Sure, here it goes:
Deprecation raiseWarning: false.
Gofer new
squeaksource: 'MetacelloRepository';
package: 'ConfigurationOfCog';
load.
((Smalltalk at: #ConfigurationOfCog) project latestVersion) load.
The version of ConfigurationOfCog loaded was 3.3.

I'm using VMMaker-oscog-IgorStasenko.123.
I've checked updating to the latest version, VMMaker-oscog-dtl.125, and
those two seems to be fixed.

Done! :)
I've shared a file,
http://dl.dropbox.com/u/45558068/Pharo-1.2.1.cog-ChangesSoFarToMakeSimulatorWork-images.7z,
containing two images:
- Pharo-1.2.1.cog.image: this is your original image, with all the changes
I commented, and a workspace with all the needed code to initialize and run
the simulator.
- simulated.image: a snapshot Pharo-1.2.1.cog.image to be simulated
Also, I managed to get the PharoDebug.log from simulated.image (I think) and
not from Pharo-1.2.1.cog.image describing the "Error:
setGCBiasToGrowGCLimit: failed" error.
That file, named PharoDebug - setGCBiasToGrowGCLimit - failed.log, can also
be found on the .7z file.
