After some years I got the idea to port the old levels made in TGF to the new engine and because I'm a little "lazy" I didn't copy the levels by hand, but thought that it would be quite nice to write a tool that does it for me.
So I started to reverse engineer the file format of TGF and I made a tool called Clickteam Extractor.
This tool unpacks all game files and displays images from Klik 'n' Play to Multimedia Fusion 2. It also has a Level Viewer for TGF/CnC/MMF Express games that can also save complete level maps.
You'll be surprised what these gam-file can contain. (e.g. unused music)
Now the fun part: something to play
I also wrote a converter to convert TGF levels to my custom Sonic game engine and I converted this game.
You can download the improved version here.
After converting it I just did the these things:
- adding the original music
- make a pixel-perfect copy of the original title screen (without the play-button)
Note: The game has very many secrets. e.g. an options screen
