What both publish
| Fact | JSNES | Nesalizer |
|---|---|---|
| Audio | The API supports an audio callback and has sound emulation enabled by default with a default sample rate of 48000 Hz. | During rewind, audio is added in reverse from the end of the audio buffer. |
| License | The repository identifies its license as Apache-2.0. | The project is licensed under GPLv2. |
| Purpose | JSNES is a JavaScript NES emulator library that works in browsers and Node.js. | Nesalizer is a work-in-progress NES emulator with real-time rewind that correctly reverses sound. |
| Save states | The API can serialize emulator state with toJSON() and restore it with fromJSON(). | Save states are in memory and are not saved to disk; persistent on-disk save states are listed as missing. |
