you need to add them to QQ and pay yes. Not sure if they're even still actively doing it. Site seems to be updated since i last looked at it though.
You should probably note that a lot of stuff on this site isn't theirs, they take a lot of stuff from lomcn and other resources then sell them on as their own. Most stuff on there can be found for free on other sites if you search hard enough.
Not exactly right.
90% of these resources are from chinese Web Games.There are thousands of Web Games in China.
They play the games,then your will find many .swf and .jpg .png files in the Temporary Internet Files .
Then you can use swf extrator to extrat .swf files to .png file.These are maybe Weapon resources,Item,Cloth,Monster and so on.
The "晨风(Morning Wind)" map tool can use the .jpg files,and combine them to be a complete map original painting .bmp file.
