PS3 Question about mounting NTFS

[onionat]

Hi everyone! It is kinda unclear to me how mounting an ntfs drive works with webman: it is natively supported or i still need to run prepiso first? I'm on latest Evilnat cfw right now

Second, and i don't know if it is webman or cfw related, does decryption on-the-fly works from ntfs drives?

Thank you

webMAN MOD natively supports NTFS for content scanning or file management.
That means that webMAN MOD can scan ISOs on NTFS without prepISO, but there are some limitations. I recommend to use prepISO.

NTFS games are mounted through raw_iso.sprx no matter if the game was scanned through prepISO or the internal prepNTFS.

The decryption on-the-fly is performed by Cobra 8.5 (CFW feature of 4.91.2 and later). It reads the dkey from /dev_hdd0/tmp/wmtmp

prepISO only copies the dkey automatically to that folder during the content scanning.

Just one question: does decryption on-the-fly stress the console more than run the iso normally and does impact overall in-game perfomances?

Yes, the decryption on-the-fly adds more CPU processing than reading non-encrypted ISOs.
Specifically the function decrypt_iso_data() found in stage2/storage_ext.c is called for every sector read from the ISO.
However, the difference in performace is barely noticeable.

It would be difficult to attribute a slowdown in performance or an increase in heat to encryption.
