I've done my fair share of trying to get vintage animation via Winny some 10-12 years ago. At one time a Galaxy Express 999 uploader just disappeared. Later on there were reports of his trial, sentenced to jail for uploading videos of cartoons that aired between 1978-81. That is, 25 years ago at the time of the events.
Also see Nintendo's case against M2 and R3 card manufacturers that are now basically illegal in the country. You could be stopped by police on the street and retained if they saw you with a Nintendo DS and a non-standard game cartridge.
