Jump Pack, Vibration Pack, Puru Puru Pack and dualshock ps2 all on Sega Dreamcast.

[aldair]

5 volts is not enough for the vibration of the ps2 control which uses 9 volts for its full vibration.
If you see the video well you will see the ps2 control vibrating strongly with 12 volts. The jump pack doesn't vibrate like that!





If you have this adapter with input for 12 volts will have full vibration now!
