Questions

Good to know

Is MesoLens safe to use with MapleStory?

MesoLens only reads your screen, the way a screen recorder or streaming software does. It never reads or changes the game's memory or files, never injects anything and never presses keys or clicks for you. It's a fan-made tool and not approved by NEXON, so like any third-party tool, using it is your call.

What does the game need to be set to?

Windowed or Borderless (windowed full screen). Exclusive full screen hides every overlay.

Windows says "Windows protected your PC". Is that normal?

Yes. MesoLens is new, so Windows warns about it the first time. Click More info, then Run anyway. You can check the installer's SHA-256 on the download page.

How do I cancel, pause, or get a refund?

On your account page: cancel any time and keep your perks to the end of the month, or pause for 1 to 3 months (no charge, then it restarts by itself). No email needed. Refunds are covered in the terms, or write to [email protected].

I have a streamer's creator code. Where does it go?

When you subscribe: on your account page (pick a plan, then "Have a creator code?"), in MesoLens (Settings > Account), or on Stripe's payment page. It gives 20% off your first 3 months of your first subscription. Streamers who want a code can write to [email protected].

Can I show MesoLens on my stream?

Yes: turn on Settings > Streaming > "Show MesoLens on my stream" (it's hidden from streams until then). In OBS use Display Capture: Game Capture only grabs the game itself.

Does it work on Mac or Linux?

Mac: yes, in beta, for macOS 12 or newer (Apple chip or Intel): get it on the download page. Linux: not yet.

See the Free Market the way traders do.

Free, about a minute to install, and it never touches the game.
