These are all of the Hacked ROMs that we have right now, but we'll be adding many more soon.

Super Mario Bros. Hack - Bowser's Jumping Challenge:  A very fun, moderately difficult hacked ROM for the NES.  Note that I have only been able to make this ROM work on the emulator VirtuaNES.  Click here to see a video of gameplay in the first three levels.

Super Mario Bros. Hack - Super Mario Pro:  Mario runs much faster than normal, all enemies are throwing hammers, etc.  It's definitely harder than the original game.  This ROM has also only been confirmed to work on one NES emulator, VirtuaNES.  Click here to see a video of gameplay in the first level.

Super Mario Bros. Hack - Swimmer Mario:  The levels are the same, but mario swims through all of them.  This concept does make the game significantly easier, but it is still fun to check out.  Click here to see a video of gameplay in the first two levels.

Sonic the Hedgehog 2 Hack:  Sonic 2 Tohaka:  "Tohaka" is the Japanese word for "perfect".  This hack has been praised for its exceptional level design, it's not just a funny or silly hack.  However, it is still a work in progress, as only the first two stages have been modified.  Click here to see a video of gameplay in those two stages.

Super Mario World Hack:  The Second Reality Project (Easier version):  This hack is the best one I've played yet.  The whole game has been modified, and every bit of it was very well thought out.  Don't let the words "easier version" fool you, as this hack is still considerably harder than the original game.  Click here to see a video of gameplay in levels all throughout the first half of the game.
