@OyyoDams It works 100%, now I have a clean instalation of 4.1, even a problem with black borders on my tv is now solved. Many thanks!

Thanks!

Well, this is it...
Untill now I just had to activate the line ;system.power.switch=PIN356ONOFFRESET # in recalbox.conf, but now it doesn't working... I've noticed there is a recalbox.conf-pre.8.0-Elctron file with same command line, but it doesn't working too...
Any help?

Ressurecting the post: I had tried two games in 3DO (The Horde and Road Rash) and none of them works well, so much stuttering... I'm using Pi 3 +.

@airdream Hmmm... Thanks, I think i understood... I really would like to play Ocarina of Time again... : /

@airdream All the other emulators runs fine and I can change from 16:9 to 4:3 at any moment... It only happens with N64 emulator... Thanks for your answer!

Hi, friends! Thanks in advance for all the good work! Recalbox is just amazing!
I'm with a problem in Nintendo 64 emulation (Recalbox 7.1.1 running on rapsberry pi 3 +), the games are always on full screen (16:9).
I would like to put settings on 3:4 with overlay, but I could not change the settings (overlay already installed, I just want to know how to put the resolution in 3:4, to fit the overlay).
Thanks!

I've just made a fresh install of Recalbox 7.0.1 Reloaded, amazing improvment, but I've notice some Mega Drive sound issues. In Strets of Rage 1, for example, when we break the telephone cabins the sound is not right at all (I can't describe it).
I tried turning on Audio Filter and change Sound Quality, but no succes.
Others games has sound issues to, but in SOR 1 we can notice them more easily.
Any suggestions?

EDIT: Changed the core to GenesisplusGX, no more audio issues... But it would be great to know hou to solve the problem in Picodrive core.

F O R G E T I T!!!
It was an error in my paste of roms. It was part of a image I've downloaded and it was some way corrupted.
Sorry and please delete this post. ^^

@paradadf What I want to say is that all my roms in the fba paste does not works anymore after Recalbox 4.1. The roms at fba_libreto paste works fine.
Now I have some 0.2.97.42 roms, and I will try to replace them at fba paste, will this works?

Hello, community! I've just discovered that all my FBA roms does not work with the recalbox 4.1. I found I need to update them with clrmamepro, but I found only a french tutorial about it, can anyone direct me for a english or spanish tutorial? And I must update to which set? Thanks in advance. BTW: Mame and FBA Libretto still works fine, why to change rom set for FBA?
