Would this be a feasible thing to add? I keep seeing dumps added with the Internal Serial added as a comment, and it occurred to me that literally every PS2 game in existence has an internal serial number (that may not always match up with the serial number on the box!), and so why add it in the comments if it's global across every game on the system? I think it's good information, but I actually never think to do it myself; it's just not part of my submission habit. If the field were there, though, then I as well as other people would certainly notice it.
So yeah, can we add that field for PS2 games?
