No. Only Rock Band 2 (and I think original Rock Band) controllers are compatible with PS2 and PS3.
no
No. Sorry, the PS3 is all wireless, but it has two USB ports, which means the drums will plug in either PS2 or PS3, but, gay as it sounds, the guitars are not compatible with both systems
No. Try it anyway.
no the Dual Shock 3 controller is Bluetooth and the PS2 does not have Bluetooth, although it would still not work for other reasons
On the PS2 only, Guitar Hero: Aerosmith and newer support PS2, PS3, and Xbox 360 controllers. Drum kits are cross-compatible with the PS2 versions of GH: World Tour and newer.
If you have a GH3 Wireless Les Paul guitar with a USB connection then, YES
No, PS3 wireless microphones are not compatible with the PS2. The PS2 uses a different wireless technology and communication protocol that is not supported by PS3 accessories. Additionally, the games and systems were designed for different hardware and software standards, making them incompatible with each other.
No, the PS2 needs a receiver programmed to the PS2 guitar, whereas the PS3 is fully controller wireless
No you can only use the PS2 drums for PS2 because PS2 drums aren't compatible for Wii or any other console besides PS3
Nope, you can't play a ps3 guitar in a ps2, but if your ps2 guitar gets inserted in the USB port then you can play it on your ps3.
No it does not. The PS3 dual Shock controller is Bluetooth and different than some other wireless controllers. The PS2 does not have Bluetooth and the controller would not work because the PS2 also does not have the supporting software.
