STARTPOS Editors
http://www.4shared.com/zip/1Ipd5Wzjba/esf_editor.html?
Above is a link to a zip I made with two Starpos editors. One is relatively easy to use, and allows you to edit the turns per year of saved games and startpos.esf files. The other is ESfeditor 1.4.8, and it is a more advanced system. But it will allow you to edit Startpos files the same as windows users, so you can file instructions that already exist out their on the webbyweb.
It includes a file wrapper. What you do is right click on the .exe you want to use, and open with -> file wrapper
TROM Startpos.esf - 4 turns per year

Here is a link to a TROM startpos.esf which I edited to 4 turns per year. The new year starts in winter, because that in my experience the new year does not herald springtime, it happens in the dead of winter.
