It seems the ps3jb2 loads masterdiscs with fself, with the algo I provided and the right key (which I am not providing) you can decrypt said masterdiscs images right on pc and grab the fself files.


   // do crypt
   unsigned char sector_key[16];
   memset(sector_key, 0, 16);
   sector_key[12] = (sector_num & 0xFF000000)>>24;
   sector_key[13] = (sector_num & 0x00FF0000)>>16;
   sector_key[14] = (sector_num & 0x0000FF00)>> 8;
   sector_key[15] = (sector_num & 0x000000FF)>> 0;
   
   // encrypt sector
   aes_context aes_ctx;
   aes_setkey_enc(&aes_ctx, G_DEBUG_KEY, 128);
   aes_crypt_cbc(&aes_ctx, AES_ENCRYPT, aligned_size, sector_key, buff, buff);
   
   // decrypt
   aes_context aes_ctx;
   aes_setkey_dec(&aes_ctx, G_DEBUG_KEY, 128);
   aes_crypt_cbc(&aes_ctx, AES_DECRYPT, aligned_size, sector_key, buff, buff);

that's the algo for masterdiscs
ps3gen dll has the static keys for masterdiscs
you can also get it from sv_iso
the crappy sdk tool that generates masterdisc images for dex
