Sony has announced that Mainichi Issyo, its free PlayStation Store PS3 download, can be played on the PSP via remote play. By activating remote play, you can interact with Toro the cat through your PSP wherever you manage to find an internet access point.
So does this mean that we can look forward to Heavenly Sword and Lair on the go? Probably not. Mainichi Issyo is a passive game where you simply select options from a menu and watch the results. There's little concern over lag. In fact, the few timing-based mini games in the game are not compatible with the remote play feature.
