Gregory's ServerBeen doing a fun new reverse engineering project: Figuring out the file formats of the 1999 Windows/PS1 game Attack of the Saucerman. It's the first time I'm doing this on a 3D game. I'm now at a point where I can partially display the levels, and extract most of the assets:

I already made an attempt many many years ago, but was only armed with a hex editor at the time and couldn't make any sense of the data. (cont.)
This time, I started by disassembling the EXE using Ida, and was able to identify the overall structure of the files. Once I knew how the level files are laid out, I was then able to make targeted changes and observe the result when running the game, which helped fill in most of the gaps, alongside more disassembly. What also helped a ton was a good number of debug log strings left in the code by the devs. (cont.)
