Hi, thanks for reply.
The game you are linking to is Fishermans's Bait 1, this game works great on my retropie setup.
But i guess you have a good hint there.
I am sure there is a way to map the buttons for Fisherman's Bait 2 also.

https://github.com/RetroPie/RetroPie-Setup/wiki/RetroArch-Configuration That should explain how the mapping works

Thanks again.

Make sure the roms have the correct file extensions The hub could defenitely be a reason for this.
You could try a hub with a own power supply...

@meleu thanks friend but dont work, i try to create manually in winscp the file emulators.cfg and configurated and works but need to edit manually the file outside , if i try to modify in runcomand inside raspberry dont work and show errors again.

@cybermrc you probably figured this out by now, but the cocktail switch only serves to flip player 2 upside-down. It won't induce the initial rotation.

@felleg I've just read your method to configure the controller for a specific console and I think it's not a good approach. Your configs/megadrive/retroarch.cfg is ignoring the global configs/all/retroarch.cfg.

My suggestion is:

recover the default configs/megadrive/retroarch.cfg (check if you have a retroarch.cfg.rp-dist on the same directory, that's the default config). configure your Hori controller in emulationstation like a SNES controller (square = Y; triangle = X, circle = A, etc.) You need to define if you want to use your Hori controller for player1 or 2, and make sure you'll always use it as that player (if you change, you need to remap). And then use the Core Input Remapping when running a megadrive game and use the following scheme: MegaDrive = RetroPad B = A A = B C = R2 Y = X X = Y Z = R after remap, select Save Core Remap File.
