It can also be accessed from the file menu's special stage selection in Sonic & Knuckles Collection for PC. In Sonic Mega Collection and Sonic Mega Collection Plus, Blue Sphere can be unlocked separately (in the former case by playing Sonic the Hedgehog and Sonic 3D Blast 20 times each) and is accessible by itself from the game listing. In Sonic Jam, it can be accessed by "locking-on" Sonic 1 to Sonic & Knuckles. Locking on Sonic & Knuckles to another copy of Sonic & Knuckles will also load the game normally.īlue Sphere is also available in certain compilation games. Some cartridges with particularly large ROM file sizes (including Phantasy Star IV: The End of the Millennium and Super Street Fighter II: The New Challengers) will not load Blue Sphere, but will instead boot Sonic & Knuckles as normal.

If the cartridge that is locked on to Sonic & Knuckles is the original Sonic the Hedgehog ( Sonic Classics, the Nick Arcade and Simon Wai prototype versions of Sonic the Hedgehog 2 will also work), then the full game of Blue Sphere is accessed with all stages. The scrolling text will be replaced by "Get Blue Spheres!" When a Mega Drive game cartridge other than Sonic the Hedgehog 2 or Sonic the Hedgehog 3 is locked on to the Sonic & Knuckles special cartridge, a screen appears with the Sonic & Knuckles logo, models of the characters Sonic, Tails, Knuckles and Eggman, and a line of scrolling text that says "No Way! No Way! No Way! No Way?" While this screen is visible, pressing, and at the same time changes the screen to the Blue Sphere menu.
