emulator: VirtualXT
type: libretro
source: "https://github.com/libretro/virtualxt"
systems: [ibm-pc]
# VirtualXT is a Turbo PC/XT emulator (Intel 8088/186). Written in Odin.
# All BIOS ROMs are embedded at compile time via #load() directives in
# src/frontend/core.odin. No external BIOS files are required at runtime.
# The default machine setup (setup_default_machine) loads these embedded ROMs:
# - BIOS: GLaBIOS 0.2.6 or Turbo XT BIOS 3.1 (user selects via core option)
# - VGA BIOS: vgabios.bin (loaded when VGA video mode is selected)
# - Disk Extension: vxtx.bin (always loaded)
# - RTC BIOS: GLaTICK 0.8.4 (loaded when RTC is enabled)
# Core option "virtualxt_bios" selects between GLaBIOS and TurboXT at startup.
# Core option "virtualxt_video" selects CGA or VGA (VGA loads vgabios.bin).
# Core option "virtualxt_rtc" selects GLaTICK or none (loads GLaTICK_0.8.4_AT.ROM).
# INI config files (.ini extension) can reference external ROM paths, but the
# standard usage path does not require any files in the system directory.
# Embedded BIOS files (shipped inside the compiled core binary):

notes:
bios_approach: >
VirtualXT embeds all BIOS ROMs into the core binary at compile time using
Odin's #load() directive. The bios/ directory in the source tree contains
open-source replacements: GLaBIOS (GPL), Turbo XT BIOS 3.1, and vgabios.
No proprietary IBM PC/XT BIOS is needed.
ini_config: >
When loading an .ini file, the core can instantiate ROM modules with external
file paths (rom.odin handles string values for "mem" via load_from_file).
This is an advanced usage path; standard operation needs no external files.
supported_extensions: "img, ini, exe, com"
supported_features: >
Intel 8088/186 CPU, CGA/VGA graphics, EMS memory, ethernet adapter,
host file sharing (RIFS2), GDB server, floppy and hard disk images.
