I got a Beatmania controller, Tatakon (Taiko Drum Master controller) for PS2. Hooked up to PS3 via an adapter, launched Taiko Drum Master. "Press PS button" Well, shit. There's no PS button on tatakon. Tried every button, buncha combinations of buttons, holding START for 2 minutes (not literally), all failed. And yet us.playstation.com backwards compatibility list says "No major problem with this game." So.. Uh.. No controller recognition is not a problem? What, I have to use Dualshock 3 to play Taiko? I'm so mad. Like, I haven't been this much pissed in the last 9 years or so. Was it really hard to add a PS2 controller slot on PS3, when even compact sized Wii has gamecube controller slots? The game itself runs smoothly and looks good. But if I wanted to play Taiko with buttons I'd play the PSP version which even has DLC, instead of looking like a nerd playing a Taiko game with Dualshock 3 listening to Jackson 5's ABC.
