The Atari 8bit computer emulator, Atari800, has been updated.

New features:
- Auto-download missing OS/BASIC ROMs from the Internet
- Mount zipped disk images directly from the Internet
- Portable mode — config file and data storage next to the executable

Platform specific:
- Windows: 32/64-bit builds, installer executable, portable zip archive
- Windows: app icon, MP3 recording support
- Windows: win32-no-network build for XP compatibility
- macOS: ready-to-run .dmg archive
- Linux: AppImage builds (x86_64 + i386)
- Android: auto-download ROMs, upgrade dialog

Changes to config file search order:
1. --config argument — exact path given on command line
2. Portable exe dir — exe_dir/.atari800.cfg if exe dir is writable
3. $HOME default — ~/.atari800.cfg (if neither of the above applies) plus $HOME now respects MS Windows specifics (USERPROFILE etc.) If the resolved path (1, 2, or 3) doesn't exist:
4. HOME fallback — try ~/.atari800.cfg (only in portable mode)
5. System-wide — /etc/atari800.cfg (only if steps 1-4 all failed)
6. Fresh defaults — create new config at the path from step 1/2/3
