Which version of Dragon's dogma? Bles? Blus? were you using a crack/fix? Which one?
I have the elf dumped from your core dump, and made an eboot from it already, but i don't know which version of the game this is for, or which eboot i should match it with. It seems different from the exetrimall bin/elf i found.. and i need to be sure the dump is ok, and we can get elfs from core dump.
As for creating coredump/crashes, there's a number of scenarios that will lead to a crash offcourse. Bad files, missing files, removing USB storage when it's loading things. Sometimes even on a normal OFW ps3 things will crash and beep, but then we don't get a coredump file.
Can you provide your settings for the core dump/dex you are running? So others can get dumps more easily?
