Guys, I've been following recalbox since version 4 and despite having a RPI 3B+ ( without overclok ) it was utopian for me to be able to play fluidly with the Dreamcast emulator ( Flycast ), today out of curiosity I tried Virtual Striker 2000 and the fluidity I finally found was incredible without having to switch to a RPI 4, so I wanted to say a heartfelt thank you to everyone who made this milestone possible.
Now all work fine was my error, thanks guys !
@Zing Thank You, I'm very happy to have helped to highlight a bug.

Hi guys, I finally noticed that the fantastic https://www.screenscraper.fr is back to work, in fact I can do the Skraper from a PC, but not internally in Recabox 7.0.1, why?
Infinitely thank you for your immense work.
Buongiorno ragazzi, è possibile su Recalbox tramite un comando, disabilitare/abilitare una o più porte usb ?
Grazie
Hello guys, is it possible on Recalbox via a command, to disable/enable one or more USB ports?
Very Thanks.
@johnnybad82 ciao, sinceramente non ho mai riscontrato questi problemi su RPI 3B+ collegato via hdmi tramite un adattatore vga-hdmi ad un monitor vecchio 4:3. Prova a installare in modo pulito tramite il tool di recalbox ufficiale della homepage o a verificare eventuali casse audio/altoparlanti.
aggiungo che puoi usare semplicemente "Gestione Disco" di Windows e puoi eliminare le partizioni e allocare lo spazio.
Hi, you need to read this documentation "https://wiki.recalbox.com/en/tutorials/games/generalities/isos-and-roms/romsets-for-recalbox", the correct romset for Recalbox 9 is "FinalBurn Neo v1.0.0.03", google is your best friend 
Ciao, guarda a mio avviso devi utilizzare uno dei tanti software che permettono di ripartizionare le unità, anche io ho una sd da 200gb e tempo fa usai partition magic, ma ce ne sono diversi, anche gratuiti, basta seguire su youtube le varie guide.

Hello everyone and thanks again for the immense work you do.
I have recently installed RB 8.1.1 ( all bios and romset working perfectly ) on my Arcade Cabinet with RPI 3B+ ( with the next pixel theme ), I wanted to ask you if you recommend a simple update to the new version 9.0 or if a new and fresh installation is better.
Thanks.
Damiano.
@Zing said in Rb 7.2 on rpi 3b+ - PSX emulator gpio problems ?:
@Space81 Ignore this part, you have already configured the joystick in a game, copy that configuration and see about the configuration overload, which was the solution used by the other user:
https://recalbox.gitbook.io/documentation/advanced-user/configuration/configuration-overload
@Zing from documentation link :
"Standalone emulators
We can't currently overload the configuration of standalone emulators except for Amiberry's and Amiga for ARM's, partially.
Adding these overloads isn't on the calendar, since they require code and specific tests. This more or less isn't doable for every emulator, but in any case, this will require a rather substantial amount of work time.
However, depending on the demand and its relevancy, we could eventually work on a per-case basis."
@Zing I tried to execute your guide above, where it specifically says :
"In the retroarch menu (hotkey + b), go to Settings and then Input user 1 keys"
but unfortunately in the case of the Amiga emulator (Amiberry), the hotkey + b command does not refer to the retroarch menu, but to Amiberry itself, so unfortunately in this case it is not possible to configure the input commands except from time to time. 
@Zing thanks for your infinite patience, I'll try again.
