Bottlenose Development Thread

[qashto]

Hello dolphin devs! I have a quick question. How do I get the game id from a game .iso, .gcz, or .wad without using the dolphin UI?

I'm asking because I'm working on a front end called bottlenose for dolphin and other emulators.

https://github.com/quinton-ashley/bottlenose

Currently it matches games to the gamestdb wii games database via fuzzy search but it doesn't work well if people don't name their games using the official titles as the file name. If I could do it purely in node.js or command line dolphin that would be ideal.

For ISO files: Read the first four or six bytes, depending on what you want.

For WAD files: Calculate the offset of the TMD, then add 0x190 to get the offset of the four-character game ID. If you want the publisher ID (equivalent to the fifth and sixth bytes of an ISO file), add 0x198 instead of 0x190.

For GCZ, WBFS and other container formats: I think you would need to implement support for the whole container format. Once that is done, treat it as an ISO file. Code is available at https://github.com/dolphin-emu/dolphin/tree/master/Source/Core/DiscIO (the files with names ending in Blob).

If you don't want to implement all of this yourself, wit can probably do it for you.

Thanks!  I'll look into using the wit tool!

Have you used the wit tool before?  I can't figure out if it's broken or I'm just using it wrong.  I tried on macOS and Windows, still get this error.  The game loads fine in dolphin.

If I use the folder instead I get the same error.  I got the command filetype to work but not list or many others.
