Birdy Xtreme Firmware for Hitachi-LG v46D v1.2 tweak Posted by XanTium | July 8 01:03 EST

Birdy released a v1.2 firmware for the Hitachi-LG GDR-3120L v46D based on Commodore4Eva's Hitachi-LG v1.1 FW on the XBH forums: [QUOTE] This is a tweak of the orginial Commodore4Eva Xtreme firmware v1.1 It include 3 tweak: * 1: Mode B tweak If you start your Xbox with tray opened, the hitachis start in ModeB. Start your xbox, open the tray. Now power off your xbox by disconnecting power supply. Start again your xbox, your drive is in ModeB . Easy ;-) * 2: Tray open/close in ModeB (without adapter, hitachi on power supply from xbox). Correct the open/close tray faulty operation when your drive is in modeb with Windows. Now in modeB you can use your drive without problem. * 3: Dashboard TimeOut tweak with DVD DL ;-) During disk recognition, this tweak fake the open/close function. If your disc are not recognized yet and you received the "Open tray" from dashboard. Press the eject button -> xbox say opening but tray stay closed. Press again the eject button -> xbox say "closing" -- "reading disc" No more timeout!! [/QUOTE] Note that the modified FW is currently ONLY for the Hitachi-LG with FW v46D.

[JohnnyVegas]

nice. How was this coded in exactly?

[OG_WaSuP]

XTRM-HITACHI-ALL-V1_2 is out for all versions in the usual places

[garyopa]

nice. How was this coded in exactly?

Two more areas of the Hitachi FW are now flashed, it the early part of
the drive control area, for setup, opening tray, closing tray, etc.

In the v46 firmware at address :665D a jump to new custom code is added,
which allows for easier Mode B (for next time updates, etc.)

And at address :A956 a jump to new custom code is added, which allows
for re-trying of the disc by pressing the eject button, if OPEN TRAY happens.

The custom code is jammed in at blank space in the FW at :3150 and :3170,
in the same block of blank space used by "c4e" from :3000 thru to :3371

The tweaks are now available for all Hitachi drives (v32 / v36 / v46 / v47 / v59).

Yea, i was wondering why the frontpage post says only for 46. Strange

Good job.

I might try this, although I have no open disc error but "use soft cloth error" Will post experience when tested

If you want port this tweak to other firmware i can explain how it work :
AT 90003150 is the main code for modeB tweak at boot time:
the original code come from 900665d :
9000665a : Movebu (98D),D0 ; tray status value (input)
9000665d: jump 90003150

90003150: btst 0x10,d0 (original code)
90003153: beq 90003167 (new)
90003153: movbu (d930),d0 ; register D930 is internal tray status if bit 1=1 then tray is opened
90003158: btst 1,d0 ; check bit 1
9000315b: bne 90003167;
9000315d: bclr 0x40,(598) ; go in mode A
90003162: jmp 9006680; jump in original modeA routine
90003167 jmp 90006680;jump in original modeB routine

At 9003170 is the tray open, close tweak

Original routine at 9000a956 is the master code who's check the open/close function.
new:
9000a956 jmp 90003170

90003170: extbu d0 (orriginal)
90003171 cmp 0,d0 (original)
90003173 beq 90003181
90003175 movbu (1dc),d0 ; new register 1dc is the status of drive 0= disk recognition 1-opened 2- closing 3- opened 04-closing 06- disk ready
90003178 cmp 0,d0 ; check if status 0 : disk recognition
9000317a beq 90003181 ; yes go 3181
9000317c jmp 9000a95b jump to original routine (tray status changed)
90003181 jmp 9000a96a: jump to original routine (trau status as not changed)


the tray open/close tweak for windows is much easy
it'a at 900a80c
9000a807 btst 0x40,(598) ; mode a or b
9000a80c bra 9000a83e (only modeA tray system allowed ;-) )

I hope that can help all hacker
