UberNES Features

Leaderboards Record your best high scores and speed runs in classic NES games

  • UberNES will automatically save your high scores in 50 classic NES games including Pac-Man, Donkey Kong, and Tetris.

  • UberNES will also track your fastest speed run times in 10 classic NES games including Super Mario Bros, Metroid, and Mega Man 2.
  • Your high scores and speed run times will be recorded and preserved in your "NES Database" file.

Worldwide Rankings Compete for the worldwide high scores and fastest speed runs

  • After downloading the latest UberNES stats, you will be able to see the high scores and speed runs of other UberNES users.
  • If your scores and speed runs are good enough, you will be listed on the UberNES leaderboards after you upload your stats
    • Stats uploading is completely anonymous aside from an optional user name and location that you can provide
  • UberNES takes great care to prevent cheating; use of saved states, Game Genie codes, in-game cheat codes, CPU slow-downs, etc are all monitored and handled accordingly.

History Tracking View the evolution of the leaderboards for each game

  • The history viewer shows a graphical and textual display of the game's history.

  • The two displays are integrated with each other; selecting an event in the textual display will cause the corresponding element in the graphical display to highlight and vice versa

Game Browser Bring your NES collection to life

  • Rather than using the standard "Open a file" window, UberNES provides a rich and fully featured game browser that makes it fun to choose which game to play next
    • When you select a game, all kinds of information about it will be displayed. The publisher, developer, release date, and even the box description from the back of the original package will be displayed
    • If you have box art images on your computer, UberNES will display the box art for each game
    • Statistics from the UberNES leaderboards including high scores and more are also displayed in the game browser
  • In order to provide this feature, UberNES must create a "NES Database" by scanning your ROM collection
    • Creating a database is extremely fast and simple
    • It is even easier to re-scan your ROMs if you download more games and need to update your database. Re-scanning your ROM collection is robust and you are guaranteed to never lose your gameplay stastitics (high scores, speed runs, etc)

Movies Record and playback your NES movies

  • UberNES can record and playback gameplay movies. All of the standard movie functionality is provided through a nice movie console window.
  • "Checkpoints" can be added to movies to mark key points
    • Checkpoints allow you to jump immediately to various points in movies.
    • Checkpoints can also make the movie seek function operate much faster.
  • Movies are stored in a compressed format - 20 minutes of gameplay typically compresses to only 5 KB.
  • NES controller overlays can be displayed as movies play, showing exactly which buttons are being pushed.
  • A local movie gallery makes browsing, playing, and managing your NES movies easy.

Debugging Take a look inside the NES

  • UberNES offers a rich set of debugging tools for those interested in seeing how the NES works or debugging NES programs.

    • Trigger various interrupts
    • Change the CPU registers
    • Adjust the computational increment (for performing instruction traces, frame traces, etc)
    • ...and much more
