yes after reading a bit i understood you are using the warning errors (format_num=* and... reserved bits) to identify them

I noted all the examples you wrote but maybe are too much to discuss one by one (and probably some ones are things that you realized later)
Have not tested/seen myself, so im not 100% sure if the ATTRIBUTE table must be rebuild (separating the fourth byte in hexadecimal values)
I prefer not to make big changes in the page before im 100% sure about the theory is correct (and this one seems valid, but im not 100% sure... another example from a "officiall" content can be decisive)

The point is this hexadecimal values can be done with combinations of flags (in binary)... we have from X1 to X7 that can be done with different additions of flag Nº 25 (00 00 00 01), Nº 26 (00 00 00 02), and Nº 27 (00 00 00 04)

After this (if you want to make an "8")... you have to use flag Nº 28 (00 00 00 08) and this gives you an "reserved bit error"... maybe this flag is used for other feature... maybe is reserved... maybe is an error, we cant be sure

And the next one (if you want to make an "9") you need to use flag Nº 25 (00 00 00 01) + flag Nº 28 (00 00 00 08)
The flag Nº25 (00 00 00 01) defines the content as X1 (you return to the beggining)
And flag Nº28 (00 00 00 08) gives you the "reserved bit error"

So its clear for me that whatever this X0/X7 are refered.... only is valid if using flags smaller than Nº 27 (00 00 00 04)

-----------------------
Btw... i just cleaned-up a bit the page (mostly the tables, that are more intuitive now), the ones for "CATEGORY in HDD" and "Parameters Table" are pretty nice for me (both matches in severall ways, both has all the 18 different CATEGORY's in HDD listed)

There is an "easy" thing is not documented yet.... the "PP" format
We need an example of one of this PARAM.SFO (is a PSP game when displayed in XMB inside a bubble)
And we need to fill his "PP" column in the "Parameters Tabe" ---> http://www.ps3devwiki.com/wiki/PARAM...rameters_Table

Can somebody do it ? (uploading the PARAM.SFO here is enought)

Edit:
Btw... this "PP" file example is needed, i bet it contains new parameters not documented (e.g. something like PREINSTALL_PSP) or something common with "PSvita" for the transfer/preinstall feature
