Firmware version 0.72 has been released:
* fix GBI presets
* store size/position adjustments for HDMI inputs as well
* add 2880x2160_60 preset option
* enable 2880×2160 mode for 240p/288p A-LM
* support direct video “DV1” mode from Mister and PixelFX products
* sync processing fixes for Taito F3 etc.
UPDATE: followed up by 0.73 which fixes profile loading issue.
It’s also worth noting that 1080p120 preset (moved under output menu) now has CEA timing option without PR2x, possibly making it more compatible with displays not supporting CVT-RB timings.
