optional 3.15 firmware update on PS3 only to find that none of your PSP Minis were working on the PS3? You're not alone! The team at PSN Stores has compiled a list of all the Minis that work on Sony's home console -- a whopping five: Blast Off, Echoes, Kahoots, Stand O' Food and Zombie Tycoon.
But what about the remaining Minis? Unfortunately, you'll have to wait a week before the whole lineup is expected to work on the PS3. That means, at least for one week, your copy of Sudoku will remain exclusively on your PSP. Why Sony decided to release the firmware update so long before the feature, ahem, works is beyond us.
