I downloaded from archive.org the Sega Saturn CHD US 2020 pack - i cant get any of them to run on the new unstable core - they show up for loading the chd but just get the "drive bay open" problem.
Can someone recommend another pack that has working files?
I don't think that's the problem.
I've got known-valid CHDs that I used to extract CUE/BINs that work...but if I try the original CHD, even with the very latest unstable Saturn binary and unstable Main-MiSTer, I get the same result as you...none of the CHDs will even attempt to boot.
It's not a BIOS issue - the BIOS works perfectly fine with the CUE/BIN version.
for me chd works with last build of core and main MiSTer ... some from archive.org and other make myself
Make sure that you use the latest unstable version of MiSTer Main (dated 20231011 or later) together with the unstable Saturn core.
I only tried one CHD compressed game so far, and that one worked fine. Was a T-ENG patched version of Silhouette Mirage.
edit: Also tried a random game from this archive.org collection (DecAthlete (USA).chd). Works fine too.
Sega - Saturn [Redump] Collection (CHD)
I had to use the unstable main from the 16th, no other unstable worked for me since a couple of weeks. (Just black screen while turning on).
With that one I can enjoy CHD now.
I get “CD bios not found!” when trying my CHD files. I’m just on the latest release (from this morning), nothing unstable. I can see the CHD files in the Saturn core but get this message when I try to launch them. I have another set of CHDs downloaded on my PC, so I’ll try those and see if they work.
EDIT: Oh, I need to add and load my own bios. Not a super advanced maneuver, but I assumed going through "official"/stable channels it would be included. I can see why it wouldn't be, so no complaints.
You need to name your bios boot.rom again. It was boot.bin a while ago, but it was changed back to boot.rom. It is confusing, but those kinds of things are expected with beta WIP core development. CHD works fine for me, using one folder per game, tested with Radiant Silvergun, Bug! And other games. I am still getting CD audio cutting out after a while of playing Sega Rally or Radiant Silvergun. In Bug! (R) release, the cd audio seems fine even after 45 minutes of playing. I think all of that is because it is still a beta core in active development.

Agreed here. Sega Rally seems ok most of the time, but Nights into Dreams music cuts out after a few seconds (which is a shame as the music is awesome). I'm going to hold out a while before I invest in new RAM because as you say, it's still very much beta.
I have 2 chip, v2.4 128mb ram btw.
Hi there
maybe my saturn collection is old so i need to ask about the most common and working files. Currently my games do have four files. 1 txt file with the name of the game. One CCD File one SUB File one CHD file. Is this needed or do just the CHD work as a stand alone CHD file in the game folder
Kind regards
im afraid your path ends here ... Jago
