So here is the decoder app at last, download the file and remove the .ttf so it ends with .zip and extract. Follow the readme and there you go!
From my testing it all seems fine apart from there could be an issue with 1 AE cam file not converting properly (STP01C11.CAM). Or it could be this is how the file is supposed to look.
Don't bother asking about replacing CAM images in AE because its NOT going to happen.
Edit: Oh BTW this will also convert pretty fast since its mulit threaded, it took about 2mins to convert all AE and AO files on my laptop
Since this uses Qt it builds and runs on Linux (which is what I developed it on) but I won't be releasing any Linux versions, I tested it under wine and it appeared to function correctly.
