Sega Console Game Boot Screens

Background
From the Mega Drive/Genesis to the Dreamcast, Sega made these screens on those consoles' BIOS when a game is loaded into the system. This was originally done to prevent unlicensed developers' games to work with Mega Drive/Genesis systems, since the massacre of unlicensed Accolade games. But since the majority of unlicensed independent, pirated, and hacked games for the Dreamcast being playable on the console, the screens later served no purpose but to notify the gamer that a game has been accessed, just with the appearance of it.

1st Screen (October 29, 1988-1998)
Logo: We see the text reading "PRODUCED BY OR UNDER LICENSE FROM SEGA ENTERPRISES LTD." centered on a black screen approximately for three seconds.

Variants:
 * On the Game Gear console, the background is blue.
 * On few Absolute titles for Genesis, such as Toys (1993), the screen fades in and out. Plus, the text is in a different font.
 * Games with region lockout will display a message if attempted to be played on an incompatible console.
 * If a Japanese cartridge with region lockout is played in a non-Japanese machine (via a Game Genie), it will say "Developed only for use with NTSC Mega Drive Systems".
 * If a European cartridge with region lockout is played in a non-European machine, it will say "Developed only for use with PAL and French SECAM Mega Drive Systems".
 * If an American cartridge with region lockout is played in a non-American machine, it will say "Developed only for use with NTSC Genesis Systems".

FX/SFX: Nothing but a text display.

Music/Sounds: None.

Availability: Can be displayed when a Sega Genesis/Mega Drive and Sega 32X both manufactured from 1991 onwards is booted up with a licensed game placed on the cartridge slot. It also appears on Game Gear manufactured when it was turned on.

Editor's Note: None.

2nd Screen (November 22, 1994-2000)
Logo: We see the Sega logo with the words "PRODUCED BY or UNDER LICENSE FROM SEGA ENTERPRISES, LTD." below on a black background.

FX/SFX: None.

Music/Sounds: None.

Availability: Can be displayed when a Sega Saturn manufactured from 1995 onwards is booted up with a licensed game placed into the CD-ROM drive of the Saturn.

Editor's Note: None.

3rd Screen (November 27, 1998-2006)
Logo: On the same background as the Sega Dreamcast logo, we see the Sega logo on the left and the text "PRODUCED BY OR UNDER LICENSE FROM SEGA ENTERPRISES LTD." on the right. In later years, the text is changed to "PRODUCED BY OR UNDER LICENSE FROM SEGA CORPORATION".

Variant: An odd variant has the Windows CE logo on the bottom-right. This can be found on games that support CE technology, such as Sega Rally Championship 2 (1999).

FX/SFX: None.

Music/Sounds: None.

Availability: Can be displayed when a Sega Dreamcast manufactured from 1999 onwards is booted up with a licensed game or some home brew is placed into the Dreamcast's GD-ROM (basically a CD-ROM, but 1 gigabyte as opposed to 700 megabytes) drive.

Editor's Note: None.
