The download here contains 1057 files, all with the .lz file extension, which were in a folder named "Textures". I have repeatedly tried to extract the file "img-202_all_02_kenzan-000.lz", but the two programs I tried have failed: lunzip and DSDecmp.
If it is too difficult to extract all the files, I'd appreciate if the files starting from "img-202_all_00_karlier-000.lz" through "img-202_all_03_yusei2-004.lz" were at least "solved" (which is 232 files).
The "Yu-Gi-Oh! Duel Terminal" game is played through an arcade machine, but through maintenance and boot-up, it appears to rely on a Windows XP OS, if that helps. Thank you for your time.
EDIT: Here's the download link (less than 1 GB, when unzipped): https://mega.nz/#!A4AVWa7K!9Q_Dy7LprHek ... FyOg9teAAU
This download link only has a file called "tex-config.bin", which was in the same folder as those .lz files. Including here just in case it helps.
