A "rise from the grave" post to say that my very simple GFA shell - purely for saved game editor creation, complete as a working example for Legend Of The Sword, is now on my website.

The original plan was to get everyone of my other saved game editors updated to use the new shell above (as it now uses SNDH music file replay), but that's probably not going to happen this year (well, not before the summer time anyway).
So grab the code, for those that are interested in creating small and easy to create saved game editor tools

My main site:

I develop a free Word (for Windows) add-in that's available for Word 2007 upwards. It's a fix-it toolbox that will allow power Word users to fix document errors. You can find it at:
