Pulled off of somewhere, probably either TPB or 1337x. NOT my release. Credit goes to original release groups.
1. Set system local to Japanese
2. Mount SENGOKU.iso
3. Install with als_inst.exe
4. Install translation patch
5. Copy translation patch update to game directory
The HCG are just bonuses and are not needed for the game to run, ie. you don't copy those anywhere.
