Topic: How to add additional Button Combo for Hotkey

[rashed4004]

Hello

I want to add a new Button Combo - B+C to use as Hotkey but can not find anywhere to do it.

Can you please help me with it?

Thanks

Windows FBNeo: no problem
Libretro FBneo: Can't (for a stupid reason, retroarch won't allow more inputs)

best regards,

It's for Steam Deck. So, thats not gonna happen.

Thanks for replying anyways.

Exactly, retroarch doesn't allow to declare a button and map it later, meaning you are limited by the number of buttons readily available on their retropad model. See https://github.com/libretro/RetroArch/issues/11273.

The combos made available for neogeo were decided in https://github.com/libretro/FBNeo/issues/51.

thanks guys. appreciate it.

its sad to see their unwillingness to add more key combinations.

You don't understand, this is an open-source project, anyone who cares for a feature is free to implement it.

ahh ok. i misunderstood then.

i saw on those threads there was a particular person that implementing the 4 key combinations we have at the moment and denied to add any more. hence, i assumed he had control over that system.

anyways.

That "particular person" is me, and i'm not "unwilling", i can't for the reasons explained multiple times in this topic and in those github issues.

i am sorry, didnt mean to be rude. just wanted to state what i gathered from reading the threads.

is there any easy way for users to replace any of those button combinations with something different?

Thanks

A C/C++ developer should have no issue building his own core after replacing the macro code at https://github.com/libretro/FBNeo/blob/868dee240104ed2ba3b74ec0bc3c9f467fb284f8/src/burner/libretro/retro_input.cpp#L200-L259 and  https://github.com/libretro/FBNeo/blob/868dee240104ed2ba3b74ec0bc3c9f467fb284f8/src/burner/libretro/retro_input.cpp#L1812-L1821

thank you very much.

Could you please tell me exactly what to re-compile for neogeo core after i make the changes in the macros in 2 below

Sorry, I havent done these before but looking at the button config it certainly looks like i can give it a go and see what happens.

appreciate your guidance on this.

Instructions to build the libretro core are available from https://github.com/libretro/FBNeo/tree/master/src/burner/libretro#how-to-build (obviously you need a dev environment like msys2)

[dink]

Maybe it would be better to officially change one of the combinations to b+c?  Is there one already configured that isn't very useful for most games?

[rashed4004]

BCD isnt that much useful. At least the NeoGeo games that I play like The King of Fighters and some more has no function for BCD

[barbudreadmon]

Users asked for those 4 macros, i won't remove any of them.
