In the bar below press «Download runtime». It downloads once and the app keeps it in its own folder, apart from any other copy of the game you have.
Press «Choose ROM» and pick your .nes file (if it's in a .zip or .7z, extract it first). The app checks it is the original Super Mario Bros.; if not, the step turns red and tells you why.
The exact list of versions that work and don't is behind the help icon in the bar below.
Press «Enable connection» with the game closed: the app downloads what the game needs to receive effects and puts it in place.
The first time, the game reads your ROM and builds its graphics in a few seconds: don't close the window meanwhile. After that it starts straight away. It opens in widescreen (16:9); you can change it in the game's own Settings.
Before that first launch the app shows you these steps in a window.
When the bar below shows «Connected», pick Super Mario Bros. on the game selection and start with Z (A on a controller). Effects land while you control Mario.
In «Profiles» create an example one in a click or build your own: each gift, follow or chat command fires the effect you pick, with as many enemies as you want.
Each effect is assigned to a gift, a follow, likes or a chat command.

Enabling the connection and uninstalling the runtime are done with the game closed.
Effects that arrive on the title screen, in menus, while dying or between levels wait in a queue and fire as soon as you control Mario again (for up to 10 minutes).
