FujiNet-PC Launcher is bundled together with Fujinet-PC binaries, NetSIO hub and custom device file for Altirra into one FujiNet-PC bundle. Python runtime and necessary libraries are included too.
Download the bundle.
Extract the files. Create or use the directory of your choice for extracted files, e.g. C:\Atari\FujiNet.
For your convenience create a shortcut to launcher.exe and move it to Desktop (or some other place of your choice). Shortcut can be given some nicer name, e.g FujiNet.
Use the shortcut to run FujiNet-PC Launcher.
When started for the first time, the OS may ask for security confirmation.
The Launcher will run FujiNet-PC and NetSIO hub programs in background. The leftmost LED (white) indicates that FujiNet-PC is running. Next LED (blue one) indicates that NetSIO hub is running. The LED on the right (amber) will be active when the SIO communication occurs.
Similar to real FujiNet use buttons for some basic actions. Right click empty area to open pop-up menu with few more options.
Finally, the two pieces, Altirra and FujiNet, must be connected. For this custom device have to be plugged in to Altirra.
In Altirra, navigate to menu System > Configure System... In Configure System window navigate to Peripherals > Devices and Add custom device. Use ... button to navigate to emulator\Altirra and select netsio.atdevice file. Once added, the device will be listed as NetSIO - SIO over network custom device.
To allow emulated Atari boot from from FujiNet via custom device the Fast boot acceleration feature must be disabled.
To boot from FujiNet (acting as D1:), similar to real Atari, there cannot be multiple D1: drives attached to SIO bus. Detach other D1: if any.
To simulate power cycle of both Atari and FujiNet one can use Cold Reset. To "power cycle" Atari only use Cold Reset (Computer Only).
