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:
https://github.com/recalbox/recalbox-os/wiki/Network-access-with-WinSCP-(EN)

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

I also tested it out with a random megadrive game to use it zipped and that also did the trick.

@harling that's kernel-level side (device ou bluetooth), we can't correct that.

=( i need to wait zero delay in this case.

Thank you so much !

You never should hve chosen your pi version ... This is supposed to be autodetected

@subvers no hadoken possible ? Which version number is your last recalbox ? 4.0.2 or 4.1 ?
