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.

@gamer56

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

@dankcushions NVM than

@dankcushions thanks

@mediamogul I agree, the nintendo games seemed to run almost perfectly. some minor glitching in shadows etc. but much better than anythign I have seen or been able to do with the pi

Wiimote + Dolphinbar should work with RetroArch emulator cores as of the latest releases of RetroPie and RetroArch.

So maybe I might change the project.

I dunno.

I have a working Wii, but I want to give it to my sister.
Or I could make a new case for the Wii, but I would need to 3d print it.

(someone delete this post please, I might abandon it.)

@geneworld that is only for the nunchuck. Even if it were to work on the nes classic controller only two of the four buttons would work. But im pretty sure none of them will work
