Come vedete e facilisimo instalarlo,neanche 1 giorno e ci sono gia tutti i emulatori di console 8-32 bit(MAME,Neo Geo,NES SNES GENESIS GBA ),i giochi iso si instalano diretamente sul HDD e la ps3 li riconosce come giochi PSN ma la cosa piu bella e che se si instalano e si torna al firmware originale tutto rimane!Per il momento Sony non ha rilasciato nessuna dichiarazione,quindi non si sa se banerano console o meno(con la psp non l'hanno mai fato pero...)
