==Block header size==
This was made with the goal of identifying the last value at the block headers, the file is well formed but the value in red has been modifyed, originally was a 0x10 and has been changed to 0x20

At the time the area at 0xA0 is loaded (block id 0x00FF intended to store the '''file_info''') the real header size is 0x10 but the value changed takes the next 0x10 bytes as part of the header... so it starts reading the '''file_info''' at offset 0xC0
This is how it looks when this file is converted GIM to GIS, note the strings at the bottom how has been cropped

Also, the length of the value marked in red is confirmed to be 4 bytes, it can be seen how the bytes are swapped when using the setting '''format_endian''' = little/big
