The 4000 graphics have been available for some time now, not to mention the emulator. I take it TWC's policy is to just conveniently look the other way regarding such an old system?
Actually the 4000 unit has its graphics on system boards that are probably older than some of the members on this site! It would be essentially like trying to take graphics off a calculator with todays computers

The graphics released out there now are fan made and not originally from the system itself.
You will not be able to get your hands on them unless you are a veteran who is well-known to the administration. Sorry.
No, not at all. These graphics are copyrighted and no exceptions can be made, even if you are well-known to the administration. I may be wrong, but I will have to wait for Martin to give his final word.
Correct. No copyrighted content will be distributed on this site. There are plenty of fan made variations floating around. If you need graphics for personal use I suggest kindly contacting the author of the works. I am sure if you ask kindly they will work with you to allow its use.
