Download Capcom Arcade Cabinet on PSN or XBLA and you can enjoy the full version of the 1987 arcade classic Black Tiger for free.
This is an old-school re-release done right, with plenty of display options, difficulty settings, Japanese and International versions and online leaderboards with viewable replays of the top ten scores.
I don't own a PS3, but I do know that Black Tiger is an awesome game.
I poured countless coins in Arcades just to finish this game.
Free sounds like a great deal compared to the amount of money I spent.
