Whoa, thats a lot of text in those links. lol
\o/ let me explain the purpose of the table with the lines.qrc versions
At the left column appears the firmware versions that used the same exact lines.qrc file, as example you can take the lines.qrc from firmware 4.60 (and any version in between) and use it in 4.82 because is the same exact file
If someone made a lines.qrc modification (the modifications made in this file are usualy related with the XMB wave) using a lines.qrc from 4.60 as base... you can use it in 4.82 because it should be 100% compatible
But if we step down to 4.55... you can see in the table the file is different (are grouped by its MD5 btw, to be 100% sure that are the same file)
So if you use a modifyed lines.qrc from 4.55 in 4.82 the results can be unexpected
And i say "unexpected" because we dont really know what was modifyed exactly after 4.55 inside lines.qrc file
The table in wiki has room at the right column to add this kind of details (like a changelog) but i never filled that info (maybe some day) because to make that accuratelly is needed to extract all the files inside lines.qrc (that works as a container and has more than 100 files inside), then check MD5 of all them, compare with previous firmware version, and after identifyed which files has changed... take a look at them to know exactly what they did
Lot of people thinks in the lines.qrc file as if it where simply "the wave" but it contains more than that, a couple of executable .elf files (the wave and sparks animations), 60+ FPO and VPO (program objects) under a "library" path, some tenths of MNU settings for the .elfs (this files are the ones modifyed to make custom waves) and others less important like some images (DDS TGA)
With the DDS and TGA there are not incompatibility problems... unless sony added a new one in between versions, this is obviouslly a problem if you take an old verions where is missing an image needed for 4.82 is not going to work fine
With the MNU files there is no problem either... unless the case mentioned before... if they added some new setting and you take a file without it in a firmware that needs that setting = problems
The changes in FPO and VPO are very important, if there is some change in them is hard to check (i dont even know how to deal with them, is some openGL stuff)
The ELF files i have not checked them, but i guess was not much updated, and even if it was updated, all versions should work in other firmware versions because is an .elf
-----
So as a resume to get the idea...
We know that groups in the wiki table are 100% compatible, there are 27 groups since firmware 1.00 up to 4.82
But we dont know which "groups" are compatible with other "groups" because nobody compared them in detail (if someone does, please add the info in that table in wiki), as example (i think pinky and me was talking about this before and we verifyed it for a couple of firmwares)... it could happen that the only change made in between versions of lines.qrc is simple a color adjustment (small changes in the MNU files)... in this case the groups are compatibles is just the visual effects are different
But as said, we dont really know, personally i prefer not to risk in using a incompatible file
LMFAO!
