@darth Hello!
I also had problems with the PSP emulator on RPi3, and I've seen other reports about that, the "solution" I found was:

• If you're using a 1080p theme, you need to change to 720p
• In addition, in the folder "\share\system.emulationstation", in the es_settings.cfg file, find the line "<int name =" MaxVRAM "value =" 200 "/>", and change the value from 200 to 80, getting : <int name = "MaxVRAM" value = "80" />
• Go to the folder \share\system, in the file recalbox.conf, find the line "dreamcast.videomode =" and add just below it the line: "psp.videomode = default" (without quotation marks, obvious)

With this, the PSP emulator is able to work most of the time, and if the game does not enter immediately, just wait a bit, and try again, the game will start.
I know some people do not like this solution, but that's what solved for me.

@richr37 Install a different theme and test, maybe it solve.

¡Hola!
Por favor, no "desenterrar" un tema antiguo, abra su propio tema cuando no hay un tema actual, ya que el problema de meses atrás probablemente no es el mismo problema que usted está teniendo hoy.
Inicia un nuevo tema, especifique qué versión de Recalbox están utilizando, qué arquitectura estas usando (PC32,64 / Rpi0,1,2,3) ... Hacer copia de seguridad y empezar una instalación limpia de la versión más reciente resuelve las veces, ¿Has intentado esto?
¿Ha intentado cambiar el controlador de control?

@jorgemagana ¡Hola!
Yo recomiendo el ARRM, que a pesar de poseer sólo en los idiomas Inglés y Francés, es práctico y muy funcional:

@josklown ¡Hola!
No sé lo que puede estar sucediendo para que no pueda actualizar, pero a veces es más fácil hacer copia de seguridad de la carpeta SHARE, y grabar la nueva versión actualizada en la tarjeta, restaurando sólo el contenido de la carpeta SHARE ...
Es una opción, no sé si eso te ayuda ...

@angardi ¡Hola! Estos botones funcionan en el juego original? He visto una lista de golpes de Tekken 3 y no he visto ningún golpe con estos botones ...

@t-h Hello!
Probably what you need to do is edit recalbox.conf and set the global.videomode to default:
global.videomode = default

@damien-svanberg If I'm not mistaken, Recalbox is conflicting with Noobs, and there's no solution for that, it's not just you.

@morgothsauron If I'm not mistaken, the scrapper is giving trouble lately, then it should be just that.
The next version of Recalbox can improve this, but they were even considering eliminating the Scrapper because of too much trouble with the sites themselves.

I recommend ARRM for the scrapper:

@smilocrypto Hello!
I'm not sure if I could understand your doubts, but from what I understood:

• You do not know how to stop Emulationstation
• You want to use a pendrive to store the ROMS, OR, Do you want to run the Recalbox entirely by a pendrive
• You can not run the PSX games.

Since these are your doubts, what can I try to help you with:

• It is possible to stop Emulationstation directly from the web manager, I'm not sure of the correct path now, but search for a "Stop Emulationstation" option, and there is the option to start or restart as well. Another option is to do this directly on the computer, I do not remember now if you just need to press F4 or CTRl + F4, but it's something like that. When stopping the Emulationstation, the screen will turn black, but the recalbox keeps working, do not get confused.
• It is possible to install the recalbox direct in the HD, like main system, but also it is possible to install to turn totally via Pendrive, as it prefers. But, it is possible, for example, to install the system in the HD, and some ROMS in a pen drive, and make the Recalbox read the ROMS by the pen drive. This option is in the manual, at the link: https://github.com/recalbox/recalbox-os/wiki/Use-an-external-usb-storage-device-on-recalbox-(EN) (the first part of tutorial is optional, as you can see)
• Only these extensions are accepted: ".iso / .img / .bin / .pbp", in addition, you need to have the BIOS properly inserted in the BIOS folder. If none of this is a problem, you can try changing the emulator / emulation core to test. And there is the possibility that the problem being your notebook does not meet the minimum requirements for the emulator to work.

But other options for moving the ROMS to Recalbox are:
Use WINSCP (https://github.com/recalbox/recalbox-os/wiki/Network-access-with-WinSCP-(EN))
I think in the PC version it is possible to access a kind of file explorer by pressing F1 (I'm not sure, I use the RPi version, but I've seen it in a video)
If you are trying for the cell phone, another option is to use the program Es file Explorer on android, open the app and go to Network, Search, and you should find the recalbox and be able to transfer the roms bigger than 256mb.
