So, I got the Raphnet SNES to NES adapter, 8BitDo SN30 2.4ghz controller, and NT Mini Noir (JB6.6).
The L & R buttons don't work to change difficulty settings on the Atari 2600 core. I have to manually set it once entering the core & the setting defaults back to nothing checked once I leave the core, which somehow creates super difficulty in some games. No clue how that works.
Can anyone confirm the 2.4ghz SNES controller L and R buttons don't work?
