I just uploaded Version 1222, which has been updated to be backwards compatible with saves. To update an older save, copy GameState.mmf from the 1101 game directory to the 1222 game directory (in the same folders as the exe files), then start the game, then close it once it's up and running. This will automatically overwrite the 1222 folder's GameState.mmf to the 1222 version of your older 1101 save file. PLEASE create a backup of the original in the 1101 folder as well, just in case. Let me know how it works out if you give it a shot. Also, I'm still working on UI improvements, and do plan on removing the 'Stats' button from the main window - I might replace it with an Upgrade Quick-Buy button...
