Vangsguard Posted June 20 Posted June 20 Did anyone successfully get files? I'm trying to get the models and such so I can rig it and do youtube thumbnails. If anyone successfully got the models can they either send or guide me on how to do it? Any help would be much appreciated

Any help would be much appreciated It seems that there is a model viewer for the neox engine. I am not sure whether it is suitable for your own game.

I've been trying for a long time with no luck. I remember that most games of the same type will store the filename part in several files associated with the original npk, or store them in a list list, and of course some games will store the filename list at the end of the npk file. I have tried to download from the server whether there are list or related npk files, but unfortunately, I didn't download it. Only script.npk has some associated files, but they do not restore file names, I looked at the local files and found no files associated with npk Several url constructions related to file downloads, taking the domestic version as an example Get the latest version number via this link Official server: https://h55.update.netease.com/pl/iosuni_patch_release_force_update_neox2.plist?r=1519 Co-research and service: https://h55.update.netease.com/pl/iosuni_patch_neox2_gongyan_release.plist?r=6961 Build download links through version number and file list Official server: https://h55.gph.netease.com/iosuni_netease_2.90.125221.2268510/script.npk Co-research and service: https://h55.gph.netease.com/iosuni_netease_2.1.1650975.2254182/script.npk Also I found a few extra files, which may have some effect on restoring file names. https://h55.gph.netease.com/iosuni_netease_2.90.125221.2268510/res.mini.skip.txt https://h55.gph.netease.com/iosuni_netease_2.90.125221.2268510/res.npk.map https://h55.gph.netease.com/iosuni_netease_2.90.125221.2268510/res.mini.npk.map https://h55.gph.netease.com/iosuni_netease_2.90.125221.2268510/res.skip.txt https://h55.gph.netease.com/iosuni_netease_2.90.125221.2268510/res.mini.npk.bin https://h55.gph.netease.com/iosuni_netease_2.90.125221.2268510/res.mini.npk.txt https://h55.gph.netease.com/iosuni_netease_2.90.125221.2268510/res.skip.map https://h55.gph.netease.com/iosuni_netease_2.90.125221.2268510/res.mini.skip.map https://h55.gph.netease.com/iosuni_netease_2.90.125221.2268510/res.npk.bin https://h55.gph.netease.com/iosuni_netease_2.90.125221.2268510/res.npk.txt

The above picture with the loaded scene is the aforementioned custom engine reimplementation. Especially in IDV the entities are all referenced in the actual script bytecode those files have been compressed, xored and marshalled. For example the model loader follows a tree structure it starts with a path whose computed hash leads to a buffer with other file references and so on, and that’s what my engine tries to mimic.

So does this reverse engineering require reverse library files or reverse their python files? I know that python scripts may contain some file lists, but the opcodes for each game are different, which also requires some reverse engineering for a specific game to find the opcode. Personally, I think the file name on the Messiah is easier to recover, and most of them only need a resource library file. Edited July 7 by wq223
