On a freshly installed Raspberry PI, you can install FUSE as an emulator thats autostarting right from the start.
first make your installation up to date and start a terminal and enter:
sudo apt-get update && sudo apt-get upgrade
sudo aptitude install fuse-emulator-sdl spectrum-roms fuse-emulator-utils
You could test Fuse now:
fuse-sdl
Fuse should start now.
To leave Fuse, press F1 File eXit Yes ENTER
On the Raspberry Pi3 running Raspbian Stretch this is what I did to make Fuse autostart:
First make a script file that starts Fuse:
nano /home/pi/.config/lxsession/LXDE-pi/fuse.shAnd enter:
#!/bin/bash
/usr/bin/fuse-sdlAnd save the file (CTRL X)
Make it executable
chmod +x /home/pi/.config/lxsession/LXDE-pi/fuse.shNow edit the autostart file
nano /home/pi/.config/lxsession/LXDE-pi/autostartand add this at the end of the file:@./fuse.shsave & reboot
If all works OK, you could make Fuse running full screen:
