CasioEmuMsvc: Emulator and devkit for Casio nX-U8/100 and nX-U16/100 MCU series

Developer telecomadm1145 released CasioEmuMsvc, an open-source emulator and development kit for Casio's nX-U8/100 and nX-U16/100 microcontroller series, offering full emulation of both MCUs alongside a debugger, disassembler and hex editor. The tool includes a snapshot system with branching save-states and screen previews, a plugin API supporting MCP (AI-driven), Python, Cw2tools and custom plugins, and builds for Windows (MSVC), macOS, Linux (CMake/Ninja) and Android (Gradle/NDK). The project's README notes that the ad-hoc-signed macOS build is quarantined by Gatekeeper on first launch and requires running "xattr -cr /path/to/CasioEmuMsvc.app" in Terminal to open.

Important

macOS Usage

Because the macOS app is built and uses an ad-hoc signature, macOS Gatekeeper will quarantine the app and may display a "Launch failed" or "App is damaged" error upon first launch.

To bypass this protection, after extracting the file, open your Terminal and run the following command to clear the quarantine flag:

xattr -cr /path/to/CasioEmuMsvc.app

(Replace /path/to/CasioEmuMsvc.app with the actual path to your extracted app. You can type xattr -cr and drag the App into the Terminal window). After running this command, you can simply double-click the app to open it normally.
