The record

Purpose: dosdoor is a stripped-down, cross-platform DOS emulator built to run BBS door games.
Compatibility: It is derived from dosemu 1.4.0, with sound, graphics, networking, and other subsystems removed.
Supported systems: The README lists tested builds for Linux x86_64 and macOS on Apple Silicon and x86_64.
BBS integration: The project describes dosdoor as a drop-in replacement for dosemu in PhotonBBS doorexec scripts.
Game support: The README lists tested games including LORD, Barren Realms Elite, Operation: Overkill II, The Simpsons, and Darkness.
Serial and terminal features: It supports virtual COM ports mapped to stdin and stdout, UART emulation, BIOS serial services, a FOSSIL driver, and ANSI/VT100 terminal output.
Drop files: It works with standard BBS drop file formats including DORINFO1.DEF and DOOR.SYS, and notes that BRE uses its own setup utility.
Notable limits: The project removes sound, graphics, mouse support, networking, SCSI and CDROM, DMA, joystick, and non-CP437 character sets.
Installation: The README provides a Homebrew installation method for macOS and directs Fedora/RHEL users to download an RPM release or build from the spec file.
License: The repository identifies the software as GPLv2, inherited from dosemu.
Pricing: The repository page provides no product pricing information.
