We are team of few Delphi developers who have been using VSS since years (I know it\'s a pity), but we don\'t use any of the advanced features of VCS, so it was working fine
Just use SVN and an excellent TortoiseSVN client which integrates with the Windows Explorer.
P.S. Found this question: What is the best set of tools to develop Win32 Delphi applications? and this Delphi IDE/TortoiseSVN integration tools in one of the answers: http://delphiaddinfortortoisesvn.tigris.org/
