iBuffalo NES Jump button issues

[Scif1]

Hi everyone. I'm wondering if it is possible to change the mapping per emulator? I have a GRS image that a friend sent that had all the emulators and roms ready for a Pi3. The only issue so far I haven't been able to fix is I can not get Nintendo games to jump correctly with this controller. I have to use the "Left" shoulder button to jump... the b button just turbo jumps and you cant get over the pipes in mario,etc. I've even swapped those in ES setup and they work in the menu reversed but soon as I launch a NES game its the same config as before. I've tried editing the retroarch config the opt/retropie/config/nes folder but maybe I didn't edit the correct values. I would like to swap the L shoulder to B and B to L shoulder in only for the NES emulator as the L shoulder seems to jump short or long as intended for "B". The rest of the time the controller is fine in MAME, Sega, Daphne, etc.

Pi3 B
Canakit Ac supply
Retropie 4.1.5
This happens on both controllers. Used separately even on tested on another retropie and this happens on them as well.

Interesting enough. I deleted both configs /opt/retropie/configs/all/retroarch.cfg & /opt/retropie/configs/nes/retroarch.cfg rebooted and reconfigured USB again and went straight to NES game and its working now. It was a last ditch effort and I noticed both had backup configs as well.
