Even though you have given up (apparently), I'll give you a scattergun of some info that might eventually be useful.
According to http://software.opensuse.org/search?...ude_debug=true
Intellivision emulator. Put required ROMs (exec.bin and grom.bin) in /usr/share/bliss. See /usr/share/doc/packages/bliss/Readme for more details.
So, obviously, there is no point unless you have the appropriate rom images available. The other point is that if you have an internet connection, Bliss itself is a simple install (that's not necessarily the same as simple to configure or simple to use...but you probably know that). It is in a repo, and once you have added the emulator repo, its a one click. Assuming that all this doesn't work, tou would have to download the file to an appropriate directory on your hard disk (using your mobile phone or some other method....hence or otherwise as they used to say). You've got to get the program somehow, or you don't have the program.
Then go into 'install and remove software', define the directory that you used in the previous stage (...hence or otherwise...) as a repository, and yast will then let you install from that directory with a click.
There is a disadvantage in using this method to get around the lack of internet connectivity - dependencies. Normally, if a program needs libraries to function, the installer will sort it out for you; in this case, the installer can't get the libraries, if it hasn't already got them, so you have to deal with this by the same method used in the previous stage, which is admittedly a bit of a pain. If you could get internet connectivity, eg, via your phone, this would be easier...but that may not be an option.
See your files? To do this from a GUI, you need a file browser, and there are many of them. Konqueror, Dolphin, Thunar, Krusader and others.
The other thing is that the partition that your files are on has to be mounted for the files to be visible; in order to see which partitions are mounted, you should type in a terminal (Konsole, Yakuake, Gnome terminal, LXterminal, etc) and type;
You may see some things that you don't expect (windows partitions, tmpfs, debugfs, etc) but you should see the highest directory of each of the trees in which you have data. It would be difficult for us to say exactly what you should see, because it is slightly dependant on what you asked for when you installed the system, but you'll probably see '/' and '/home' (each of the 'real' partitions will probably be on a partition denominated /dev/sdax, where x is an integer, and the type will probably be ext4, or similar).
I'd guess that you have put any of your own files under /home/username (where username is your username). From a terminal, you can get there by typing
and ls will list any files that are in that directory, and you can 'cd' to another directory within that directory by
(assuming 'otherdirectory' exists, and is in the directory that you are in at the time that you issue that command)
