Good evening everyone !
After many unsuccessful attempts, I changed emulators because FS-UAE really has too many bugs !!!
A simple example FS-UAE is unable to recognize the plugin
qemu-uae.dll !!! In addition it is absolutely slow !!!
In short, I installed WinUAE which is a marvel in comparison & I followed this excellent tutorial
here.
Everything works even the network I am very happy !
Greetings !
