I have a good many original games for Saturn and Playstation 1/2. Does chdman support ripping these directly to chd?

no. you have to use some other tool to rip the discs into bin+cue, and then chdman to pass to chd.

... and then you don't stand a great chance of exporting them back to identical bin/cue from CHD, for that matter. However, if one-way conversion to CHD is fine, then yes.

it depends. if there are no pregap offsets, you can basically go back to the original bins (cue can be fixed by hand) by possibly splitting the big .bin file output by chdman into per-track .bins (i've done it with multiple redump.org rips)
but yeah, given that the bin+cue format consists of a dozen of different variants it's quite hard to handle generically the conversion in both directions

I have been thinking about adding direct ripping though, since I've been having to learn about the T10 commands used by SCSI and ATAPI.

that would be great! especially if it could be made working without too much pregap-postgap voodoo recipes

That's overstating the problem; the resulting exported bin/cue should burn an identical disc and/or work fine in Daemon Tools or Virtual Clone Drive. It's only if you demand exactly the same files in the same configuration that things go wrong because bin/cue is more of a guideline than a rule.

It would possibly be worthwhile duplicating the EAC voodoo in something that can rip an entire disc as one file.
Although I think we'll probably end up with golden drives.

That would be great!

Did chdman ever gain the ability to rip directly? If not, what is the preferred method for dumping psx/Saturn games these days?

AFAIK, just HDDs, not CDs.

Until the CD dumping scene can finally agree on one holy ripping program/format, which may never happen, I think we're still going with (on Windows):
1. Burnatonce - http://www.majorgeeks.com/files/details/burnatonce.html
2. 'Settings' -> 'Device Settings' -> 'Read Settings', ensure 'Read Raw' and 'Raw RW Subs' are selected/checked.
3. 'Read/Copy', then select 'Read To Image'
4. chdman createcd -i image.toc -o image.chd
should work fine.

Thanks for the instructions
I was going to use imgburn, but this will work to. Is there a verification procedure? Rip twice, compare hashes, etc?
I don't have a huge library, but can I submit any rips I do for inclusion in MAME?

We generally prefer that people source CD images from major projects like TOSEC or NoIntro or whatever, as self-rips typically are not reproducible. (For instance, the large chunk of FM-Towns games being softlisted are from the Neo Kobe dumping group).

I gotcha. Shame its seems so difficult in 2016 to easily get consistent results ripping this stuff. CD/DVD drives probably produce different results, depending on brand.

Not just brand. Rip the same disc 10x and you'll find bit-level differences on those 10 rips. Optical read reliability for archival purposes is a terrible scenario for us, and honestly may never get much better as the drives just keep getting cheaper.

For you PlayStation discs you might try and talk to the Redump crew or consult their Dumping wiki especially since the majority of what's getting added to psx.xml is Redump based initially.
I can't remember off hand if Redump and Darkwater method for dumping Saturn discs is identical.

Yeah, even Plextor's given up on fighting the race-to-the-bottom with ever-cheaper hardware. And Apple, who are otherwise quite good at avoiding that scenario, have already abandoned optical media.
