This X0 & X4 CATEGORY's look really interesting, even more when you say there are related with HG... and even more when there is no LICENSE
All this makes me think in a old theory i refused time ago (subfolders inside "game" column ) but well... without an example, tests or reverse engineering from system side is only speculation and i have not much to say, but is a good find, dont erase them from the wiki

The "PSP Export" flag in ATTRIBUTE i think is related to multimedia formats (audio, video & music)
Most of the flags for "speciall content features" has a direct function in XMB (e.g. by pressing triangle over the icon the system offers you speciall options, like game purchase, etc...)
This flag can be tested with the "fake blu-ray structures" i uploaded the other day (in the SFO's that controlls the videos.MP4)

I have few things to update in the wiki, i probably will do today (before this i need to test 1 new flag)
Most of the new stuff is related to a "digital terrestrial TV decoder" only distributed in japan that comes with a speciall disc with a program called "torne", heheheh this program was hiding some secrets

With RESOLUTION, maybe you mean flags 20 & 27 ?
20 is 1 flag
27 are 4 flags (20 + 4 + 2 + 1)
The programs that can read SFO's (SFO editor by hellcat , SFO reader by deroad, etc...) shows the values in "big endian", but inside the file are stored in "little endian", i listed both in the table because i prefered not to depend of programs
http://www.ps3devwiki.com/wiki/PARAM.SFO#RESOLUTION
I copyed this ones from "SFO editor" made by hellcat, im not sure if others can be valid but there is space for 32 flags

Dont worry to add info in pages that are not finished (most of the wiki is not finished), just try to be precise and give most details as possible for others to verify it
Somebody will move or rewrite it later, or if its an obsolete example removed (if needed)
I did this a lot in the PARAM.SFO page, it was the only way to "clean up" my notes i had in my PC writed months ago (actually all my notes are erased in my PC thanks to this and all i had is in ps3devwiki, nice)... sorry for this to the wiki readers btw, but i had no other way to do it

With officiall tools... is better not to base the discoveryes on these, even considering that are leaked lot of times and spreaded over and over in internet. Cant be included in ps3devwiki because is copyrighted stuff
Is better to appart of them, and are no really needed, we can use examples from discs or packages, or reverse engineering the firmware functions
This is why i began by "reversing" the SFO structure ---> then "recicle" all the info from old programs (like SFO editor) ---> then recicle all the info from google forums ---> looking/deducing how discs and packages works ---> lot of experiments
SFO format is inherited from PSP (lot of years old and used for firmware modifications in some way in PSP), it has no kind of protection itself. In PS3 they decided to use the same format and you can look his SFO's from day 1 (in the exported savegames), later is reused again in PSvita, so i consider the format is old and known enought to be almost 100% public, but still... is better not to depend of officiall tools, the point of all this is to replace all them
