*The firmware versions listed here consist of the SOC type letter:
- R - CXD2677 (Type R)
- S - CXD2678 / CXD2680 (Type S)
- Hn - CXD2681 (gen1)
- Hr - CXD2681 (gen2)
- Hx - CXD2687
And the actual firmware version reported by the device.
**WaitForDiscToStopSpinning only supports Type-S devices, on Type-R and HiMD it always waits 10 seconds.

If you would like to help with adding compatibility for your device, pull requests are welcome.
The library keeps track of what exploits are compatible with what versions with the help of src/compatibility.ts.
Every exploit class has to inherit the Exploit abstract class. It provides multiple functions which make it easier to load the correct versions of exploits for every firmware version.
The constants that depend on the firmware version are stored in a VersionStore map returned from getPropertyStore(), from which it's possible to get values by calling getProperty, or by referencing their names in assembly code, prefixed with a '$'. Every exploit class has to also define a static _name const, used for compatibility checking.
Once an exploit is loaded using ExploitStateManager.require or ExploitStateManager.envelop, the exploit's init() method is called. Because of how exploits are loaded, exploits shouldn't
have their own constructor. Instead, init() should be used as an asynchronous constructor.
To unload an exploit you can use ExploitStateManager.unload. When using ExploitStateManager.envelop, this action will be done automatically.
When an exploit is unloaded, its unload() method is called, where the exploit can perform cleanup.
All behavior-modifying exploits should have a valid unload() method defined, in order to automatically restore the device to the default state.
If an exploit is using patches, the unload() method should clear the patches from the device, and then call this.stateManager.freePatch(), to mark the patch as unused.
All the patches for which ExploitStateManager.freePatch() wasn't called will automatically be unloaded from the device by the state manager.
If a patch is loaded by ExploitStateManager.require, and then reloaded again using ExploitStateManager.envelop, it will not be unloaded after returning from envelop().
To unload it, ExploitStateManager.unload has to be called.
The assembler has full support for macros (prefixed with '@'), VersionStore constants (prefixed with '$'), as well as variables, passed to the assemble function (prefixed with '%').
The macros available for every assembly program are stored in src/assembler/core-macros.ts.
Exploits can define private macros in the _macros property of the VersionStore returned from getPropertyStore().
Happy hacking!
Below is an extremely basic example, which when run will download the first track from the disc onto the computer using the best suited exploit for it:
import { DevicesIds, openNewDevice } from 'netmd-js'
import { AtracRecovery, getBestSuited, ExploitStateManager } from 'netmd-exploits';
import { WebUSB } from 'usb';
import fs from 'fs';
(async() => {
const usb = new WebUSB({ allowedDevices: DevicesIds, deviceTimeout: 1000000 });
const dev = await openNewDevice(usb);
const stateManager = await ExploitStateManager.create(dev!);
const exploit = await stateManager.require(getBestSuited(AtracRecovery));
fs.writeFileSync(await exploit.downloadTrack(0, console.log));
await stateManager.unload(getBestSuited(AtracRecovery));
process.exit(0);
})();The assembler built into netmd-exploits is a modified version of keystone-js by AlexAltea
