First of all, this game is running great on my i7-4770K, 16 GB, GTX 1080 Ti, Windows 10 Pro v1803 64-bit PC using the latest v398.82 WHQL graphics drivers from NVIDIA. I am running it maxed out at 2560x1440 with SSAAx4 and framerates are always way above 60 fps. Great stuff, no complaints there. However, I am unable to save the game at all. The first S (Save) point after the opening credits allows me to select Save then click on Create Save but nothing appears to happen. If I select the Save option again then I see Create Save rather than a save file as expected. I even tried enabling the SaveAnywhere option (changed it from =0 to =1) in the settings.ini in AppData/Roaming/SEGA/Yakuza0 which brings up the Save option under the pause menu but it is exactly the same as with the save (S) points. I know the game has not saved because when I exit to the title screen (clicking OK to the warning about losing unsaved data) then the only option available for the gameplay is New Game. There is no Continue or Load Game option. I lost almost 2 hours of progress last night due not being able to save. The odd thing is that the backup_9999.bin file in AppData/Local/Sega/Yakuza0/backup_data shows a timestamp that suggests the game *is* saving data. So why can I not resume this save? To make matters worse, when I quit the game by pressing Y on my Xbox One Elite controller then the game appears to hang and never exits to the desktop. If I bring up Task Manager using Ctrl, Shift + Esc then the Yakuza0.exe file is shown as Not Responding and I have to manually end the task. I've tried revalidating the game twice (all files reported okay), I've deleted the two Yakuza folders in AppData and I've even uninstalled and redownloaded the game but these issues persist. I understand this game uses Denuvo, which I don't have a problem with in other games, but I'm wondering if this is the cause of the problems I am experiencing? Has anyone else come across this issue and found a way to get around it? I don't believe there is a problem with my PC as every other game works fine and saves properly. Of course, it could be a conflict with something else I have running such as iCUE or something like that. Will try a clean boot and report back.
