I’ve had chance to test the patcher more thoroughly and sorted out a few issues:-

• There were problems with Ultima 4 and both Underworlds when the games weren’t installed in the usual directories. It would ask you to choose the directory but then not open the form for that game. This is now fixed.
• I’ve tidied up the player transfer substantially for Ultima 5. It would previously never find the correct Ultima 4 directory automatically unless you happened to have the same username as me. To make this simpler, you now just need to specify where you installed Ultima 4 and it does the searching in virtualstore automatically if required. It probably isn’t needed but I’ve made the same changes for Ultima 6 also.
• I’ve added links to the websites of the various patches, where I could find them.
• It shouldn’t crash any more if expected files are missing.
• I’ve added an about page + a version number. I’ve nominally called this version 1.0.

To the best of my knowledge it’s working correctly now. It’s still ugly but I’ll leave it as is unless anyone runs into problems with it, or has good ideas for things I should change. If GOG releases any more Ultima’s, I’ll add them in as well. I think there is just the one more release due in this batch from EA. We’ve had far more Ultima games than I expected already but I’ve still got some hope we might see the Worlds Of Ultima games next week.
