Sony expanded their retro catalog today with a wave of SNK games sold on the Playstation Store in Japan. You can’t beat getting King of Fighters ’97 and Samurai Spirits: Kenkaku Yubinan Pack (never released outside of Japan) for 600 yen ($5). Idea Factory released a handful of games too from their Neverland franchise like Suna no Embrace. Also notable is Guilty Gear, a “rare” game in North America that was localized by Atlus. The fighting games are probably something you want to play on the couch with a friend and all of these PS1 downloadable games will work on your Playstation 3 as well as your PSP. Sony also went back and updated a number of thePS1 downloadable games they previously released to make them play on the Playstation 3.
