Creo que la pregunta más relevante es si actualizaste algo antes de que dejaran de funcionar? Quizás Recalbox te ofreció instalar algún update y lo aceptaste?

Yo tengo mandos de 8bitdo y los míos tienen la opción de usarlos por USB. Si los pruebas por USB el problema persiste?

Ok, I'm going to leave the solution here for anyone who may need it in the future:

https://github.com/libretro/libretro-fceumm/issues/308#issuecomment-560408467

if using the US rom (NES), set User 2 to NONE instead of auto. if using the Japan rom (Famicom), disable User 5 instead.

Further explanation:

on NES, player 2 port acts as expansion port, including arkanoid paddle in this case (using mouse)
on Famicom (when loading Japanese ROMS), expansion port is on a dedicated port which is mapped to User 5 on fceumm.

this should resolve this issue and any other confusion with nes/famicom expansions

Sorry for the double post but the forum won't let me edit my previous message.

I've procured a No-Intro rom set for NES. There where two versions available (headered and unheadered).
The unheadered rom won't launch with any core.
The headered rom launches fine but I get the same results as before.

Is there anyway I can verify I got the proper rom using the checksum or a hash? Like the dat files used for mame rom sets?

Honestly I don't know the origin of these roms, I got them out of a premade image I tested.
Based on your suggestion I found a Japanese arkanoid nes rom and the controls work fine on that one!
The cheat codes included for the US version don't work as probably the memory mapping is all different but that is progress!
So now I will try to get a proper version of the US rom to try or hunt down some cheat codes for the japanese one.
As the people how know keep saying, check your rom set! I didn't thought it was so important for 8 bit consoles but clearly it is.
Thanks for your help!

Thanks for the reply. I just had time to try this today.

Effectively there is an "Arkanoid" option under Controllers for Player 2 but I after connecting two controllers and starting a two player game, I still can't move the paddle with either controller, I tried both user turns.

That's a shame since it seemed a very promising lead.

Hi. I have spent a few hours with this game and I'm very confused about how the emulators handle it.

I want to play using the DPAD because that is how I used to play it in my childhood (on a knock off Famicom compatible system) and I would like the chance to use a cheat code for extra lives so I can finally see the more advanced stages of the game, but I can't find a combination of core/settings that will enable me to do that and I'm very confused.

Here is what I have so far with the latest updates installed this morning (RecalBox 6.1.1) on a Raspberry Pi 3. I also tried updating cheat codes and databases from Retroarch Online Updater menu.

Core Controls Cheats
Quickness ✔️ ❌
FCEUNext ✔️ ❌
FCEUmm ❌ ✔️
Nestopia ❌ ✔️

In the two first cores I can move the paddle but cheat codes don't work. In the last two I can't move the paddle but cheat codes work.

I read that in the US Arkanoid was bundled with a special controller but I figured the emulators would work around this and allow the use of the standard controller (which the first two seem to do).

I have tried every single setting I can think of changing the control to auto/gamepad/gamepad with analog. etc.

If it makes any difference, I'm using an 8bitdo NES30 pro and tried both the dpad and left/right sticks with the same results.

Any help on how to achieve what I'm trying to do would be appreciated.

Update: I also tried plugin in a keyboard and mouse to the Pi. The keyboard works in all other NES games I tried but not in Arkanoid. The mouse doesn't do anything but I haven't try running the setup for the mouse to see if it makes any difference.

Thanks for the quick reply.

So if I understand correctly that means that even if I set the auto-fire option manually in the FBNeo .cfg file it won't do anything in Retroarch?

In that case my best option is trying to get the "turbo" button setting to stick to the ROMs where that feature is useful.

Hi all, thanks in advance for taking time to read this.

I have the Metal Slug games (1 through 5 and X) working on my Raspberry Pi 3 with RecalBox 6.1. I'm using the default core (FBNeo).

I'm able to access Retroarch (Hotkey + B) and set Auto Fire to On under Options but it doesn't change the behavior of any of the buttons in the game. The other options seem to work fine (Free Play, Setting Mode, etc).

I tried a workaround (setting the fire button to Turbo under Settings, Input, User 1 Binds and it works until I exit the game and have to set it again next time. I already tried saving a Game Override but that doesn't seem to have any effect.

Interesting. I was getting a black screen with all the games I tried. I could access the RetroArch menu and try to load a new rom and I will not see any error messages, just a black screen and no sound.

The roms/bios I was using I extracted from an RecalBox 6.0 image released by Warpgate. I like the game selection but I don't like the heavy modding done to the theme.

I ended up deleting the neogeo.zip (1.4Mb) file from roms/neogeo and copied a new one under bios/fbneo

The new one is 1.7Mb and can be found as part of a "RetroArch Full Bios Set" xxxxxxxxxxxxxxxx if anyone needs it.

After doing that I tried about 10 games (including Metal Slug 1 through 5 and X) and they are working great. I can confirm they are launching in FBNeo and was able to access the soft dip menu to enable free play, blood, etc.
