They are ports. In the case of Puyo Pop and Puzzle Pocket they are not 1:1 ports, since they added some crap to make it widescreen. But it's usually just a picture with no use for the game. Mojipittan is a port from either PS2 or GBA (it looks the same on both). Kollon is some arcade puzzle game. I confused Doke Demo Issyo with sth. else, that's the cat game. I don't know about that golf game, probably no straight port, just like dynasty warriors is technically no port either. Still that makes only 4 fresh titles for the PSP, all other are ports, rehashes or just handheldified versions. Does the DS have more? I don't know, but i think not.
