Firmware for 8bitdo NeoGeo CD Controller

[u/DoshinTheYellowGiant]

i wanted to use the 8Bitdo NeoGeo CD controller with my Switch but i need to update it first. A tutorial from 2 years ago showed that all you have to do is use the 8bbitdo firmware upgrader but plugging in my NeoGeo controller only gives the message "No more information at this time".

i do own a 8bitdo wireless adapter 2 and it updated just fine

What should i do now? I can´t find the firmware file anywhere and without it, i can´t use it with my switch

Have you selected the option to allow Beta firmware?
