[Atari] Fujisan 2.0.2 16/04/2026

Fujisan 2.0.2 16/04/2026

This release is a significant stability update addressing numerous crashes and threading issues that occurred during emulator shutdown, restart, debugger usage, audio handling, paste operations, and NetSIO configuration changes.

Hightlights

• Updated toolbar, to include INSERT and CLEAR buttons
• Fixed problem pasting text into the emulator where it would remove duplicated characters (e.g. PEEK would be PEK after pasting it)
• Fixed Full Screen toggle feature - On Linux and Windows one couldn't go back from Full Screen
• Renamed artifacts to make easier to find your version to download
• Added test suite to improve quality for each release.
• Fixed problem where holding the Shift key and typing wouldn't produce the upper case character on screen

Fujisan 2.0.1 12/04/2026

New Features

• Added CLEAR key via menu System -> Special Keys or F8 (UI button will be added in the future)

Bug fixes and improvements

• Created separated thread to handle the emulator windows - This will make any UI action to not block the emulation and vice-versa
• Fujinet slowness/hang problem "reduced" - Although it can still happen, the chance to occur was reduced by reducing the HSIO speed by default.
• Windows/Linux - Often on Windows and Linux, the users need to click the emulation window to be able to interact with it, after Fujisan UI is used (for example, when clicking the Fujinet widget (R)eset button). In this version, the focus returns automatically to the emulation screen when such UI actions are performed, improving the user experience.
• Improved speed when loading XEX files via Visual Studio Code Fastbasic Debugger extension

Fujisan 2.0.0 05/04/2026

New features / improvements

• FujiNet-PC on Windows – Built-in FujiNet support extended to Windows (startup, reset, NetSIO stubs/polling, bundling, and related fixes). Note: If you find anything wrong, please use the GH issues to report the bug
• FujiNet UI – Status widget with reset/swap (and related layout/tab tweaks); drive UI integration with FujiNet-PC web API; drive LED activity; printer integration improvements.
• NetSIO / HSIO – HSIO divisor range and reliability work; default HSIO config set for more reliable operation; progressive slowdown and race fixes; FIFO flush, Windows recv timeout, and service fixes; FujiNet-PC restart resets NetSIO client state; upstream NetSIO patch refresh. Note: This is not perfect yet so if you still see the slowness/hanging while loading CONFIG, reduce the HSIO value in the Fujinet UI (localhost:8000)

Bug fixes

• Fixed problem saving some of the settings (e.g. external ROM)
• Fixed sound quality problem in all platforms
• Fixed speed toggle that wasn't changing to max speed
• FujiNet-PC cold boot / restart races and force-kill + restart path.
• FujiNet-PC startup/crash issues on Windows; OpenSSL bundling/notarization-type issues on macOS for local builds.

Fujisan 1.1.8 11/03/2026

New Features

• Built-in Fastbasic compiler - Enable via Settings -> Emulator -> Show Fastbasic build panel - In the panel, simply select the folder where the .BAS files are and you can build and run the XEX file.

Bug fixes

• Fixed audio problem with the Windows.

Fujisan 1.1.7 5/03/2026

Bug fixes

• Include fujinet with fix bug where it would crash if using long paths for SD Card (FujiNetWIFI/fujinet-firmware#1204)
• Fixed H: drive support which wasn't working in 1.1.6

New features

Note: Preparing for upcoming Fujisan support in VSCode Fastbasic debugger (EricCarrGH/vscode-fastbasic-debugger#1)

• TCP commands to start and stop Fujinet
• Document and manage FujiNet cold-start behavior via a new patch (0009) that replaces netsio_cold_reset() with netsio_warm_reset() inside Atari800_Coldstart(), with a manual fallback in apply-patches.sh.
• Move "Hide FujiNet-PC logs" checkbox from Emulator tab to FujiNet tab (Logs group)
• Add "Load CONFIG application on boot" checkbox in FujiNet tab. You can now disable it to get a faster boot when using Fujinet with a known applicatiion in D1 slot by default.

Fujisan 1.1.6 2/03/2026

New features

• OPTION key when using with Fujinet will behave like the real hardware. If you press the OPTION key, it will reboot using the mounted image. If you press and hold the OPTION key (for about 5 secs), it will boot the image but won't load BASIC, leaving more space for the application loading. Note: When not using fujinet, the settings to enable/disable BASIC will be used instead.

Bug fixes

• Fix problem that Fujisan would crash when trying to save any profile
• Fix problem when using the --build-fujinet-pc flag where the data folder was missing if not already copied into fujisan's folder. This only happens when trying to build it from a fresh clone.
• Update SHA reference for atari800 to include important changes that makes fujinet boot more reliable
• Adjusted Media Configuration UI glitches
• Fix cross-platform Settings dialog rendering with truncate UI elements
• Fix tab key being consumed by QT UI instead of passing it to the emulator core

Fujisan 1.1.5 26/02/2026

Frontend Fujisan dla Atari800

New Features

• Keyboard joystick presets: Joystick keyboard emulation now lets you select presets to customize which keys are used for each joystick, with built-in support for NumPad, Arrow keys, and WASD layouts.
• Linux FujiNet-PC updated: Updated fujinet-pc with the latest changes, including important fixes while handling JSON data.

Bug Fixes

• Tab key captured by Fujisan instead of emulator: Tab (and Shift+Tab) keypresses were being intercepted by Fujisan's UI focus system and never sent to the emulated Atari. This prevented using Tab for navigation inside Atari programs — most notably the FujiNet configuration menu. In some cases the stray focus changes inadvertently altered Fujisan's own settings. Fixed by intercepting the key at the Qt event level before focus navigation can grab it.
• XEX loading via TCP API broken when FujiNet/NetSIO is active: When FujiNet was enabled, loading XEX files through the TCP API (e.g. from the fastbasic-debugger VSCode extension) failed because D1: commands were unconditionally routed to FujiNet-PC. BINLOAD now takes priority during XEX load and hands control back to NetSIO afterwards.
• macOS FujiNet-PC OpenSSL signing error: Fixed a code-signing error ("Team ID mismatch") that prevented FujiNet-PC from launching on macOS when built without an Apple Developer certificate. OpenSSL dylibs are now bundled and re-signed as part of the app.

Improvements

• XEX loading is faster when FujiNet is active — the emulator core now reads XEX data in chunks instead of byte-by-byte, reducing I/O overhead during load.
