Opened A Xbox To Find A Hitachi-lg Dvdrom, **MERGED TOPICS** Options

Obviously you don't know shit from apple butter about how to fix this problem.

cheers,

Everyone here knows that you have nothing useful to contribute Tiros, you prove time and time again that you are nothing more than a conceited hypocrite blessed with the mental maturity of a pre-schooler.

Why don't you find somewhere far away to wallow in your own self pity. Are you having marital troubles again?

I have disassembled the two images completely using an 8051 disassembler found here http://pioneerdvd.rpc1.org/disWin32.zip

The outputs look beleivable

I will be very surprised the cpu is an 8051 core

Lets see, so far your contribution to this thread has been nothing more than one "fanboy" post where you try to stick your head up wenids ass, and some completely useless decimal to hex conversions that any retard with a calculator could do. I think everyone here knows that YOU have nothing usefull to contribute. Why don't you post something technical and prove me wrong.
I won't hold my breath

@jannz
Sorry, my whole post was not directed toward you, I was trying to clear up some misconceptions that some others are having.
Since the DLD is created by copying the RAW binary data directly into the file, and only correcting a checksum, it is not decrypted by the flaser.

[skyhi]

Just glancing at the disassembly, there are several obvious, serious problems with it being 8051 code. Why don't you take another look and report back your findings.

All right so it's 32 bit code - I'm a liltte out of my league with this but willing to dig into it.

This link http://pioneerdvd.rpc1.org/disWin32.zip also has a matsushita 102000 disassembler for windows - would that be of any use?

Everyone who has not posted at all has contibuted to this thread far more that anything you have spewed out.

FYI, I am a qualified Computer Systems Engineer with 3 years industry experience and can therefor quite easily see how much shit you have been spinning. the difference between you and me is that you don't know when to hold your tongue and cease insulting people.

WOW!
Your "qualified"!! By who, to do what? By wenid? To give blow jobs?
That must make you an extremely valuable asset to your employer.
You actually have 3 whole years experience???!!!! Do you know what a "greenhorn" is?
You don't seem to be progressing too well. Maybe you are in the wrong field, have you considered McDonalds?

If you know so much, why is your reply so vague?
If you know so much, why don't you explain the "shit" I have been "spinning"? (whatever that means)
If you know so much, why don't you tell us what to do with the hex values you brilliantly converted from decimal?
If you know so much, why can't you contribute even one TECHNICAL point to this thread?

There are plenty of other differences between you and me, but holding your tounge is not one of them. I guess you forgot about your own advice when you chose to stick your nose in my argument with wenid:
Bourke provoke Tiros

I have only responded in this manner to those who provoke me.

[TKramka]

My God, can we just get back to firmware hacking / fixing bugs in the layout... I am looking forward to a 16x CDR reading HL-DT drive, can we just get back to the original conversation.

[menelik]

@ TKramka
im afraid that we obviously cant and will never be able to.

This morning I pulled my 8050L apart again to determine where pin6 & 8 go (on the AN22023 mediatek chip).



on the 8050L, for the AN22023:
pin6 === pin 9 === ground
pin8 === pin 41 == TP515 (also goes to uC33 and uC16)

Looking at the 8163b, for the AN22023:
pin 41 === TP515 fortunately, same nomenclature as 8050L.

I haven't cut my traces yet, but I'm going to soon. With Tiros' suggestions, this is what I'm going to attempt:

8163b:
A. pin6 (dvd power shown below) ==== 1kohm ==== TP126 PINK READY
B. cut TP126 trace, side that leads to AN22023, obviously
C. solder pin 6 (AN22023) to ground.
D. pin5 (dvd power shown below) ==== 1kohm ==== TP128 ORANGE TRAY_OUT
E. cut TP128 trace, side that leads to AN22023
F. solder pin 8 (AN22023) to TP515.
G. pin 4 (dvd power shown below) === EJECT
H. pin 7 (dvd power shown below) === 1kohm ==== TP055 RED TRAY_IN



ABOVE PIC shows:
TP126 PINK READY
TP128 ORANGE TRAY_OUT
TP055 RED TRAY_IN



I just had another crazy idea, that I'd like to try, but I doubt it would work. The idea is to short LDCD to LDDV, possibly telling the drive that when you load a cd-R, it may fool the drive into thinking that there is a dvd inside. Well, its just a thought...

[TKramka]

But wouldn't that make it use a DVD laser, and we would wind up with a DVD drive as good as a Thomson, which uses the same design.

@true
Are you sure 6=9=GND?
On the 8050 pix, 6 is shorted to 9, but I thought this node was driven by Uc.47

I don't have 8050 but for 8163 this is what I found:
Uc.50=22023.6
Uc.63=R/C/22023.7
Uc.49=22023.8
Uc.47=22023.9

Problem #1:
@true: pin6 === pin 9 === ground??
I cut Uc.49 and Uc.50 from the chip.
Connected jumper from 22023.6 to 22023.9, leaving Uc.47 to drive this node.
Are you saying that for 8050 Uc.47 does not drive this node? It is ground? Are you sure? If Uc.47 does not connect here, than where does Uc.47 go in 8050?

Problem#2:
@true: pin8 === pin 41 == TP515 (also goes to uC33 and uC16)
Since I dont have 8050, I couldn't find was what drives 22023.8 in the 8050. If what you say is correct, what drives Uc33 and Uc16 on the 8163? You may have to rewire that circuit too if it is different from 8050.

Please double verify the connection for 2203.8, and the 22023.6/.9 node.

Great work BTW.
You seem to be the only person here cabable of producing any significant results.

Not @True:
What we are trying to do here is make the 8163 Mboard look EXACTLY like the 8050 Mboard. If you want to help, try to find differences.

@true
These connections are looking like they DO make sense. I'm tryin it out tonight and I'll report back my findings.
I wish I had 8050
Great Find!

@all
BTW, I didn't mean he's the ONLY contributor. I just meant that this thread has been stale of any NEW information for quite a while.

Tripple checked this. 6==9==to ground.

Are you saying that for 8050 Uc.47 does not drive this node? It is ground? Are you sure? If Uc.47 does not connect here, than where does Uc.47 go in 8050?

on the 8050, uC47 ====R223 (10k) === grnd, see below.

8050L (shown above)

Please double verify the connection for 22023.8

Double checked this as well. confirmed.



Here's a pic before I cut any traces. I just desoldered the audio out connector from the far side, and pulled the pins up and out. I think it'll make for a cleaner install.

There are plenty of other differences between you and me, but holding your tounge is not one of them.

Gainsaying is one of your only virtues we all have gathered!

I guess you forgot about your own advice when you chose to stick your nose in my argument with wenid:
Bourke provoke Tiros

Is English your second language? 'provoke Tiros' is not past tense; past tense would be 'provoked Tiros'. If you are going to attempt communication in English at least try little man.
