Have a chat with Joshtek on the Clickteam Forums, he may have some apps to help you.
I worked with him for a time on the .GAM file format (we were trying to build a spec). I quit after some time, but i think he continued his research and got quite a bit further. He actually managed to make quite a detailed .gam editor as I recall - not sure how far he got with PAPPs (Protected games).
It could be interesting for someone with a Hex Editor and some time to try copying the game chunks from a PAPP to a GAPP (unprotected game) and see what happens.
I'd personally have been really fascinated to see how Events are stored in GAPPS and PAPPS, since we never really looked into it. Potentially, you could build an app which scans GAM files and returns a text version of the event list.
You may have to make do with simply ripping what you can. Wavs are rippable as shown above, and music is extracted to the temp folder in-game. Look in the temp folder, and search for .mid files whilst the music is playing in the game. You'll find the MIDI has been extracted by TGF, because TGF's runtime can't play music internally. This is why you sometimes get a lag when starting a MIDI.
I don't remember much about the Image Bank in a PAPP. I think it was kind of encrypted, but more like Run Length Encoding (RLE) which isn't that hard. It may be simpler to print-screen the sprites.
Well I have been looking there while game playing and i dont see any midis ..............I have been trying to figure out a way to get music from worm wars III just the music not the graphics.lol
Is it really worth it to go onto the battlefield? I GOT A CUSTOM RATING SEE???
