I don't think it is just you.
There is only so much retro-emulation to go around. That and the fact that there were many crap games made on those older systems. These systems might be too difficult to debug for proper emulation, let alone have enough games/ROMS worth playing.
For example,,... how many good games would you say the cd-i, 3do, pippin or gizmondo had?? Even the Jaguar had limited good games.
I don't know maybe they would be worth emulating for the sake of being able too. Unless it has been done already and i am not aware
