This is a little C# Tool to create MBIF files based on normal images.
Either drag a single image or a whole format into the executable and it will ask you to enter the position offset.
(You can just enter 0 for the offsets if you dont want it to be centered)
After that it should create a file or a folder with the converted mbif files.
The format is a very simple bitmap-ish format.
It has a small header and then the raw image data as 32 bit ARGB.
The file is structured like this:
Byte 00-03 - Image Width (int32)
Byte 04-07 - Image Height (int32)
Byte 08-13 - Image X Offset (int32)
Byte 12-15 - Image Y Offset (int32)
Byte 16-23 - Image Data Size (uint64)
Byte 24-.. - Image Data
