What about support for .pack files?
You said that it has compatibility settings for Last Window, but I'm not noticing any. Almost all the files in the game are .pack files, including for the graphics and text. In fact, on large file, Char_Steve.pack is very interesting, because there was no character in the game named Steve. So if the graphics of that file are extracted, it would be a huge deal to any Kyle Hyde fan! I know that there were full animations made of characters that were never used. Some of that may lie in this game.
