What Changed
Markus has released OSSC Pro firmware v0.82, and the headline change is finalized Lumacode support. For NES users, that should help color palettes behave more like they do on the original OSSC, which is a welcome step for anyone who cares about getting the look of older systems just right.
The update also adds support for an upcoming version of the Extra AV-Out adapter. This new adapter revision includes Composite and S-Video output, giving OSSC Pro owners more flexibility when sending modern-scaled or downscaled signals back into classic video gear.

The Composite and S-Video side is especially interesting for downscaling power users. The setup appears to allow all outputs to be used at the same time, including VGA output through RGBs, which could make the OSSC Pro a very handy hub for people working with several display paths at once.
From Z-retro’s view, this is a practical update rather than a flashy one. Lumacode polish, NES palette behavior, and broader AV-out options all point in the same useful direction: making the OSSC Pro more adaptable for careful retro video setups.
