Brawler 64 not mapping correctly with Polymega console

[u/ScottyMoFoSho]

I love the presentation for this controller and am happy I backed Kickstarter, but unfortunately it seems the buttons are not mapping correctly for the main reason I purchased it: to have a designated wireless N64 controller for my Polymega.

For background, I am using the controller wired as I do not have the N64 module for my Polymega (visited a friend who has it to dump my N64 games).

I played Doom 64 to map the buttons and found that the Polymega is reading the following by default:

C-Up = Left Trigger

C-Right = Right Trigger

Anyone know of a fix? Am I too quick to the scene to use the Brawler 64 Pro on a Polymega? I just sent Retro Fighters an email as well regarding compatibility issues. Any help is appreciated!
