Siliconera: "The collection of PlayStation archives in Japan continues. Four more games are online including Puzzle Bobble 2 or Bust-A-Move 2 Arcade Edition as it's known in North America. For 600 yen ($5) you can chain and pop colored bubbles on a PSP or PlayStation 3. Psychic Force 2, a trimmed down and graphically downgraded version of the arcade game Psychic Force 2012, is another Taito game. This was never released outside of Japan. We got Psychic Force 2012 for the Dreamcast though."
