maybe some of you know the "Hasbro - Video Now" movie player... it's a portable movie player with a 3" built-in screen. the interesting thing about this player is the video-codec it's using.
Video's could be bought on special cd's (which are smaller than normal cdr's) and the video's are stored as audio-tracks. you can rip them as WAV-files.
a guy already figured out the structure of this video-codec and even provided a filter for using with VirtualDub, so you could convert your own video's into this audiotracks and watch them on the "Video Now" (you have to modify the hardware, so you can put normal cdr's into it)
some informations about the video-structure and even the filter for VirtualDub can be found here:
a video of this system can be found here:http://www.youtube.com/watch?v=0J--JuLkHIc
if anyone is interested in maybe adding this to MESS, i can provide scans of the internal pcb of the player and i have also a couple of original "Video Now"-Discs here..
i know this is not really an emulation-thing, as it's only a movie-player...but it's worth to preserve it...
video-quality is something like those GBA-Video's...
