SonicCD++ (or Sonic CD Plus Plus) is a hack of Sonic the Hedgehog CD by qiuu and snkenjoi, adding the Sonic the Hedgehog 2 (16-bit) style Spin Dash and the newer Homing Attack into the game. This enables the gameplay to be significantly speedier, while Sonic CD is known to be one of the more slow-paced games in the classic Sonic series.
