The '''Missing PRESS START BUTTON text glitch''' is a glitch that occurs in the Sega Mega Drive/Genesis game Sonic the Hedgehog. The "PRESS START BUTTON" text that appears on the title screen in early prototype screenshots never appears in the final game, unless it is hacked. |

The glitch occurs because RAM isn't properly cleared, the byte that allows the text to be shown is shared with the two previous screens before the Title Screen and therefore the value is stuck in a no call state, rendering the text to never show up. A more thorough technical explanation of the glitch and fix can be found in this topic from Sonic Retro.([http://forums.sonicretro.org/index.php?showtopic=10240 see here]) |

Missing percussion glitch
The missing percussion glitch is a glitch that occurs in the Mega Drive/Genesis game Sonic the Hedgehog. The sound driver fails to load the drum samples for the music playing, due to the fade in routine after collecting an extra life. Collect an extra life and immediately pause once the extra life jingle stops, before the music fades in. The percussion track in the music will no longer play.
Notes
If the glitch is performed in the Special Stage, FM Channel 6 is disabled instead since this track has no percussion. The game doesn't need to be paused while performing the glitch while in the Special Stage, after gaining a life FM Channel 6 gets disabled. This glitch will not work in the Sonic Mega Collection port, and it is the only version of the game that the glitch will not work in.
