Firmware 0.78 for the OSSC Pro has been released, and although I have mostly focused on downscaling, all OSSC Pro users will benefit from improved Scaler Mode frame locking and some other UI improvements. Here is the full Firmware 0.78 changelog:
* 1920×1440@60 input support added for both analog and digital sources
* 1152x864_75 sampling preset added
* 2048×1536 and 2560×1920 (PR2x) output presets added
* LG VRR compatibility fixed
* Workaround for Mister SNES core jitter added
* Scaler framelocking consistency improved
* Support for RF added (legacy AV expansion)

Features from the previous and current firmware strengthens the OSSC Pro’s (down)scaling capabilities. Firmware 0.77 brought new line multiplier modes, so that a 720p input can drop to 480i or 240p, and 1080p can also decimate to 240p (216 active lines for a 60Hz input to keep it a 5x integer). These new features come at no perceivable cost in lag, at less than 3ms of latency!
Scaler Mode gives much more freedom of image resizing and aspect ration control. However, Scaler Mode Latency in earlier firmware versions was variable depending on the input to output resolution combination, sometimes reaching over 2 frames. Creator Marqs has now reduced this down to approximately 20msec across all resolution scenarios.
Firmware 0.78 also adds support for RF input when using the Legacy AV Input Addon, so unmodified consoles such as the Atari 2600 or Sega Master II can be upscaled and converted to digital. Early adopters of this addon, as well as the Extra AV Out board for analog video can either purchase a 3D printed shell or download the STL files to print themselves.
