Ok, I'll give it a try.

Thanks

Dear all, after a few attempts, I finally able to change the config file with my own custom setting.

Now I have a new issue, I have successfully added my emulator specified .cfg and got it running...

ISSUE - 1:

6 play buttons layout to cater Capcom fighting games, which I run in FBA:

fbalibretro.configfile=/recalbox/share/system/.config/retroarch/config/fba_custom_libretro.cfg

I would like to have a different key config for my Neo Geo emulator, a classic Neo Geo layout A, B, C, D.

I have created another custom config for Neo Geo emulator for its 4 play buttons setup (A = Y, B= X, C = L, D = B), and successfully placed and loaded in recalbox.conf:

neogeo.configfile=/recalbox/share/system/.config/retroarch/config/neogeocustom.cfg

To SUM up I have something like this in recalbox.conf:

If you do not want recalboxOS to generate the configuration for the emulator :

fbalibretro.configfile=/recalbox/share/system/.config/retroarch/config/fba_custom_libretro.cfg
neogeo.configfile=/recalbox/share/system/.config/retroarch/config/neogeocustom.cfg

However when I fire up the Neo Geo emu, the play buttons config is same as 'fba_custom_libretro.cfg', in 6 buttons setup, NOT the 4 buttons setup from my 'neogeocustom.cfg'. Strangely under the in-game Retroarch menu (Hotkey + B), 'neogeocustom.cfg' is loaded up correctly; if I change it to 4 buttons setup againt and save "current cfg", it causes FBA emu buttons setup change to this 4 buttons setup too.

Are both FBA and Neo Geo emu sharing the same config in some way? I wish to have this both have their own buttons layout.

ISSUE - 2:

"Error saving remap file"

Due to the issue above, I tried to access the 'Quick' menu under the in-game retroarch menu (Hotkey + B) to change the config here. Unfortunately I can't SAVE the remaps through both 'Save core remap' and 'Save game remap'. I already have the 'Use per-game core option" and 'Save on exit' turn ON.

Please Advice, thanks and cheers!

Thanks for the reply, I will give it a try and see how it goes.

Thank you very much ;D

Dear all,
I need some guidance on how to do the following:
I have already configured a new hotkey setting by pressing Hotkey + B during a game, saved a NEW config (say sample.cfg). Got to "root access" using SSH, successfully rename the sample.cfg to custom.cfg. I want this config apply to all or global and all these steps done according to the wiki guideline.

The next step, I access the recalbox.conf is through network using browser with my Pi3/Recalbox IP, and get to Configuration open up the recalbox.conf.

I'm kinda confused on the next step stated in the Wike Guide:
6) add the next line to recalbox.conf : neogeo.configfile=/recalbox/share/system/configs/retroarch/inputs/neogeo_custom.cfg

If I want my newly created config file (/recalbox/share/system/configs/retroarch/inputs/custom.cfg) to apply to all or global, which "LINE" in the recalbox.conf should I place into? Is this the correct description:

;global.configfile=/recalbox/share/system/configs/retroarch/inputs/neogeo_custom.cfg

Please help. Big thanks and cheers~
