It's based on the Slacko distro of Puppy Linux with a LXDE desktop interface. It comes with several pre-loaded packages, so it's a very functional environment from the start. Takes about a minute to load. I set a 4gig savefile, so it takes a while to close down while the memory is being written to the USB. I'm pretty impressed, except that...On about my 5th boot it failed to launch the desktop and black-screened. It's supposed to revert to a setup screen on my next reboot but it doesn't. It looks like I can get to a command line with a 'nox' argument but I'm not sure what to do once I get there.
Simplicity is reported to have Wine pre-installed, but I can't figure out how to invoke it. The Package Manager doesn't have it listed as something I can uninstall so I'm guessing that it's incorporated into the OS somehow. Anyway, clicking on a Windows/DOS EXE asks me what I want to use to run it. Where do I go from here?
