im using Irisman with HEN 2.0 and works perfect, what i have saw different is that with HEN 1.0 Irisman mounted the game in /app_game/ps3_game and there wasnt a disk icon on xmb, now with HEN 2.0 Irisman mounts the game as a disk icon and theres nothing mounted in /app_game/ps3_game, why this happens? i really dunno but the freezings, hard lockups and scary visits to recovery mode have ended at least for me. i have to say that i dont have webman installed, maybe is the culprit in your case.
amazing job with HEN 2.0 devs, your great!!
