About Artemis OS 3DS

Windows can be dragged around and closed, and the taskbar has a Start menu, a clock and a battery meter. The bottom screen is a trackpad and an on-screen keyboard.

The apps are Notes, Paint, a calculator, 9x9 Minesweeper and a file explorer. Notes and Paint pictures are saved in /3ds/artemis/, and the file explorer only looks in that folder.

- Stylus on the trackpad: move the cursor, tap to click
- A or L: click
- R: right click, which flags Minesweeper squares
- B: close a window
- D-Pad or Circle Pad: nudge the cursor
- Start: Start menu
- Select: quit

Sound needs the DSP firmware dump made by DSP1. The About window tells you if audio didn't start.
