New PS1 games hit the Japanese PSN

Love obscure Japanese PS1 games? As both American and European PS Stores continue to get neglected with PS1 games, Japan continues to expand its library with four new titles this week:
Spyro the Dragon
Addie no Okurimono
Gakkou wo Tsukurou
Kawa no Nushi Tsuri
According to
Siliconera, the most obscure title of the list, Addie no Okurimono, "is a puzzle game developed by Sony Computer Entertainment that gives players a Da Vinci Code-like toy to spell words." There's so many random games in Japan that just never come out here, huh?
