Thank you, thank you, thank you.

I looked up how to get into service mode and is f2. I have my hotkey input_save_state set to f2. One time, I must have not hit the hotkey.

And now I'm going to re-map these buttons.

@tackett1980 Cool.. you know, I'm just gonna say the difference in bios files might be a wild goose chase.. so only search for mine if you're really bored :P Hopefully the reicast folks will address the build issue with the stable branch on rpi3.

@mitu switching the controller to the switch mode, which I didn't realize would even pair, fixed the loading issue. Crazy!
It does introduce some input lag but still very usable.

Thanks so much!

Try using the Sound configuration in the RetroPie system (or using raspi-config) to force the sound on the HDMI or the 3.5'' jack.

This is a RetroPie dedicated forum, I don't think this topic belongs here - though some of the forum users might have a 3DS and some experience using it, you'd be better off asking in a dedicated Nindendo 3DS forum.

I'm using the following setup:

Raspberry Pi 3 Model B
RetroPI: 4.5.1
Retroarch: 1.7.6

@dankcushions said in Best way to set up multitap?:

@lesk no, each system page in the wiki will have specific instructions to set up multitaps for a given system. eg https://github.com/RetroPie/RetroPie-Setup/wiki/Playstation-1#multitap-3-5-players

Sorry for late reply, but thanks! As I understand it, for the playstation you have to do some manual changes for each games that dosen't support analog etc.
But for Snes, Nes, Sega and Arcade I can just go in via the retroarch menu while playing a game and add multitap support and core save.

@mitu
Let's say 1 Gb.

Got it thank :)

@spaniel48 We don't support 3rd party images, especially the ones sold with the hardware/roms.

@rsn8887 we can't control were RetroPie users will open issues - they're welcomed to open them here and we'll help them as far as we can. As for releasing an image, that's a work in progress - but users can always update from their packages from an existing installation.

if its available for rpi4 try installing drastic-ds youll need a keyboard connected to my knowlage to correctly map the inputs the first time round but it runs brilliantly even on a pi3

The message about the controller being detected / configured means that RetroArch starts ok. Can you try and enable verbose logging from the Runcommand launch menu when running the game, then exit the game and copy the /dev/shm/runcommand.log file over. Post it's contents on pastebin.com to take a look at what might be the error.
You'll probably need to enable SSH and use WinSCP to copy that file, since it's not available via file shares.

My problem with that solution is the available HDMI splitters are all much too large. Adding a HDMI out port to the case will take a lot less space. I'm using these with 20cm ribbon cables inside the casing and they are quite small.

@Gameeplayhard you can install KODI and play all the movies you want from your harddrive

Oh that's interesting. I'm using the default driver, I guess rotation did not work for emulationstation when it was done through config.txt. However adding the --screenrotate, it definitely worked.

I'm also looking at the script they provided to set it upt.
https://github.com/goodtft/LCD-show/blob/master/MPI4008-show

sudo echo "dtoverlay=ads7846,cs=1,penirq=25,penirq_pull=2,speed=50000,keep_vref_on=0,swapxy=0,pmax=255,xohms=150,xmin=200,xmax=3900,ymin=200,ymax=3900" >> ./boot/config.txt.bak

Guess I need to be using the ads7846 driver instead of the default one. For now I'm just happy it worked. Thanks.

@mitu Awesome thanks. Will let you know when I do.
