Sprites.org
Free browser editors for the graphics, sound and data that go into games, for modern pixel art and for retro machines.

About
Sprites.org gathers a family of editors in one place: sprites, images, fonts, text, maps, audio, 3D, data and code. Most come in a freeform version for modern work, and in versions for the classic machines that stay within their palettes and limits.
The retro editors cover the Spectrum, C64, NES, SNES, Game Boy, Amiga, BBC, Oric and the PC, with a reference section on each platform and each kind of media alongside.
Features
Sprites & images
Pixel sprites and full images, freeform or held to a machine's palette, from VGA to Teletext.
Fonts, text & maps
Character sets, text screens and tile maps for the consoles and home computers.
Audio & 3D
Sound for each machine, MIDI and MOD, and voxel, isosurface, ray-marched and splat scenes.
Data & code
Binary, grid and structured data, and code editors for each machine and for reactive interfaces.
True to the machines
Retro versions for the Spectrum, C64, NES, SNES, Game Boy, Amiga, BBC, Oric and the PC, held to each one's palettes and limits.
Reference
Each kind of media and each platform explained, alongside the JavaScript library behind the editors.
