@Tgames: Since Gildor already answered in the game topic, why it can be problematic to implement support for this format, I can also confirm that I will not support it for now, because steam version of the game is using usual format and contents are the same in both versions (reference for others
It's a bit unrelated, but I noticed that current bms script doesn't support proper extraction of raw data from modern paks (in most cases it can be extracted without index, but also without proper filenames and extensions), especially if dynamic padding is used. It's about time to make something with this.
@einherjar007: Yes, on rin forum first one or two posts will be pre-moderated - it seems mod staff are just busy at the moment. Back on topic, I'm not sure why you couldn't find anything, latest mobile finder worked fine here, so Engage Souls key is now in the list. Note that the key is for playmarket version and it may be different for qooapp version (but it can be the same, not tested).
Not sure what the problem is, but in some cases mobile finder can probably work longer than maximum registered time (70 minutes on my 2-core laptop). For example, a laptop can significantly reduce maximum CPU usage available for Java VM based on power settings, especially when it's working on battery, so the total search time will be increased accordingly.
@Amort: It seems some of game archives are additionally compressed with lz4, like your example. Specific script for Fable Legends is added to the scripts bundle (see my signature). The script should work with all game paks, and also it produces full correct paths for extracted files, which is not an issue since like 4.11 engine.
Maybe it will be also helpful for other old games, where full path or root folder is stripped from the resulted files. I've included BASE_PATH_INCLUDED option to the script, if it's set to 0, the script will try to add base path to files (it's default value). For all modern games it should be 1, but you can always test stuff.
@ili: I suppose you're using outdated bms script, incompatible with 4.25 games. Please use the latest one from my signature.
