Some games like Time Crisis, Point blank, requires A or B button to play or to skip calibration screen.
If I go to Main Menu > Settings > Input > Port 1 Controls , I can set it (they all show like N/A but still working). But they wont save, I tried all possible saves in Retroarch (save on exit, save core settings, save input core....) none seems to work.
Is there anyway to save or I have to config each time I want to play?
I´m back testing light gun games like 4 years later, and I still have same issue that I explained in this thread:
https://forum.recalbox.com/topic/24916/psx-light-gun-games-not-working
I´m on Raspberry 5, 9.2.3-Pulstar. Most MAME (not all) and all PSX lightgun games wont start if Wiimote is mode 2 with dolphin bar plugged. To start the game, and have to unplug bar or change wiimote mode, and then back to mode 2 to play, wich is very tedious. Rest of systems work fine in mode 2.
I though this bug after so many versions was solved but no... So I make a new thread to see if someone can point it for further version or there is any solution on this current.
Im using Raspberry PI 3B+
The last release is going very slow for me in Neogeo games and many FBNeo as they use the same core.
In other versions of Recalbox, setting "CPU clock" over 100%, like 300%, fixed slowdowns in all games, like Metal Slug. On this version, going over 100% of CPU clock make the games even slower and really bad performance.
I have a 9.0 Pulstar image that don´t have this problem with same roms and BIOS, also in Raspberry 3 B+.
I assume is some kind of bug in this update? Any tip to solve it?
@zing Yes, I read it. But some people say is a problem in RPI3 or RPI3+, for me is RP4
Also some say that some games are working fine, for me is totally impossible play any PSX game.
I saw some videos playing Time Crisis in PSX for 7.2, but in 7.2.2 is impossible. Older versions work better for PSX light gun?
@moyo_ml Tried a fresh install and still not working. Is a problem in 7.2.2? Ive seen videos of 7.2 playing PSX light gun very well
Hi. I'm unable to start PSX light gun games when Dolphin bar is connected in mode 2. It returns to game list.
Only occurs with lightgun games, the rest of PSX games work well. Also when Dolphin bar is unplug, the light gun games load and work well (but with joystick).
I'm on RP4 8GB with 7.2.2-Reloaded.
Tried to restore Factory Settings, still not working.
Tried with RP4 4GB, not working.
Tried games .BIN and .ISO, not working both.
Other modes in dolphin bar dont work.
I don't know what is wrong, please help 
I don't have one, anyway I don't know how or where to use it, or if I find something unusual I won't know why it happens...

@voljega said in LEd Buttons pressed by themselves with Xin Mo 2 players interface:
Try without the led and see from there
Hi. As I said, without the led power eveything works perfect, so I ask what or where or why this is happens...
The problem is that buttons are pressed randomly themselves when I'm in Recalbox If I have the LEDs on. The menu is moved along without touching joysticks, Start is pressed without touching, it enters games without touching anything .... If I disconnect the LED lights, the buttons work perfectly.
Sometimes, it seems that the buttons are correctly (they are not being pressed by themselves, or not much), but if I press a button repeatedly and quickly (for example, the A button in the menu, which does not change anything), it affects other buttons like the B button or the Start button that are pressed without touching them. I've also tried this with LEDs unplugged and it never happens.
The LEDs are powered by an external charger, I have tested with 5v and 12v, and it happens in both cases.
I use USB interface Xin mo 2 players, I have tried both 18 pins and 20 pins, it happens in both cases.
The truth is that I do not know what I'm doing wrong, I guess it's the electric current of the LEDs is affecting the buttons to be pressed by themselves, but they are not in contact anywhere with grounds and signal wires of the microswitch buttons, all It is isolated with its covers.
Right now I have the problem in Recalbox 4.1, but in previous versions it also happened to me.
I do not know if interfaces are defective , or if I have to wire something different ....
Thank you and sorry for my english..
El problema es que se me pulsan botones solos cuando estoy en Recalbox cuando tengo los botones LEDs encendidos. Se mueve el menú solo, se pulsa Start solo, entra en juegos sin tocar nada.... Si desconecto las luces LED, los botones funcionan perfecto.
En ocasiones, parece que los botones están correctamente (no se están pulsando solos, o muy de vez en cuando) , pero si pulso un botón repetidamente y rápidamente (por ejemplo el botón A en el menú, que no cambia nada), afecta a que otros botones se pulsen solos, como el botón B o el Start. Esto también lo he probado con los LEDs desenchufados y nunca ocurre.
Los LEDs están alimentados con un cargador externo, he probado con 5v y 12v, y ocurre en ambos casos.
Utilizo interfaz USB Xin mo 2 players, he probado tanto de 18 pines como de 20 pines, ocurre en ambos casos.
La verdad es que no se que hago mal, imagino que es la corriente de los LED la que está afectando en los botones a que se pulsen solos, pero no están en contacto en ningún sitio con las masas y las fases de los botones, todo está aislado con sus fundas.
Ahora mismo tengo el problema en Recalbox 4.1, pero en versiones anteriores también me ocurría.
No se si es problema de los interfaces que están defectuosos y les afecta el voltaje de los LEDs, o si tengo que cablear algo diferente....
Gracias.
