2013.08.29 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. http://mamedev.emulab.it/kale/wp-content/uploads/2013/08/00001.png http://mamedev.emulab.it/kale/wp-content/uploads/2013/08/00011.png http://mamedev.emulab.it/kale/wp-content/uploads/2013/08/00002.png http://mamedev.emulab.it/kale/wp-content/uploads/2013/08/0269.png http://mamedev.emulab.it/kale/wp-content/uploads/2013/08/0013.png 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. --
