personally, nemu is worth keeping in hopes of an 0.8 release eventually, even though it would cause you to re-do the whole section obviously.
corn could go, i think emu64 already has all the files and such if anyone would even want them.
ultrahle could probably go as well - again, emu64 has most of the files archived
although.. emu64 still has links to your support pages. even if you wish not to link to them on your front page, keeping the files there for recourse purposes would be nice
p.s., did you ever recover the trwin section?
daedalus is very worth keeping, strmn is still very active in the project.
trwin.. could go i guess, it never had much community support due to the .dat insteaed of ini format.
tr64 is still very worth keeping, if anyone (or anybody) ever got together to give it a good INI
