[HELP] PSB files [image_body.bin, image_info.psb.m][Nitendo Switch]

Post by amVspR »

Hi there, I need help extracting the psb files from a Nintendo Switch game.
Game name: B-Project: Ryuusei * Fantasia
Samples of the PSB files (textures): https://mega.nz/file/8lBWBBYb#nrKsqo_a9 ... lPk1_Ku2jo
Other related files (image_info.psb.m; scenario_info.psb.m; etc.): https://mega.nz/file/t5wxGLzY#QcXLydgaq ... 490jEHT0QI
If any additional file is needed, please let me know.

You can use FreeMote tools for such games (key for this one is "123abcd21asff"). For more info see similar topics (example).

For comparison, modified exm2lib from the attachment can also extract stuff from this game, but result images will be incorrect.

Thank you so much. I worked like a charm! How did you figure out the key? (If you don't mind me asking)
