MartyPC v0.2.2 is released. MartyPC is a cross-platform IBM PC emulator written in Rust. Development began April, 2022. It should build on Windows, Linux and MacOS (Including M1)

MartyPC Changelog:
Known Issues
You may get a Windows SmartScreen notification that this application is 'unknown'. You will need to click 'run anyway'. The MartyPC Windows executable is signed via Sectigo; I have done all I can think of to appease Microsoft, and not sure what else to do. This is NOT a malware warning.
WGPU support for older Intel integrated GPUs has moved from DirectX to OpenGL. If you are running integrated Intel graphics and experience poor performance, please set the following user environment variable:
WGPU_BACKEND=gl
macOS users on Intel may experience colored stripes on the screen in fullscreen mode. Enable macos_stripe_fix in the configuration to resolve this.
New devices
LoTech 2MB EMS Board
Added emulation of the LoTech 2MB EMS Card
This card can be added to any machine configuration via the lotech_ems overlay. You can specify the window segment
and IO base address. However, these values must match one of the values supported by the real hardware or the driver
won't work with it.
Game Port and Joystick
Added emulation of the IBM game port card, and basic keyboard-based joystick emulation. There is a new keyboard
hotkey (JoyToggle) to turn this on and off (provisionally defined as Ctrl-F9), as well as configurable
joystick_keys in the configuration you can use to define what keys control the joystick.
PCJr and Tandy 1000 machines will have a game port installed automatically. You can add a game port to any PC or XT
configuration via the game_port overlay.
Two two-button, two-axis joysticks are assumed to be connected when you specify a game port.
Different joystick configurations may be supported in the future.
PCJr Cartridge Slots
Added support in the core, frontend and GUI for PCJr cartridges in JRipCart format. Inserting or removing a cart
will reboot the machine. You will only see the cartridge slots when using the PCJr machine.
Frontend Bug Fixes / Improvements
Added a new resource type 'cartridge' and menu interface to browse and select PCJr Cartridges.
Core Bug Fixes / Improvements
SERIAL: Fixed many issues in MartyPC's 8250 UART emulation. PCjr now boots without error code 'D' and Checkit2 serial
diagnostics also pass.
BUS: Implemented a terminal_port configuration option under [machine] in the main configuration. Writes to this
port will be printed to the host's terminal.
MC6845: Fixed an issue preventing entering vertical total adjust period if vertical total was 127. Fixes some Hercules
display issues.
HERCULES: Increased the size of the Hercules' display field to accomodate some CGA emulators that drive the MDA
monitor slightly out of sync (Fixes BBSIMCGA)
CGA: Added CGA's external mode register to debug output
MACHINE: Added a facility to record disassembly listings from running code. The output filename is set by
disassembly_file under [machine] in the main configuration.
Basically, this feature saves instruction disassembly to a hash table by CS:IP. Modification of code segments will
override previous disassembly, so it is most useful to toggle this feature on and off for specified periods.
Debugger Bug Fixes / Improvements
Serial Status window: Displays serial port registers and statistics.
IO Status Window
Added a 'reset' button to reset all the port counters.
Added the last read byte value for each port
Fixed panic/crash when resetting machine with the IO Stats window open and scrolled.
Distribution Changes
Added a SvarDOS-based MartyPC boot diskette to media/floppies/boot.
This disk will load the LoTech EMS driver and CTmouse driver.
Moved FreeDOS to media/floppies/DOS
Added SvarDOS build 20240201 diskettes to media/floppies/DOS
Added ctmouse v1.91 (last working version for Non-VGA) to media/floppies/utilties/mouse
Added LoTech 2MB EMS card utilities to media/utilities/EMS
Added JOYCALIB to media/utilities/joystick
Updated GLaBIOS 0.2.6 ROMS for a bugfix when int 10h vector is overridden
Dependency Updates
Set rustc minimum version to 1.76
Update egui to 0.27.2
Update wgpu to 0.19.4
