i'm using both ps3 clone controller GASIA and kerboard.
As i said before, already tried setting video mode, but no lucky.

@paradadf
Formated the SD card, did a clean install. No fancy stuff in installation.

Now i think i recognised the pattern:
The roms works for one time, and them stop working (black screen forever). For every core the same thing. The game works fine for the first "boot" and them stops working.
I'm using a regular microsoft keyboard, and using "esc" to leave the game.
If i restart the system, the roms work again for the first time, and them black screen forever.

SD card is a Samsung EVO + 32GB.
Raspiberry 3

Ok, I'm going crazy...

Installed a bulk of roms (SNES, N64, PSX, MAME, and SEGA MEGA CD), and now no roms works anymore!

What am I doing wrong!?

Still runing 4.0.1

Funny!
Thanks @Substring !!

Found a similar thread through the thread's tags (wich i was not awear untill now):
https://forum.recalbox.com/topic/4095/all-games-wont-start-up

global.videomode=default

Mine was = HDMI 4 or something
Changed and now every thing works!

Thank everybody for the help!!!

Hi @Substring !

@lackyluuk, I did the recovery mode, and installed the 4.0.1 version, and uploaded to 4.0.2.
No rom (running only stock) worked. All roms went to black screen (with recalbox logo on the bottom) for a few moments and back.

Did the recovery mode again, installed 4.0.1 version, and now some systems work, as follows:
(running only default roms)

• SNES works - Donkey Kong Classic
• None of the NES rom works
• Game Boy Advanced - all roms works at the first run, but them gets stuck in black screen. works fine again for one time after system reset (via run jumper).
• Sega MasterSystem - same thing as Game Boy Advanced
• PCEngine - same thing as Game boy Advanced
• Doom works fine

Does it have anything to do with the way i'm quiting the system?
I'm quiting via HOTKEY + START

@lackyluuk, what do you mean by "videomode to your monitors preferred mode"? the Game ratio (e.g 4:3)?

will try installing BIOS now.

I will update now, and see if i have the bios!
Thanks for all the help!

@lackyluuk

Yes, all extensions are as mentioned in the "readme" file in each rom folders.

I did a reboot and installed 4.0.1 version again.
Default roms were working.
Installed all roms back again, and now none of them works.

Hi!

Thanks in advance!

I'm new to all this... have a raspberry pi 3, with recalbox 4.0.2

I downloaded the OS from the recalbox site link to github, and it was working.
Them i connected to the wifi to install some roms and was asked to upgrade.
So i did.

Now, after the upgrade completed, no rom is working.
They all seem to start but come back to emustation screen/menu right back again.

I'm trying SNES, N64, PSX, MAME... none of them in any rom works...

Am i missing some configuration?

Searched everywhere, but did not find any answer.
