Sonic and the Secret Extended Edition (previously known as Sonic 1: The Other Extended Edition, not to be confused with Sonic the Hedgehog Extended Edition) is a hack of Sonic the Hedgehog for the Sega Mega Drive/Genesis by Hayate. It was discontinued in August 2008, after Hayate gave up on the hack due to the various bugs it had, but it was picked up again in December 2009.

Sonic: South Island Warped is a currently in progress hack of Sonic the Hedgehog. It's main point of interest is the return of the time travel mechanic from Sonic CD, along with a few other new features added to set it apart from the original Sonic 1. Zones are split into four acts each; three main acts and and a boss act at the end. Sonic is capable of traveling to the past or the future of the zone he's currently in via the signposts hidden in each of the levels. Each act, sans act four, has a robot generator that, when destroyed in the past, will remove all badniks for the rest of the act and also create a good future for that act. Destroying all three generators for a zone will remove Eggman's influence in the fourth act, which always takes place in the future.Time Stones also return, collectible alongside the Chaos Emeralds. One Time Stone will be hidden in each zone, and it will only be obtainable within the future of that zone. If attempting to retrieve the Time Stone in the bad future, Sonic will have to face off with one of Eggman's machines. If in the good future, the Time Stone will be unguarded and ready to be collected. The fourth act of a zone contains no generators, Time Stones, or signposts, only a boss fight against either Eggman or Metal Sonic. The Chaos Emeralds will be obtained during these boss fights, usually right after the boss is defeated, but you may also be able to reach it before the boss does, preventing it from making the fight more difficult.As of now, this is just a demo of GHZ, which even on it's own is still in need of much work. Honestly there's a lot I couldn't get around to doing just yet, but I still wanted to give everyone a sample of what I'm making. More than anything, I just hope you all enjoy what you play. Everything in this is release was done by me with the exception of the sound driver and the one original song port done for this hack. Both of those were by Varion Icaria who I can't thank enough for helping out. Also have to give a thanks to the many users of both Sonic Retro and SSRG who made all of the informative guides and tutorials hosted on both sites.

Spider-Man and the X-Men in Arcade's Revenge is a video game first released for the Super Nintendo in 1992 by LJN. It was later released for the Sega Genesis/Mega Drive and Game Gear (under the Flying Edge brand) as well as the Game Boy. The game features Marvel Comics characters Spider-Man and the X-Men as they battle their captor, the villainous Arcade.

Super Monaco GP (スーパーモナコGP) is a Formula One racing simulation video game released by Sega, originally as a Sega X Board arcade game in 1989, followed by ports for multiple video game consoles and home computers in the early 1990s. It is the sequel to the 1979 arcade game Monaco GP.The arcade game consists mostly of one race: the Grand Prix of Monaco (though represented by a totally different track, albeit with the same features of the real-life Circuit de Monaco). The player simply chooses a transmission type, qualifies, and race. The player must qualify in under 45 seconds in the shortened track in order to actually race. If he fails, the game ends (though, in the home versions, even if the player fails to qualify, he still starts off the race at the last position). When in the race itself, there is also a position limit, which starts off on 20th (15th in the home versions) and decreases as the player bypasses checkpoints along the track, ultimately stopping on 3rd. If the player falls behind the indicated position and does not manage to recover fast enough, a game over happens.The game was one of the first games to include a rear-view mirror,along with Winning Run. The Sega Genesis/Mega Drive version of Super Monaco GP adds a World Championship mode. In the World Championship mode, the goal is to win a season of races, and then go on to defend the title. The circuits are modeled on the ones used in the 1989 Formula One season, with background scenery similar to the real-world circuit venues, though without the wealth of details the Arcade version had. This Mega Drive/Genesis version was also released in arcades for the Sega Mega-Tech system board in 1990.
