PS2 Backups on PS3 TESTS

[kompas]

The people know is easy made PS3 Backups from Their own originals, but not are possible test if the backup are ok, not exist the loader :cool: we can't test.

For that i investigate if i can dump my original PS2 games and run in my PS2 in one PS3, i test with Jack&Daxter platinium version.

In Linux PS3

dd if=/dev/cdrom of=/tmp/jakps3.img

2852160+0 records in
2852160+0 records out
1460305920 bytes (1,5 GB) copied, 253,673 seconds, 5,8 MB/s

In Linux in VAIO PC

dd if=/dev/cdrom of=/tmp/jakpc.img

2852160+0 records in
2852160+0 records out
1460305920 bytes (1,5 GB) copied, 245,538 seconds, 5,9 MB/s

And using DVD Decrypter in Windows XP

The Final Result:

ps3 md5 :
aa080bbacde5cb200d43145b58d9c36f

pc linux md5
aa080bbacde5cb200d43145b58d9c36f

pc windows md5
aa080bbacde5cb200d43145b58d9c36f

seems the PS2 backups maded by PS3 are ok, i dunno if PS3 dumps can be same, or hypervisor hide some data or change random data in these dumps.


That's All. :p

well if the md5 are correct the file should work, because if the file is 1 byte bigger you will get an other md5 string

um not necessarily true, it might be the same in md5 structure but i have seen rare instances where the md5 checksum would note an exact same string (i have seen this twice on a DATA.DAXR file on the PSP) so i can't rely completely on the md5 you'd need to test it to really find out if it's 1:1 or skewed.
