As far as I know having a working simulator working requires quite some
effort. At least, with a Pharo image. A couple of months ago (maybe a
couple of years) there was another Argentinian which finally made the
simulator to work with Pharo 2.0. You may want to get in touch with Nicolás
For the developments I did I always used the "generation.image" and then
use the VM I built. I never used the simulator for real.

Well...it depends on what you need to write exactly. Slang is quite limited
since it must be automagically translated to C. So you must be careful in
the "smalltalk" code you write with SLANG. To know more or less what you
are able to write in SLANG you could take a look to
#initializeCTranslationDictionary (at least this was some years ago).
BTW, you may want to read this: https://marianopeck.wordpress.com/tag/slang/
