Some original resources. I'm checking though character resources, not sure if there are rips or not. But none the less, these are great quality resource.
Oh hey, I just realised I should be in the list! http://hypercrescendo.net/foxlee/fls/bmg (sprites in the 'Resources' section... okay, I don't have many yet, but I'm working on more! XP).
People who need some good icons and don't mind ones from commercial games should definitely look at http://fogu.com/hm/ in the Rune Factory (DS) section. There are more than 600 RMXP-sized icons from this game on the site and they are all very good. (It's not RPG Maker site. You have to look in the texts for them.)
PS: If you use them, don't forget to give credits to both the game and Fogu!
