Here's a quick update with this month's changes.

UX:

• Updated FAQ

• Added a warning if some emojis aren't supported

• Nametable inspection now works while the debugger is paused

Improved docs and explanations:

• Explained how to edit files in 5a.16

Improved tests:

• Added a test ensuring [c]onFrame(...)[/c] is called at the right time

• Added an extra Noise Channel test

• Added a test ensuring [c]CPU::step()[/c] doesn't crash if [c]logger === undefined[/c]

Fixes:

• Prevented closing video or audio test subpanel while they are running

• Fixed Ctrl+C not working in CodeMirror while ImGui is running

• The game now waits for BrowserFs's AsyncMirror to sync before navigating (fixes potential snapshot corruption)

• Fixed example code in level 5b.10
