Reicast missing from Retropie setup (trying to adjust controllers)

[pbc]

Pi Model or other hardware: RPi4 - 4GB
Power Supply used:
RetroPie Version Used (eg 3.6, 3.8.1, 4.1 - do not write latest): 4.6.6
Built From: Pre made SD Image
USB Devices connected: Arcade1Up joysticks, XBox One Controllers
Controller used: Arcade1Up SFII modded cabinet, dual XBox One 2015
File: (File with issue - with FULL path)
Emulator: Several
Attachment of config files: (PLEASE USE PASTEBIN.COM FOR LARGE LOGS)

So I'm using a premade image for my Retropie which has a bunch of emulators on it. One of those is Dreamcast, but I am having issues getting the xbox controllers to work. Using F4 and then trying to adjust the input isn't working.

Saw a video online about how to access controller settings via Retropie setup here:

But I do not seem to have the Reicast option available?

Okay, also found these files which shows my xbox controllers:

/opt/retropie/configs/dreamcast/mappings/evdev_Microsoft X-Box One pad (Firmware 2015).cfg

[emulator]
mapping_name = Microsoft X-Box One pad (Firmware 2015)

@pbc You have either to ask the creator of your image, or do a fresh install of the offical retropie-image.
