DOS Direct

DOS Direct is an emulation backend based on dosbox, you can create it with following command:

const ci = await emulators.dosDirect(bundle);

In theory direct version is fastest possible version of emulator backend. But it have strong disadvantage: it's working on main browser thread. So it can easily hangs browser for some amount of time, and not very responsive.

note

DOS Worker is more preffered version of emulator backend, because it not block the browser.
