Virtual Filesystem

Virtual Filesystem

The virtual filesystem is a JavaScript object defined in prompt/index.html. It simulates a single drive (C:) with directories and files. Each file either opens an online emulator URL or runs a batch script.

✓ = working in-browser emulator available — = no in-browser emulator; directory exists but nothing can be launched

Console System Layout

Each console system with a ✓ follows a two-level structure:

SYSTEM\
├── launch.exe          opens the main emulator library page
├── menu.bat            box-drawing menu: 1. Launch  2. Browse Games  0. Back
├── 1.bat               runs launch.exe
├── 2.bat               cd games && menu
├── 0.bat               cd .. && menu
└── GAMES\
    ├── menu.bat        numbered box-drawing menu of all game titles
    ├── 0.bat           cd .. && menu  (back to system menu)
    ├── 1.bat           runs game 1
    ├── 2.bat           runs game 2
    ├── ...
    ├── adventure.bat   link → online game page
    ├── asteroids.bat   link → online game page
    └── ...

Navigation example from the ATARI menu:

1           → cd 2600 / menu    (system menu)
2           → cd games / menu   (game title list)
1           → adventure         (launches Adventure)
0           → cd .. / menu      (back to system menu)
0           → cd .. / menu      (back to ATARI menu)
