I haven't been able to get a response yet from Skyworth on the upgrade CD.
But I'm continuing to learn how the firmware works on my own. The problem is that I don't have a convenient way to test changes since I don't have a ROM emulator or reprogrammable EPROMs that are compatible with the Skyworth.
So far, the only fixes in my modified firmware are to disable the cross color suppression and correct the chroma delay issue on the progressive component output.
The EEPROMs in the Skyworth are socketed, so it's easy to swap them out. It's just expensive to experiment with one-time-programmable parts. Even burning upgrade CD-Rs would be cheaper than the $10 a pop for two 27c020 EPROMs.
If anyone in Hong Kong would like to help us try and obtain a firmware update CD from Skyworth (for any model player, not necessarily for the 1050p), that would be terrific. Maybe someone has dealer connections or is willing to contact Skyworth by phone...
