Have you tried saving the shader preset to the core or gaming? Just follow the path: "Quick Menu" > "Shaders" > Select the shader preset you like > "Save Core Preset" or "Save Game Preset" (according to your preference).

See if this helps.

As for NTFS and exFAT, their compatibility is quite different.
NTFS:
Compatibility: Works with all versions of Windows, but read-only with Mac by default, and may be read-only by default with some Linux distributions. Other devices — with the exception of Microsoft’s Xbox One — probably won’t support NTFS.
exFAT:
Compatibility: Works with all versions of Windows and modern versions of Mac OS X, but requires additional software on Linux. More devices support exFAT than support NTFS.
According to the comparison, exFAT seems to be more compatible than NTFS. In different situations, you can convert NTFS to exFAT or convert NTFS to exFAT via Disk Management, Windows File Explorer or DiskPart command line.

I downloaded windows version of oricutron and this doesnt support zipped files. At recalbox i tryed the same roms without compress and finally works!!! Thanks

Connect the controller in switch mode (its name will now be "pro controller"). All the buttons will be recognized.

You'll find the whole procedure here: https://retropie.org.uk/forum/topic/21481/8bitdo-m30-bluetooth-controller-issue

For the layout, I put B, A, R2, as ABC and Y, X, L2 as XYZ (this way, Z, C and the shoulder buttons don't overlap). It works like a charm!

@schattenwesen could you please open an issue reporting this problem here:

@toastman

Use this tool, to check, if Netplay TCP Port (should usually be 55435, if I'm not mistaken) is open:

@marcos hmmm yeah ingame but actually i just rembered that the dreamcast emulator isn't a libretro core so it's just not possible to do what you want at the moment

@tdelios Searching in the forum, I found two situations similar to yours:

In one of them, the problem was in the Theme, and using the default theme or another theme solved the situation In the other situation, setting the joystick on the main menu solved the situation.

@paradadf It ended up that I had uploaded the .rar of my rom instead of the .bin. Once I extracted the .bin, it worked.

My assumption regarding lack of Start / Select button in controller configuration was right.

I solved the problem by simply adding fake entries to /recalbox/share/system/.emulationstation/es_input.cfg

You know... I did everything under the sun to find this out, and it's always something so simple. Much appreciated Acris.

@solo-ripper given you have the right bios, chrck the game isn‘t protected (it doesn‘t need .sbi files along the rom).

@substring It's ok now. As you said, I've redownload the .img file and install it with Etcher and it works.
I think the problem is that when the installation with Etcher is done, Windows ask the user to format SD Card because he can't recognize the new file system. If the user don't take care, he can reformat the SD card.

Thank you for your help ! :)

Thanks guys

I have filezilla, didn't know it could be used with the Rpi.

Also i read here:

that this is also possible for those times when you need to transfer larger files without worrying about files dropping out.
