So with many arguments for and against I went with briefcase.
Arrived today but only 5 minutes before I went to work so I haven't had a chance to test it out.
Its not very yellowed either and the lid is still intact.
Ys 4 got delivered today and in it was the original disc and a cdr. Maybe the previous owner already ripped and patched the iso..ill find out tomorrow .
Oh and how tiny is it!
