Yes dude, they are all full firmware versions.
But not 'upgrades' for currently working players.
I wouldn't recommend using them unless your player is dead because even though they say they are... i know for a fact a few of them 'are not quite right'
Take the Full Metal Platinum 1.5 firmware at the bottom of the page for example. It's not for a 1.5 inch screen, it's for a 1.8. and the FMP 1.5 takes fw9.0.48 and that version on the site is 9.0.49
