DevelopersCorn: Active, has been working on speed, compatibility, bug fixes... the works. =D
Salvy: Active, mainly working on compatibility.
Wally: Semi-Active, works with blendmodes and code clean up.
Kreationz: Inactive, though he still pays for and owns the site. Not sure whether he has plans on returning but from what I know life is busy for him and doesn't have the time to help out.
StrmnNrmn: Inactive, busy with life. StrmnNrmn is the owner of the original Daedalus project. From what Kreationz said a long while ago there was talk of him returning to help out. But as far as I'm aware that did not work out.
Howard0su: Inactive, is busy with life for sure. Along with Chilly Willy and StrmnNrmn had plans on helping out but seems none of that worked out either. Its been a while since then.
Chilly Willy: Inactive, he helped Salvy on the low battery warning a long while ago. There was talk of him also returning as well but to the best of my knowledge he is still too busy or has lost interest.
Grazz: Inactive, due to some unforeseeable issues lost interest, and is also very busy with life. I'm not sure of his plans but at the moment seems he will not be returning.
Zack: Inactive, was active for a bit and took a look at the code and added more VFPU math to it, but then left for other projects. Seems he will not be returning either.
ShinyDude100: Inactive, he added a few blendmodes along with kreationz a while back. Seems to be busy with school and other things. No plans on returning as far as i know.
Yamagushi, Inactive, a while back made a new GUI, which has since been changed. Drops by the IRC every once in a while but as far as I know has no further plans for dx64.
psppwner300: Inactive, he added a couple of GUI things a while ago but has since moved on.
Maxi_Jac: Inactive, added a couple of new features a while ago, the names of which escape me. Seems to have gotten busy or lost interest, not sure, its been a long while and I'm not sure of his plans as he disappeared without saying much.
Hlide: Inactive, was around at the beginning of DX64 but since then has got busy working on other projects.
Azimer: Inactive, but we use his audio code with daedalusx64. Kreationz used to maintain contact with him... From what Kreationz said he plans to continue his original plug-in work for the N64 emu scene in general with plans for it to be open source.
Blendmode Fixersbdacanay: Inactive, was working with Wally on blends a long time ago. Disappeared as he got busier and busier.
DarthSidious666: Inactive, started his own string of daedalusx64 unofficial builds that target one specific game but has since not been seen.
NintendoBoy13: Inactive, me... busy with life and may do some small things now and again. Never did much at all to be perfectly honest. I hang around the IRC and forums. Don't really go by this nick anymore.
Note: z2442, and anyone not in the above list: As far as I know they are inactive/never contributed code to the project.
SummaryCurrently there are 2 developers who are active. They work on things in a private SVN, and make then commit the changes to the public SVN when ready. Its been a while since a rev has been released to the public SVN (as of 7/18/12) but they've still been hard at work. Corn and Salvy both are busy with their own affairs but do find time to work on code.
BTW if you're interested in some of the work of the old devs I'll provide a few links.
Also try taking a look through old daedalusx64 threads for info ^_^
#DaedalusX64 on Freenode has been slow lately but Corn, Salvy, and Wally usually visit at least occasionally.
