It seems the ps3jb2 loads masterdiscs with fself, with the algo provided and the right key (which is not provided) 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
