Hi Tom,
1) Machines like those can't be emulated because no emulator exists for the technology they use [in the public domain]. If such an emulator is made public, which I doubt for a good few years, then fine....but I don't think the coders would be that interested.
2) Theres not really any other sites I can think of with all the layouts and ROMs on, if you check the Links section [which is in the right hand frame towards the bottom], theres plenty of stuff in there I think
3) If you can't get into a chatroom, you probably have a popup blocker on. You'll need to turn it off to enter. You'll have to refer to the help section of the blocker to find out how to get around it - although depending on the blocker you may find that holding Control [CTRL] or Shift before clicking on a chatroom lets you in
