Whats up with the packs? I know how to get them and stuff but I'm on vacatiuopn and I'm at a friends house. They do have WiFi but I forgot my PSP. So I don't know whether or not to get them or what the hell they do. Because if it doesnt do anything I don't want to waste my memory space. So please just tell me what they do and which ones are worth getting and which ones I shouldnt get. Also I heard that they won't be able to obtain them forever so if you could tell me whether or not they're still available that would be great. Thanks

I tried the offical website but the links are dead. Does anyone know of other sources where I can download the game packs?
