Proto:Sonic the Hedgehog 2 (Genesis)/Beta 7

Cheat codes

 * Level Select code: Up, Down, Down, Down, Down, Up, highlight 1 player, then press A + Start.
 * Debug code: C, C, Up, Down, Down, Down, Down, Up, highlight 1 player, then press A + Start.

General

 * "Sonic and "Tails" in" appears instead of "Miles 'Tails' Prower."
 * Sound does not stop when the game is paused.
 * Only Up and Down work at the level select.
 * Sound test option at level select is glitchy until highlighted.
 * "Option" instead of "Options".
 * "Sonic only" and "Tails only" instead of character name alone.
 * This is the first Sonic 2 prototype since Beta 4 where Debug works.
 * Robotnik's final robot still starts in the center.
 * The laser sound effects that hit Tails' plane are slightly different.
 * Boss music doesn't play during Wing Fortress Zone boss.
 * When Sonic jumps onto the biplane at the end of Wing Fortress Zone, the jump sound plays twice.
 * In the Special Stage, the "(x) rings to go!" message is active; it was not in previous betas. However, even if you have 0 rings to go, the message stays on-screen until the "Cool!"/"Not Enough Rings..." message appears instead of disappearing as in the final.

Bugs

 * When a level is clear with Super Sonic, Sonic doesn't change back to normal Sonic and the ring counter still drains rings until it hits zero.
