"This is probably the best 8-bit Commodore emulator around. Installing from software manager leave you a little in the dark as to what you have to do as far as installing the roms required, so perhaps that's why the negative reviews. In anycase, you want to find the installation (/usr/lib/vice probably) and in there are folders for each of the machines. You'll want to put files called 'chargen', 'kernal' and 'basic' in the C64 folder before x64 will run. Similar for rest of them, but that should get you started. Good luck!!"
"Took me a little playing around to figure it out, but it seems to work well. Couple things I'de like to have seen... when shrinking the window, it remember the split between graph and sensor list, so when you expand back out again it's not just the graph. (Maybe an option to always show grid and sensors so you can't shrink it down to nothing....) And start logging maybe the first sensor in the list on startup so you get an idea of what's going on immediately. Good job!"
"Exits on startup... not sure what's going on."
"Doesn't seem to work with 18.3 either. Unable to select type of account to add."
