    [quote=118409]Well it seems the video file I was using is prolly not good.
    How would one generate one from the DVD? I’m guessing the .bf files aren’t useable.
    Any word on which DVDs are supported?
    Does it have to be an .m2v file?

    And last but not least:

    what does the lair.txt (or dle21.txt) do exactly? Is it a sort of video frame skipper to tell it where to begin with its playback?

    Wow that’s a lot of questions :p

    Yeah, the frame file just lists the ‘start’ frame for each one of the video files.
    The DVD rip I have has each scene as its own m2v file, but I know there’s other rips where there’s one file for the entire disc.

    Daphne uses libmpeg2, but there’s no reason it couldn’t be modded to support other video formats and different libraries (or the pi’s hardware video decoders perferably).

    The GPL’ed source tarball for daphne is *really* old software and a lot of it’s poorly written, so it’d probably benefit from a rewrite (and using more robust microprocessor emulators that the ones written specifically for Daphne), but who’s got that kind of time ;)

    I haven’t pulled the new retropie package, since I compiled from source a couple weeks back, but if anyone’s interested, I’ve added support to drive an external LED scoreboard over USB.

    Windows daphne builds control the scoreboard over the parallel port (and I started making repro scoreboards with DB25s for daphne about 15 years ago), but since newer PCs generally lack parallel ports, I developed a little USB dongle to interface to both original and repro scoreboards.

    The only added dependency is libftdi1, which compiles cleanly on the pi.

    Since there’s no ‘official’ source repository anymore, it’d be good to get my new code into the retropi git at least :)

    I’ll drop a video on youtube.

    Daphne / Pi with USB scoreboard

    It’d be nice to do a build that uses the Pi’s hardware mpeg decoder instead of libmpeg as well.
