Welcome to SADX MADNESS!!!
My youtube account, nicoissora, has created cool hacks, but some are made by the legendary SADX hacker 'Dude' but apparently, he's dissapered off the face of the Earth!
Here is some SADX info:
The game was released as an enhanced port of the original Sonic Adventure for the Dreamcast, with several additional features added. The PC version was at first released only in Japan and Europe, but later saw a limited North American release. Sonic Adventure DX includes a mission mode, which included 60 missions to complete throughout the adventure fields and action stages. It also contains a minigame collection, which is comprised of twelve Game Gear games featuring Sonic and friends.
Reviews were generally less positive than those of its Sega Dreamcast predecessor, scoring more than 20% lower than the original release.
The game features all twelve of the Game Gear Sonic games as unlockable bonuses. If the start button of the second controller is pressed, the game screen will split, and two games will play at the same time. Additionally, Gear-to-Gear cable emulation is present, enabling the games that have two-player modes to be played if both players access the proper options within the game. These games were to be included in the Dreamcast version, but were scrapped due to time constraints. The same goes for the reintroduced feature of being able to play as Metal Sonic when collecting 130 emblems. A new Game Gear game is unlocked after the player receives 20, 40, 60, 80, 100, 110, 120, and 130 emblems, as well as after completing 20, 40, and 60 missions. The last game is unlocked upon receiving all emblems and completing all missions.
Games unlockable (in order):
Centuries ago, a water-like guardian bestowed upon the planet seven Chaos Emeralds. These emeralds were a source of absolute power. However, absolute power corrupts absolutely — and it did not take long before wars broke out over who would control the Chaos Emeralds' seemingly unlimited power. A tribe of echidna ancestors of Knuckles responded by creating a singular Master Emerald, which held powers that could control and neutralize the Chaos Emeralds. With the Master Emerald came a guardian spirit. It was said that a rival tribe of echidnas angered the guardian by attempting to steal the Chaos Emeralds and ruining the sanctuary it was protecting. They were all but completely destroyed within a single night and the guardian was never seen again. What was believed to be the guardian was then named Chaos, the God of Destruction, lending its name to the Chaos Emeralds.
In the present day, Dr. Eggman learns of the legend surrounding Chaos. Believing it to be true, he seeks out the Master Emerald and shatters it, freeing Chaos in the process. Eggman's goal is to control Chaos, and use its destructive powers to collect the Chaos Emeralds and conquer the city. To help him, he has created the E-Series robots. When Sonic learns of Eggman's plans, he and his friends spring in to action to stop Eggman and they start another journey for the Chaos Emeralds.
