Lakka has made some good inprovments for Gamecube, not sure how good for Wii games, but you need to overclock the heck out of your Pi to get good results on Gamecube

@skyde72 please provide details of your setup as requested.

@pscotto1234 I managed to build the libretro version and sin and punishment 2 ran at like 10 fps. It was just a test. I have an arm-based mac mini for that.

Pi4 at 2Ghz. Bullseye 64bit lite. Latest stable kernel. The last mesa driver I could install was 21.3.x I think. 22 wouldn't build. I managed to build retroarch with vulkan but I couldn't get any emulator to work with it. It wouldn't have helped anyways. I only saw an improvement for flycast when I tried it on batocera which has vulkan pre installed.

@gandalth23 said in Wii emulation performance using Vulkan on Pi4:

I confirm the behavior for Mario Kart Double Dash.

In your other thread you seem to have found a solution for Mario Kart Double Dash. What exactly is the fix? Using that fork of dolphin or the Gecko codes you provided?

Best,
gandalth

The solution to get rid of the blue fog screen is to install the Ishiiruka version of dolphin....

Bonjour, j'utilise retropie sur ubuntu 18.04 et installé dolphin.
tout fonctionne a part que si je met la langue de la wii en francais , a chaque démarrage du jeu avec emulationstation le jeu change de langue automatiquement et repasse en anglais.
sur la gamecube je n'est pas ce probleme
quand je lance dolphin sans passé par émulationstation la langue que j'ai choisi se met bien et reste tel que je l'ai mise, des que je lance les jeux avec emulationstation la langue se modifie et ce n'est plus celle que j'ai mise
Es-ce que quelq'un a déja eu le cas et a une solution
merci

@hackedmacbook111 This is a RetroPie forum, not a macOS forum. Besides, RetroPie is not responsible for developing the emulators, it just packages and configures existing emulators. If you want to run emulators on your macOS, then use the macOS versions of those emulators.

For anyone else looking at using a Wii like this; I couldn't find any reliable sources for the internal dimensions so I measured and did a drawing myself. Hopefully this is helpful to someone...

Ok thanks

@danmed yes I have the .78 romset rom and chd for area51mx running on advancemame and runs well for me. Just a bit of a hitch when entering a new area for instance.

@krullbeast said in can udev read i2c and hardwired GPIO buttons simultaneously?:

do you think it is possible to read the i2c data and also the A and B buttons inside of retroarch?

Not an expert on this, but I think RetroArch doesn't read directly from GPIO (I2C or otherwise), instead it uses an established input driver (udev/sdl/etc.) - https://github.com/libretro/RetroArch/tree/master/input/drivers.

@krullbeast i'm gonna try molten gamepad after i save.

@krullbeast more specifically, can i map the nunchuck(as a directional pad also) C and Z buttons as select and start in emulation station or retroarch AND also have two seperate A and B buttons wired to GPIO pins on my Pi 3b? will they all communicate with the Pi? or will the A and B buttons not work after enabling 12c serial at start up?

i am very new to this, please forgive me if i sound stupid.
and thank you for any advice
this is a rough schematic of what i'm trying to build

@retrotinkerer Wii games will not run on a pi. You'll need much more powerful hardware for that.

Thanks for the update, it's interesting to follow your way to a working solution.

Yeah, it seems that it is a kind of game of chance to get the right BT controllers for the Pi, may it be that I was lucky or you and @gpmcty were unlucky.

And yes, it seems to be either direct connection without the home key, or using an adapter. Ironically, I'm fine with my adapter although I don't use the home key anyway. :)

OK time for feedback. I have succeed to download videos and boxart only, but without game description. How did I do (please, remember that I am on Ubuntu) :

download the latest Stephen's scraper program here : https://github.com/sselph/scraper/releases and put the scraper file into the wii (or the related console) directory list item have your own videos into a folder named for example videos download boxarts on libretro project : http://thumbnailpacks.libretro.com/ and put them into a folder named for example boxart make sure that iso names are EXACTLY the same as boxart and videos names use Krenamer or any other batch rename program to rename :
-boxarts : add -imagesuffix before .png extension
-videos : add -videosuffix before .mp4 extension put all boxart and video files into the same folder named images (very important) then open a terminal and go to the rom directory cd /RetroPie/roms/wii/ and put the following command : ./scraper -add_not_found=true -download_videos=false -img_format=png -download_images=false. For your information :
-add_not_found=truemeans it adds roms that are not found as an empty gamelist entry
-download_videos=falsemeans it checks the local videos only
-img_format=pngmeans it checks the png files (because default check is jpg)
-download_images=falsemeans it checks the local images only

I've been running PCSX2 for a while, it is heavily optimized for Windows and you are going to have a significant performance drop unless your machine is a beast.

Ideally, you should also be several feet away. The DolphinBar sensor and even the AimTrak become overly sensitive if you're located too close.
