Update of the MenuetOS 1.63 operating system, written in assembly language

The release of the MenuetOS operating system version 1.63.0 has been published, with its kernel entirely developed in assembly language. MenuetOS builds are prepared for 64-bit x86 systems and can run under QEMU. The system build occupies 1.4 MB and is available as a floppy disk image and an ISO image for CD burning (launching in VirtualBox is supported). The source code of the Menuet64 project is distributed under a restrictive license, requiring agreement for any commercial use, while Menuet32 is under the GPL license.

The system supports preemptive multitasking, booting on UEFI systems, and SMP on multi-core systems. The project is also developing its own X server and provides a built-in graphical user interface that supports themes, Drag & Drop operations, UTF-8 encoding, and keyboard layout switching. A custom integrated development environment is offered for application development in assembly language.

The operating system includes a network stack, drivers for Ethernet and USB 2.0, AC97 and Intel HDA (ALC662/888) audio codecs. The project is developing a simple web browser called HTTPC, along with mail and FTP clients, a VNC client, FTP and HTTP servers, applications for viewing images, editing texts, managing files, watching videos, and playing music. The NDN (Necromancer’s Dos Navigator) file manager is suggested for file navigation, which has been ported for MenuetOS.

A DOS emulator is available, allowing the launch of games such as Quake and Doom. Compatibility with Linux is provided through a basic POSIX layer that allows the creation of GUI applications that can run in both Menuet and Linux/X11, as well as a custom X server written in assembly language that can redirect output from applications running on an external Linux system to display their interface in MenuetOS.

Recent changes include:

• An emulator has been added for running games developed for GameBoy consoles.
  
• Support for TrueType font format has been added.
• Code optimization has been carried out for establishing secure network connections.
• New system calls have been added for window management.
• A port of the game Wizord EXL100 has been implemented.
• Tools for driver development have been expanded, and new features have been added for network, audio, MIDI, and graphic drivers.
• Improved implementations of the FTP server and FTP client.
• Enhanced QR code reader application.
