  • The first step of the PPU rewrite has concluded. I rewrote the sprite core from scratch in order to match the NES hardware procedure. Actually, it's not 100% accurate yet, though I'm working on it.
  • Be sure to read the RockNES forum for the latest news.

  • 2008, JAN 25 [FRI] -RELEASE-
  • Update: version beta 4b released, fixes 22050Hz setting and removes debug stuff left.

  • With ten years of development, RockNES was a fork of xNES in early times, but no more since its complete rewrite. Actually, RockNES is 100% coded by myself - the only third-part resource is the Allegro library. To celebrate the 10th anniversary, here's a new release. I hope you enjoy it and give me some feedback in the forum!
  • This 4th beta release is a major step. The old problem with the video has been solved - running at 60Hz, meaning smooth emulation.
