What is PackJSNES1 and how does it work?
- A game editor that lets you design your own levels, sprites, tiles, palettes, sounds, and music.
- A game packer that bundles your game assets into a single file that can be easily distributed.
- A game loader that lets you load and play your game from a URL or a local file.
PackJSNES1 works by emulating the NES hardware and software in your browser. It uses HTML5 canvas to render the graphics and Web Audio to play the sound. It also uses localStorage to save your game progress and settings. PackJSNES1 supports most of the NES features, such as:
- 256×240 resolution with 64 colors.
- 2×2 pixel attribute table with 4 color palettes per name table.
- 64 sprites per scanline with 8×8 or 8×16 size and horizontal or vertical flip.
- Background scrolling with horizontal or vertical mirroring or four-screen mode.
- Sound channels with pulse, triangle, noise, and DPCM waveforms.
- Mappers for ROM switching and bank switching.
PackJSNES1 also supports some extra features that are not part of the original NES specification, such as:
- Custom mappers for more ROM space and functionality.
- Custom palettes for more color options.
- Custom sound effects and music formats for more audio variety.
- Custom input devices such as keyboard, mouse, touch screen, gamepad, or accelerometer.
