ah yes.
well, this guy compiled it himself from the sources that i linked to, it's not an "official" version...

if you already have that file, it's probably the executable itself. i don't know if it'll run just like that, but you can try:

copy it to /home/user or /opt (anywhere but MyDocs is good, because MyDocs is a VFAT partition and doesn't support the next step that is needed)
then make it executable
then you can (or cannot, as i said i have no idea if it'll work) run it using "/opt/<drnoksnes_filename>"
