performance CPU, then you'd be better off spending that 1080ti money on a new processor instead. Otherwise, there's nothing else you can do for BotW right now. Even at 5K, my 980TI wasn't being full utilized in BotW. So a 1080TI would do nothing.
 
After playing on Switch for a while and going back to the Cemu version I noticed there is a lot of particle effects missing as well as the distant fog, still looks lovely at 6k but I hope they can add in the rest soon.

Dying to play through it again with my elite controller.
 
1.8.0 just dropped, breaks shader cache compatability by implementing a new system.

Code:
# Cemu detailed changelog for 1.8.0
# Patreon release date: 2017-05-23
# Public release date:  2017-05-30

general: Added memory scanner (search and filter for values)
general: If Cemu is maximized to fullscreen, it will remain on the same monitor rather than defaulting to the primary monitor

RPL: Optimized loading of RPLs

GX2: Cemu now uses separable shaders
	 Vertex, geometry and pixel shaders are split into separate and independent programs rather than bundling them into sets
	 This change breaks compatibility with pre-1.8.0 shader caches and graphic packs (if they contain shaders)
	 
GX2: Added support for using the same texture multiple times with different sampler parameters during a single drawcall
GX2: Graphic pack texture rules will automatically scale gl_FragCoord
GX2: Implemented shader instructions RECIPSQRT_FF and RECIP_FF
GX2: GPU7 shader decompiler will output slightly more optimized GLSL code
GX2: Better detection for invalidation of data in Streamout cache
GX2: Optimized frequently used GX2 API
GX2: Optimized texture decoding
GX2: Added command line option '-nsight' to allow debugging via NVIDIA Nsight
 
For now, I assume no, since it breaks existing shader caches required to alleviate stuttering.

In the long term, I think it's a good thing.
Meh, creating a new shader cache was never a problem, a few hours running the game and you had most of it generated. The stupid RAM requirements for them was the problem.
 
So is it any less glitchy and does it have the missing particle effects for BOTW yet?

Will check it out in the morning after my nightshift.
 
Be aware that GPUfenceskip will not be enabled on this unless you add it into the profile. So your fps will likely tank from 1.7.5.

Edit: More clarification, I mean your fps will be probably half of what it is with gpufenceskip enabled. Good news is that v80 seems to load now, bad news is I put my WiiU in the closet.
 
Meh, BOTW still crashes like a bitch for me in 1.8.0. It seems to be getting worse the more I progress, wasn't nearly as bad earlier on.
Not sure what I expected though, obviously they didn't advertise any improvements on that front but still :p

As part of the graphical fixes, I think botw's built in AA now scales properly to the screen, ironically making it more noticeable regardless of resolution.
 
Have they fixed the problem with zelda botw random crashes in 1.8? I found it nearly unplayable in the last cemu version due to the crashes happening all the time (sometimes every 60 minutes, sometimes every 5 minutes)
 
Tekken tag works even worse than ever in 1.8. It literally plays at about 50% speed, has more graphical glitches, and still crashes whenever you hit tag. This emulator seems to be going backwards instead of forwards

If that's the extent of what you've found, pretty sure that makes 1.8.0 a net positive. Game performance is an issue on your end though, it's pretty easy to have scenarios at full speed.
 
How is it an issue on my end when all previous version ran at normal speed?

Because it's not an issue for me? What's an instance of a new graphical issue or specific scenario where there's a performance regression you're pointing out? Main menu? Character editor? Specific character or stage? Again, you're pointing out a single game, if we swapped version progression, you're still saying you prefer 1.7.5, a version with much more bugs and doesn't even load the newest version of the most popular game to be emulated on it.
 
Does anyone else ever see the ground texture in Zelda BOTW get replaced by a checkerboard rainbow pattern? It never happens right away but usually after playing a bit it eventually appears...
