I guess it will no problem if the game does not extract into .bin + multiple .api tracks. Then probably those other sound data is lost. But if it will just extract into 1x .bin and nothing else then the .cue will not a problem. The ones from the database also just link to this 1 data so auto generation would be ok. But now I see Dead Or Alive, Rayman 2, Tombraider, Resident Evil 2, Castlevania have multiple .api and so I just downloaded that stuff from Github.#
It might be obvious for people who use that website often what to do with those files. But by randomly clicking I would absolutely never realize how to get this .cue file. At the end just grabbed it from browser with JDownloader 2.
