I am looking for help in extracting the script for two games.
The first is sisters ~Natsu no Saigo no Hi. According to VNDB this is using a game engine called ISM. I used GARbro to look at the .isa data files. Within the data file there are .ism files which I am assuming contain the script. These are binary files from what I can find, but I am not sure how to decrypt/open them to begin translating.
The second game is Kanojo x Kanojo x Kanojo. This game uses the AST engine according to VNDB. The data files for this are named dat01, dat02, etc... with no extension. Viewing dat01 with GARbro shows all of the script files. These are in .adv and when I extract them they are easily edited as straight text files. The problem I am having is being able to repack the dat01 file without an extension.
So I guess what I am looking for is any tools anyone has that can be used to unpack and repack AST and/or ISM game files. Anything helps.
