I was looking for help reverse engineering .bsa and .an3 animation files from LEGO Star Wars The Complete Saga. For each .an3 file there is a corresponding .bsa file with the same name (Some .an3 files dont have corresponding .bsa files), .bsa files are considerably shorter than the .an3 files so they are probably not the actual animation but maybe metadata or something like that but the .an3 files are definetly the real animation and are much longer each .an3 starts with "4INA/ANI4" (Flipped for some reason, seems to stand for Animation 4 or something like that) that is then followed by possibly a header or some metadata after that there is the name of the animation in this case "dizzy" every single .an3 file ends with "C" followed by a long line of 3's "3333.33333.33" other than that I cant figure out much else. Help from anymore more experienced and better at this would be MUCH appreciated Test .an3 .bsa files.zip

I have been wanting to properly extract and view _nxg.ghg files from LEGO Indiana Jones 2: The Adventure Continues (PC) but there arent any great tools for doing so. These files are character models but they dont have textures, textures are stored in a different file somewhere else and arent too hard to extract. Each file has different chunks starting with "02UN" or "NU20" (Each chunk name is flipped for some reason) thats followed by "OFNI/INFO" which is the info chunk of the file, it has "ukhtryggva" (Code name for the dev who built the file) then the build date "Tue Jul 21 12:02:51 2009" then comes the "LBTN/NTBL" (Nametable chunk) which has "default_string" then followed by a long list of names like "TT5_Blowup_NG", "LeftFoot" or "TT8_Hat_NG" and then comes the "HGXT/TXGH" chunk after that comes the "SDNB/BNDS" chunk then the "HSEM/MESH" (Most likely mesh chunk) after that at the end of the file there is a "LTMU/UMTL" (Possibly material/lighting/uv chunk) There might be stuff I missed so if anyone can help with reverse engineering this file format that would be GREATLY appreciated 🙏 Test nxg.ghg files.zip
