today I found a backup CD and guess what was on it - the source code to the EMI Resource Viewer which I thougt was lost for good in a HD accident.
Now it can play Wvc files and save them as Wave files; and it can decompile the Lua scripts into very readable Lua code (thanks to Igor Skochinsky who gave me the source code to this). It is based on the stand-alone tool which does the same task.
Also thanks to james_isaac here on the board who told me you can't open files straight off the CD (it worked for me once but today it didn't) so I also fixed this.
