Only this (reicast 2 players)[solved]

[mauruco]

Hi all,
I am very happy with retropie 3.7! That's incredible! Thanks All!
I switched lr-PPSSPP by PPSSPP (better).
I changed the place of the savefile retroarch.cfg and mupen64plus.cfg to /media/usb0/savefile/ (reicast, ppsspp simlinks trick ;) )! I turned off the bluetooth PI3 and I am using my bluetooth dongle again to avoid freeezers. I will add a very cool splashscreen (https://github.com/israelperez/retro-gaming/tree/master/theme/video). Only one thing can not do. Place 2 players to work on Dreamcast. I think I've tested all the settings that is the web but nothing helped.
Any idea that can help?
Thanks

Hello,

Reicast emulator version is compiled for one user (it's not an option).
You have to recompile code source on your raspberry.

Read this, it's really easy :
https://retropie.org.uk/forum/topic/144/dreamcast-reicast-and-2-xbox360-controllers

And you can download source code here :
https://github.com/RetroPie/reicast-emulator/tree/retropie

For information : multiplayer will not work very well with split screen. But you can play Soulcalibur, power stone and virtua tennis for exemple, it's OK.

But from this repository (https://github.com/RetroPie/reicast-emulator) worked.
Thank you very much! Now everything is perfect!

thanks, successfully compiled it and soul calibur works in versus battle mode (2 players)!
download source from here:
https://github.com/RetroPie/reicast-emulator

just be sure to compile reicast in the /usr/local/bin/reicast directory and first install all the developer buildings before you type and enter "make clean && make":
sudo apt-get install
libasound2
libegl1-mesa-dev
libgles2-mesa-dev
libasound2-dev
mesa-common-dev
libgl1-mesa-dev

in the end you'll get two files in the shell/linux/ directory. you just need the reicast.elf. but rename reicast.elf to reicast (without file-ending) and copy it over to /opt/retropie/emulators/reicast.
but make a backup before you replace the old file.
