Numsgil:
Newer sysvars are generally backwards compatible, so as long as you have the newest, your version will work like it always did.

I've created a simulation emporium for zipping and saving simulations/settings.

what does 'generally' compatible mean? ;)
well ... that hasn't been my experience.
it seems to make a difference ... but it's difficult to tell for sure as
I get so many errors that I can't really do any real troubleshooting
or isolation of any one problem.
but things appears to happen differently with different sysvars.
now that I can actually run a few different versions ...
perhaps I can come up with a simple test sim to check it out.
and one must also remember to designate/force a 'seed' ...
to eliminate that as one of the variables.

great.

Numsgil:
Gnerally compatible means that as long as the number of entries in sysvars2.21.text is <= 200 they're 100% backwards compatible.

I don't think we're there yet, but we're awefully close.

PurpleYouko:
Sysvars 2.21 was created because sysvars.txt couldn't get any bigger without making it impossible for the older versions of the program to load it. They could only hold 100 sysvar labels internally.

When we finally exceed 200 then we will introduce a new sysvars file and tell the newer programs to read from it instead. Until we reach that point just use the newest sysvars file that you have and all versions will run happily with it.

All the sysvars does is to provide the program with a list of labels for memory locations so that it can decipher bot DNA code. Ironicaly if you run a very old version of DB with a very new sysvars and a very new bot DNA file, it will see all the DNA values as labels in the DNA window but a lot of them won't actually do anything in the program.
