Higurashi no Naku Koro Ni Sui [BLJM61255]

[Nezarn]

according to the console, not open the magic data.rom

If it can't open the data.rom, then why isn't the error in the log? In the log the only thing it can't open is the patch.rom, and that shouldn't matter if the game doesn't have updates\you didn't installed any updates.

Also since this is a disc game, and rpcs3 can't handle disc games correctly in some cases (at least i've found some games that even fails to run because "corrupted data" if the disc game is in dev_hdd0), try moving out the game from dev_hdd0 and start the game with Boot -> Boot Game.

But before that, try LLE the modules Annie posted.
