Since last official version original method 1 have been renamed to method 0
and it undergone certain changes. Methods 2, 3, 4 have been renamed to 7, 8
and 9 respectively. Method 0 should work with all drives as long as they
are supported by one of memory dump commands, so if drive is unrecognized it
is preferable to keep method at 0, and try all commands. If one of such
combinations turns out to work, you can proceed then testing other methods
with this commad. In case none of commands work, you could try to determine
drive's Read Buffer command's parameters with supplied 'BruteForce3C.exe'.
Generally program's overall bahaviour regarding commandline haven't changed
and you should be able to use same options as with official versions, though
in case you were using unrecognized drive, which would nevertheless work with
Hitachi command, you'll need to set command to 2 now (e.g. --command 2) and
method to 7, 8 or 9.
Performance have increased since official release and should be now about the
same as with 'RawDump'.
Regarding supported drives:
1. Hitachi-LG GDR8161B, GDR8162B, GDR8163B, GDR8164B, GDR8082N
Those drives can read GC/Wii media without swapping. Expected performance is
1600..1900 MB/h for *4B, *3B and 2100..2600 MB/h for *2B, *1B. Custom memory
dump command is used, which returns 2064 bytes of data. It was reproted that
they can not read other (e.g. PC) discs this way though, this needs
confirmation.
2. Lite-On LH-18A1H, DVDRW LH-18A1P, DVDRW LH-20A1H, DVDRW LH-20A1P
Reading performance for PC DVDs can go up to 5000 MB/h, which means program's
core as well as new methods are capable to output data at least at this rate.
Reading performance for GC was about 1600..1700 MB/h so likely this slowdown is
caused by drive logic itself. Though I only had one GC game to test with, so
possibly better results can be achieved depending on media. Best results were
obtained, when using method 5 with parameter 16,27 (--method5=16,27). This
combination isn't set as default because it can cause noticable delays
depending on medium quality and to make methods more general for use with other
devices. Lite-On won't read GC/Wii DVDs at all without swapping. Lite-On
returns 2384 bytes of data (2064 + ECC) by means of vendor specific READ BUFFER
command. Tested with models LH-18A1H, LH-18A1P and LH-20A1H.
3. Plextor
Plextor would return 2064 bytes of already unscrambled data with READ BUFFER
command. It works good with ordinary DVDs but due the lack of streamed reading
support is practically useless for GC/Wii dumping because of very low
performance. Works nevertheless and could be used for some experiments and
testing. Results from PX-760A.
4. Toshiba Samsung SH-D162A, SH-D162B, SH-D162C, SH-D162D
Returns 2384 data bytes per sector like Lite-On does. Appears to support
streamed reading but performance with tested model (SH-D162D) was somewhat low
and unstable even with ordinary DVDs. Looks promising, if only good-working
method could be determined. Latest drives added, definitely need more testing
at this point.
