Sometime in early 2022, I tried to use Tinke to view files inside Nettou! Powerful Koushien and Atsumare! Pawapuro Kun no DS Koushien. I couldn't do anything however because I couldn't figure out how to open these .BMB files, it just brought up a "NOTHING TO DO" error message when I tried opening it. I even exacted one of the files and converted it to .BMP and tried opening it with IrfanView but that just brought up a "Broken header" message. There was very little documentation on .BMB at the time I tried doing this, so I was wondering if anyone here could help me figure out how this file format works, or if there is an alternative to Tinke for viewing these kinds of files.
