The problem being several-fold..
1) I own no DVD Rom.
2) I'm not really interested in the models, but how the textures are shaded. I'm trying to figure out if they are a combo of vertex shading, or if the UV maps are "all in one" I'm having a very hard time trying to find tutorials on how to properly shade a 3d model in that particular style. The texture mapping in Japanese RPGs are wholly unique, so even just a screenshot of a low resolution UV map with with word "SAMPLE" through it would be fine. I'm not trying to rip them, I'm trying to learn from them.
to answer question number 2. they use a form of baking, and then go to work on them using photoshop. a lot of artists are capable of painting this way without baking, it's just that baking is faster if you're trying to get the whole model (what's a texture without a model to put it on?) to look coherant, with the same lightsource all around.
one of the better baking tutorials i found was at
www.bobotheseal.com . bobo does an awful lot of hand painted, pixel level art. and is truly a master of what he does.
i don't understand what you mean about the texture mapping in japanese RPGs being wholly unique though... if you're referring to the UVW map itself, then no, not really. like most professional studios, squeenix are very good at utilising their texture space properly, to get the most efficient maps out of their models, which of course, gives better texture results. it's the style itself which is quite unique, as it tends to have an anime feel while still looking fairly realistic. if you're looking to emulate that particular style, could i suggest browsing some DBZ forums and things like that with reference in particular to games. half life has a mod called ESF which has a very similar painting style to its models, and a lot of the fan work there is quite close. there is one artist there called Enix, who loves to whore that particular style. along with PiXel.
good luck, if you have any specific questions, or have any textures of your own which you would like some critique or a paintover or something, give me a shout. if i have time i'll help all i can.
