Can I play/edit a Toolkit version 2 game with Toolkit version 3?
Yes—although you may have to edit some parts of your programs and remake some of your game files. To start, copy your game files from your Toolkit2\Game folder to the Toolkit3\Game and the main game file from Toolkit2\Main to Toolkit3\Main—make sure you keep a copy of the old files in case anything goes wrong. As a precaution, open your game files in the TK3 editor and resave them to convert their format to TK3; specifically for character, item, board and animation files (tiles and programs do not require conversion). You may find in the case of characters and items you need to reconstruct the file completely. With your programs, you will find that some commands have been removed or upgraded for TK3—watch for the debugger when testing them for information on upgrading.
