May be keep the license hidden and the others indirectly, but you have reason to don t put the x attribute on the table because flags are not use anymore as same.
Only the content matter for the system (sorry i said Value previously, wrong vocabulary)

X3 attribut: 22 00 60 03 (22 just for having export but not necessary) can be probably reduce as 00 00 20 03 (not proper X3 because real X3 will be 20 00 60 03 but ps3 will still like it as X3)
X4: 20 00 60 04
X5: 20 00 60 05
X6: 20 00 60 06

(For others readers in case, to see more clearly the little trick, give me a lot of trouble before getting it even it was plain text)
00 00 20 00 is the X maker and 00 00 40 00 is used as real flag (boot logo disable but i wasn t able to verify, its and better to have this flag because of the type of the game i suppose)
I ll try to have real NEOGEO or PCEngine files ( like the ones from Samson links but not yet fully tested) working to check this.
----------
the little i was able to find are directly connected from Sandungas work (and others from this thread or not), it s really important because he mades something really unique on that file and thanks to him it s really easy to find (and show there a re still a lot to do and everyone can try even someone with half brain as me) or understand it
