@standarsh14 said in RetroArch won't distinguish between two controllers:

It seems like either controller will work with one registered bluetooth connection - which confuses me because I thought that with separate Serials, only the one registered would work.

That's unexpected, the controllers should have different MAC addresses (they appear in the pairing dialog) so the OS would be able to tell them apart and some pairing info to be also stored on the device itself. Deleting the device from the list of paired Bluetooth devices in RetroPie should force the gamepad to be re-configured.

With both devices connected, can you run

cat /proc/bus/input/devices

and post the output ?

You can also test with jstest if the controllers are acting separately. Run:

jstest /dev/input/js0

and press the buttons on 1st, then on the 2nd controller. Only one controller should yield any events/output on the test.

You can use an external application for that (Twitch/Discord/Mumble), if you want to host a chat server (since RetroArch doesn't offer this functionality at this time), then use Mumble to host your own chat server. You might want to get a separate PI for the hosting the server, since the Pi might not be able to drive both the emulators and the voice/chat server at the same time.

@yfzdude said in MAME query re: picking characters on 4-player games? (TMNT, Simpsons etc):

Rampage also matters. (3 Players)
[I think the order was George/Lizzy/Ralph.]

They made sequels to Rampage. (After ten years) But they were basically the same gameplay with different characters.

https://en.wikipedia.org/wiki/Rampage_(1986_video_game)

Only the P1 controller has access to the Hotkey, so you can do any configurations for a game in the RGUI with a controller that has a hotkey defined (the one you chose when you configured the controller in EmulationStation). Make sure that controller has also an X button configured, otherwise you can't open the RGUI with the Hotkey + X combination.

To enable Multitap - and get more than 2 players working - you can do so from the Options menu, where you need to toggle on the Show other input settings, close the RGUI, then open it again and in the same Options menu, can set _Multitap_1 to ON and Pad 2 to Pad 4 to dualshock.
Since not all games support Multitap and enabling it globally would probably break input for it, make sure that you use the 'Create Game Options file' menu at the top of the Option list, then toggle off the Multitap option(s).

According to your diagram, if you swapped where P2 and P3 stood then you can have the same shader on all the games and things would be "smoother" with the video orientation being same for all games.

Yes, it requires some setup but it's working on my Retropie on a Raspberry Pi 3B. Loads of fun and laughs with the mates, strongly recommended.

4.2 is very old release, you should update to a more recent RetroPie version, as we cannot continue supporting such old version.

Super Mario Bros. Deluxe
Pokémon series

no news??

Thanks a lot.

By the way. Is there any work around, I am thinking of for example being able to point out a specific (older) version of a binary to install?
I guess this could be good also in the case when several clients happen to run not the latest version of a Ported game (multiplayer), and then a new client installs the game but runs into compatibility issues when joining the multiplayer game.

I have recently started using 4-player games on the SNES emulator. I can tell you that I had to install and use lr-snes to get it working right. When I would try to use lr-snes9x2010 the player 2 controller would simultaneously move players 2 - 4 at the same time.

As quicksilver said, the best way to handle it is to save overrides for the specific games. I also saved the alternate emulator as the default for those games only. I have successfully gotten 4P to work on Super Bomberman 1 and 2, NBA Jam and NBA Jam TE for the SNES.

@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.

@philipmather ditto /opt/retropie-player1/e...s.../scripts/inputconfigurations.sh has hard coded rootdir.

@chris52 P.S. Ill be using the command line codes for netplay to actually achieve the link between the database and multiplayer functionality. I just need help editing the menu.cpp file as it is hard coded and I don't quite understand the addEntry functions and have found limited documentation. I understand that I must decompile and recompile the file.

Solved. It was problem with my rom. I've downloaded the new one form the internet and it works fine.

@mitu said in Splitwolf: 2-4 player co-op Wolfenstein 3D on RetroPie:

@f33dbacknz The error printed during installation can be fixed by installing the rename package (via sudo apt install rename). Try installing it the package and then re-run the installation for splitwolf.

It should be added as a dependency of splitwolf then.

@quicksilver Thanks for the summary. I found these threads from you about overclocking:

https://retropie.org.uk/forum/topic/16155/overclock-stability https://retropie.org.uk/forum/topic/16930/overclocking-discussion https://retropie.org.uk/forum/topic/17544/core_freq-vs-gpu_freq-n64-performance

and this thread by @thelostsoul that you participated in:

https://retropie.org.uk/forum/topic/17032/stresstest-a-fanless-overclocked-pi-3-b-no

I will read them in my next spare time.

First, you should provide the information asked in https://retropie.org.uk/forum/topic/3/read-this-first.
Second, you might have stumbled upon the news Sony driver behavior in newer kernels, where the rumble appears as a separate device and messes up the controller numbering. See this topic for a workaround.
