v1.9

This release fixes bugs when building ROMs, adds animation hitbox exporting to BG2Img, and introduces a new tool: PatchGen!
If you feed a project file to PatchGen, it will create a .sapatch file, which you can then use in AdvanceBuild in place of a project file to generate a modified ROM. The .sapatch file is simply a ZIP archive containing only the files that were modified from your project, plus some necessary metadata, which means they're safe to distribute and fairly small.

For people who only want to play mods distributed in patch format, I have included an archive containing only AdvanceBuild.

Note for modders: if you want to make patches, you will need to extract a new project for each game and copy the .saproj file into your old projects, as the patch format required me to add size information for each file to the project.
