Yesterday I’ve added a preliminary YUV420 converter to PowerVR2, this fixes FMV movie playback in several games for both Sega Naomi and Sega Dreamcast systems.
It still hangs badly on some games (examples: Naomi Death Crimson OX, DC Tetris 4D), guess that the FIFO needs to be timer-ized in some way.
Fixed after two days of fierce coding/studying the code that prevented GD-ROMs to boot on Sega Dreamcast console. As usual with Sega, status flags are pretty picky on BIOS program …
Compatibility is pretty dire, as you might expect from a complex major system that has zero testing so far. No sound, inputs are mostly not working and several SCSI commands aren’t supported, but hey.
