Nice work! I always wanted to give that a try, since the PSX versions of those games look surprisingly good.
I'm extremely fussy about quality when it comes to archiving laserdisc video.
However, I find that when actually playing games in Daphne, the video quality isn't a huge issue. (Most of the time I use very small test MPEGs.) With the cleanup you've done, the PSX discs should be more than sufficient sources for Daphne-compatible footage.
Two things would be needed to make these playable in Daphne:
1) A framefile that gives starting frame numbers for each of the clips from the CD. These can be arbitrary (1000 file1.m2v, 2000 file2.m2v, etc.), since we don't have the original ROMs expecting certain frame numbers. If the conversion/processing tools can be run from a script/batch file, then an "xxx2DAPH" converter would even be possible.
2) A new game driver in the Daphne code. While it is *possible* to hack the ROMs from an existing game (for which Super Don would probably be a good choice), it would probably be better to make a generic game driver in the Daphne code itself. This has been discussed a few times, and doesn't seem prohibitively difficult. It could parse a 'ROM' with a list of scenes, moves, timing, frame numbers, and branches to other scenes. Scoring and 'skinnable' overlay graphics would be nice, too.
This would open up all sorts of opportunities for "fan ROMs" to make games from various sources.
Unfortunately, I'm still trying to fix MACK3, so I won't be working on this any time soon.
Still, if someone takes this on, I'd be glad to help with the design.
