Thanks for your suggestions, but I just went ahead with acquiring a regular version of this title and it works fine. In fact 99.9% of my sizable backup library works just fine on 3.41, so I'd rather not jeopardize that situation by going to 3.55 just yet.
's still a thriving 3.41 community out there and there's good reasons for that, although I'll admit ignorant complacency shouldn't be one of them.
I tried on 3.41 and didn't work for me. So you may as well blame it on your PS3 Model. I am just saying that it runs for me on my patched Kmeaw 3.55 cfw. I also don't see any point in staying on 3.41 because there is no risk at all in going to 3.55, unlike CEX-DEX, DEX-CEX.
You can update to latest 4.25, go to psn, buy PS2 title in store and sniff PKG link. Then downgrade with hardware flasher and swapped HDD to 3.55, when you on old 3.55 cfw swap old hdd and reinstall 3.55 rogero and backup 'exdata' folder with your act.dat (don't use QA flag before backuping, it deletes act.dat on reboot). Then convert console to 4.21 DEX, install PKG and transfer backupped exdata folder.
