Well, they're all rips(taken from other game) but I'm pretty sure they're legal but your game won't be very original if you use sprites from published games. :P
Oh god!
I used that site when I first started messing with sprites... Good times, Good times...
I remember looking on there, finding Chrono Trigger sprites, and making vids for youtube (like Chrono's Techno Dance!)...
Yeah, she ripped those all from published games... They are all main chars (except for a few exceptions) and important pieces of scenery. Most people who play nes/snes games religiously would spot them immediately
or people who play psp and gba a whole lot. But sadly, I cant use the ff tactics stuff for Luso and Balthier :( I don't own a psp or a copy of ff tactics war of the lions.
Yes this site it's ilegal. Drop your weapons you're under arrest.
Just kidding, check out there FAQ and see what they say. http://www.videogamesprites.net/FAQ/
