File Format Reverse Engineering 3 - Templating with 010

In this video we'll start building out an 010 template to help document our knowledge of the file format. This method is extremely helpful as it forces us to consider the size and relationships between elements in the file. It's also a great way to help expose patterns we might otherwise not see.

Awesome video! The third byte of the file "0x00" looks like the number of the first card which might sort out the alignment

All your videos from 1 to 4 are very helpful. Thank you so much. In the video, the game reads and writes file multiple times with offsets and data lengths. However, in some cases (that I was personally trying to reverse) the game reads the whole file at once. Is there any suggestion on reverse engineering these type of software? Again, thank you for your video.
