GDINFO

Post by **Quzar** » Sat Aug 30, 2008 3:45 pm

So I wrote up a little program that complements MapleTest and gathers all possible extended data from the GD-Rom drive. The biggest piece of info this returns is the version number of the DC's GDRom firmware, mine happens to be 6.43 with a date code of 990408 (well, I assume that's a date stamp, it makes sense =P). Of course, unlike MapleTest this has no real goal or purpose, just thought it would be interesting.

Eventually I'll throw this into a full program with Mapletest and a few others and give them you know... graphical output and such.

Here's what my DC says:

Code: Select all

The first block of info is the result of sending the ATA command "Identify Packet Device". The spec has it returning 255chars, but this only gives back 80. The first 16 bytes should be some sort of info (non-ascii), then the next three lines are each some sort of identifier, from what I can tell:

Code: Select all

Identify Packet Device (ATA command 0xA1):
0x00-0x02: ?? 
0x03-0x0F: Reserved (??)
0x10-0x1F: Manufacturer (ascii, SEGA tends to pad ascii strings with 20[space])
0x20-0x2F: Device Name (ascii)
0x30-0x3F: Firmware Revision (ascii)
0x40-0x4F: Reserved (??, this isn't here by mistake, when issuing the command it returns this)

The second set of information comes from issuing the Packet Interface code "Request Mode"

Code: Select all

0x00-0x09: ??
0x0A-0x0F: Manufacturer (similar to the above?)
0x10-0x11: ?? (may belong to the version string, but why would they make it "  REV")
0x12-0x09: Firmware Revision (In my case "REV 6.43")
0x1A-0x1F: Firmware Date (YYMMDD)

The last thing is the result of the ATA command "Executive Device Diagnostic" which returns 0x01 on 'OK' and anything else means that there's a problem.

The program and it's source code is attached below. Maybe some of the same people who tried out MapleTest could run this and we'll see if there are other firmware revisions.

Note: This only outputs to console, so it is only for those with a CC, BBA, SLA, etc.

Edit: Added a description of the data as far as I can tell what it means.
Edit2: Chopped the junk out of my output and a typo.
