emulator in dual mode

Can you please share what did you find to pay GB in dual mode?

@ironic a friend of mine made an awesome ahk program to move all needed files to launch .uae whdolad files.

http://arcadespain.info/Foro/index.php?topic=5112.0

I want to use a 4" vertical display and pifba is the best performance emulator for neogeo.
But I have a problem when I set the option "RotateScreen=1" loading screen is perfectly strectched to full screen but ingame is showing 4:3 and only on 30% of total screen.

This is my setup:

[Graphics]
DisplaySmoothStretch=1

Display Effect: 0 none, 1 scanlines

DisplayEffect=0
DisplayBorder=0
MaintainAspectRatio=0
RotateScreen=1

Is there any alternativa to the gameboy2.glslp shader?
Looks amazing but all games runs slowly and with soun glitches.
I,m on recalbox 4.0.1 and rpi3.

@ironic Here is my openmsx config for recalbox.

1. I´ve created a folder on : /usr/emulators/openmsx/bin/
   I put my openmsx binary file form retropie inside.
   Here you have the link
   http://s000.tinyupload.com/?file_id=22889548546368582728

2 . This libraries are needed to launch the emulator.
Put them on /usr/lib
http://s000.tinyupload.com/?file_id=15973386028963335785

3. Launch the emulator with ./openmsx

4. After first launch go to /recalbox/share/system/.openMSX/
   Put all this files inside the folder:
   http://s000.tinyupload.com/?file_id=17148959869931873621

5. Create a folder on /recalbox/share/roms/msx inside it you have to put your Msx roms

6. Finally edit the file /recalbox/share_init/system/.emulationstation/es_systems.cfg

Adding this lines:

<system>
<fullname>MSX OpenMsx</fullname>
<name>msx</name>
<path>/recalbox/share/roms/msx</path>
<extension>.mx1 .MX1 .mx2 .MX2.rom .ROM</extension>
<command>/recalbox/scripts/runcommand.sh 4 "/usr/emulators/openmsx/bin/openmsx %ROM%"</command>
<platform>msx</platform>
<theme>msx</theme>
</system>

P.D. Maybe you need chmod 0755 -R to all files and folders and chmod +x to openmsx binary file.

I´m using the same folder for two diferent emulators.
I renamed the two files and manually added them to my gamelist.xml
Thanks.

Thanks @ironic i´ll keep trying.

P.D: I´ve get openmsx to run on recalbox , I´ll share my config if anyone is interested.

I've made a mistake and hide a few roms from the emulationstation menu.
How can i unhide them?
Thanks.

@ironic thanks for your help.
My gamepad is working fine but i have a question about how to exit the emulator.
I don't know exactly what i do but now i can exit directly to emulationstation when i hit F12
Maybe a new implementation?
I've changed the default uae4arm bin for the lastest version.
Works with whdload and adf games.
Is there any option to exit ua4arm by hitting a gamepad button or a combination?
I want to play with the gamepad only.

@ironic what type of files are exactly those?
How can i use them?
Thanks.

Finally its working , thank you for your help.
I share my config:

/recalbox/share_init/system/.emulationstation/es_systems.cfg

<command>/recalbox/scripts/emulatorlauncher.sh %ROM% "vectrex"</command>

/recalbox/scripts/emulatorlauncher.sh

if [[ "$emulator" == "vectrex" ]]; then
/recalbox/scripts/runcommand.sh 4 "$retroarchbin -L $retroarchcores/vecx_libretro.so --config /recalbox/share/system/.config/retroarch/config/vecx_libretro.cfg --appendconfig /recalbox/share/overlays/vectrex/$filenameNoExt.cfg "$1""
fi

Well i`ve used my old rpi1 emulationstation config to launch vectrex but is not working

<command>/recalbox/scripts/runcommand.sh 4 "/usr/bin/retroarch -L /usr/lib/libretro/vecx_libretro.so --config /recalbox/share/system/.config/retroarch/config/vecx_libretro.cfg %ROM%"</command>

Is the syntaxis correct or the problem is the "vecx_libretro.cfg" file?
I´ve tried to launch a game from the shell and its not loading the core , but it seams to load the config file
Any suggestion?Thanks for your help

sorry for another replay , could you say me how i do that?

Well ill be waiting for next version. Whats the latest version using emulatorlauncher.sh?

OK , now is working.Thanks.
But i have a new problem.
I saw this awesome tutorial:
https://forum.recalbox.com/topic/1490/vectrex/76

Adding this line on emulatorlauncher.sh
"/recalbox/scripts/runcommand.sh 4 "$retroarchbin -L $retroarchcores/vecx_libretro.so --config /recalbox/configs/retroarch/vectrex.cfg --appendconfig /recalbox/share/overlays/vectrex/$filenameNoExt.cfg "$1""

It`s posible to add a specific overlay for each vectrex game.
How can i do this with the new setup of recalbox?

I want to set-up one diferent overlay per core.
I´ve changed this line on "emulatorlauncher.sh"

if [[ "$emulator" == "atari2600" ]]; then
/recalbox/scripts/runcommand.sh 4 "$retroarchbin -L $retroarchcores/stella_libretro.so --config /recalbox/share/system/.config/retroarch/config/stella_libretro.cfg "$1""
fi

To load my custom settings on the file "stella_libretro.cfg" but retroarch still always loading the default "retroarchcustom.cfg" located at "/recalbox/share/system/configs/retroarch/"

Someone can explain me how to set-up custom specific per-core settings?

Thanks another time , i`ll be waintig for new releases.
It really colud be awsome use a gamepad like on uae4all to play whdload games on our rpi.

Thanks voljega

Well finally its working , thank you so much for your help.
Only one last question , i´m having problems to set up custom keys for playing the games.
Is there any tutorial or anything like that for this?
