Avid

I suppose that a port will proceed by converting all the data files, and then porting the sources as appropriate. To this end, I am describing the various data file formats here.

Most of the Avvy file formats have filenames of the form "[type][number].AVD". "AVD" is pronounced "avid", and stands for "Avvy data". The types are listed below. A few file formats do not use the .AVD extension, but they are similar enough to be discussed here anyway.

If you write code to decompile an Avid format into an intermediate form such as XML, I'd like to include the decompiled files in this repository.

See also Avx, which is another file extension for something else.

• PLACE*.AVD, SCREEN*.AVD, CHUNK*.AVD, ALSO*.AVD: see Rooms
• SPRITE*.AVD: see Sprites
• AVALOT.SEZ and *.RAW: see Sez
• *.ASG: saved games; see Edna

(More to come later)
