This topic is only for the few users who know the old unix tool "file" In the last weeks I have played with the magic file. My plan was, that the command "file" will detect Wii ISO, WBFS, WDF and WIA file types and gives some infos about them Example: Code: # file * mkdd.iso: GameCube ISO image 'GM4P01' Mario Kart Double Dash! wch.iso: Wii ISO image 'RTYP01' Wii Chess 4-games.wbfs: WBFS v1, hss 512, wss 8M, multi disc archive mkdd.wbfs: WBFS v1, hss 512, wss 2M, GC 'GM4P01' Mario Kart Double Dash! wch.wbfs: WBFS v1, hss 512, wss 2M, Wii 'RTYP01' Wii Chess mkdd.wdf: WDF v1, v-size 1459978240, 416 chunks, GC 'GM4P01' Mario Kart Double Dash! wch.wdf: WDF v1, v-size 4699979776, 27 chunks, Wii 'RTYP01' Wii Chess mkdd.wia: WIA v1.00 LZMA.5@20, v-size 1459978240, GC 'GM4P01' Mario Kart Double Dash! wch.wia: WIA v1.00 LZMA.5@20, v-size 4699979776, Wii 'RTYP01' Wii Chess 'file' will now print geometric data and also image ID and title. And here is the magic source: http://wit.wiimm.de/download/magic.txt How to (linux): Download by extension. Edit the file /etc/magic: a) Remove old versions of my extension. b) Append my extension at the very end of the file. And now "file" should detect the image types because of analyzing the file content.
