Actually Sashimi by itself doesn't work, before running "Sashimi", you have to run "Snoopy" which is for the settingsim by Sashimi, then you can iconify Snoopy, done that once you run Sashimi it will open a Shell and it will work like Snoopdos.
To be honest I am not familiar with these tools either, I discovered them in my time of need, there is also a third debugging tool in the "System/Debug" folder it is called "Bifteck", I don't know how it works.
The icons to start "Sashimi" and ""Snoopy"" you also find them on the bar on Amistart !
