Well getting closer but not there yet. Testing it side by side with splatoon (USA) usbhelper : wiiudownloader.
No updates just the core game.
Wiiudownloader:
1) original issue I think was the random special characters that follow the title name e.g. Splatoon&
[email protected] [000500010176900]. WUP installer doesn’t even show folders if special characters are present. Removed them from folder name and now can select to attempt WUP installing.
2) both decrypted and non decrypted get as far as selecting where to install nand/usb. Then fail as the instal begins. Throwing up error “verify WUP files are correct and complete. Dlc/e shop require sig patch”
Usb helper
1) download splatoon
2) transfer to SD (from usb helper)
3) install via WUP installer no issues.
I put the game folders side by side on PC, (usbhelper:Wiiudownloader) same size, same file names, same number of files. Obviously something is different but what I can’t tell.
I ran mocha just in case but didn’t make a diff, and tbh wouldn’t make sense if the usbhelper game installs no issues.
Any other thoughts to try out.
Update: one last test for tonight. Copied splatoon folder from usbhelper download directory to the sd card via windows (not using the transfer to sd feature in usbhelper). Still installed using WUP installer no issues. So usbhelper is not doing anything special when you ask it to transfer to sd card.
