Sonic DVD

Sonic DVD is a DVD Rom Game ports of Sonic The Hedgehog, Sonic The Hedgehog 2, Sonic CD, Sonic The Hedgehog 3, Sonic And Knuckles, And Knuckles Chaotix. The DVD game acts like like a Plug and Play, and comes with a DVD set with the games in packed with it. The ports were done by Sonic Team, with Jak's Pacific's help, and Published by SEGA.

The DVD Roms itself.
Each DVD has a ROM for each game, which was built from the ground up. These include stuff like bug fixes, little secrets with each game, and a bonus menu. The Bonus Menus on each disc is like the Gallery from Sonic Jam, where you can watch/look at different pictures and videos of development on each game.

Each game has a SEGA Arcade game with it if you beaten the game (through cheating, or actually playing the game).

That doesn't mean stealing the ROM would be easy, they putted something on there where if you try to steal the ROM onto your computer, your computer would fry up. That also doesn't mean you cannot play it onto your computer, however, this comes with two types of controller ports. These ones are ones for the DVD player itself, and ones for your computer.

Why was this made?
Ever since people were ditching DVDs for online streaming apps, DVDs are left out for people who doesn't have a lot of money. This was mainly targeted at the poor, because of lack of entertainment from them.

This, unsurprisingly, caused a big boom in popularity. which sold well.
