Not really. The Resident Evil Operation Raccoon City was hard one to fix in weeks and finally it is being playable today. This will be one too. No worries. Very soon.
I used your tool to fix the eboot for 3.55 and put that together with the .sdat you linked. The game starts, installs game data and then complains about not being able to install trophies and forces me to quit to xmb. No option to actually play the game
