I also have the older revision board, and im very interested in this update. My retrotink 2x is just UNUSABLE with the N64 audio.
Where can i find the FIRMWARE file?
And i have another question, is it possible to add PAL-M (brazilian TV color system, wich is similar to NTSC in resolution and refresh rate) support in the future? I have many PAL-M devices that only outputs black & white when connected to the retrotink 2x.
