Today I helped someone get a tricky set of files opened with Abiathar. The graphics failed to load, even when using the graphics files specified by the patch file and the correct EGADICT. Some debugging revealed that the search for the next real EGAHEAD entry (to calculate the length of the chunk) was reaching the end of the the marks array without finding a non-placeholder entry. Looking at the EGAHEAD in a hex editor, I'm confused as to why that is, since there are real entries all the way to the end of the file. Perhaps there's something wrong with the optimization intended to reduce the number of chunk decompressions - I will need to investigate further.
Reducing the reported number of foreground tiles made the load work. I don't know whether the game is able to access those last two, but if it is, that's definitely a FleexCore2 problem. I'll have to check.
