Anyone got any news about this? Keep up the good work!

Hi Shaggie good to see we have the same model.

Have you done any testing yet as to the W,x,y & z signals?

I just got my drive tonight, I'm gonna have a look for those sinals whene I get back in..

Has any managed to dump the firmware from the xbox rom yet? If so how about a heads up

chat to you soon, Val

[shaggie]

Hey val!

Nope, no testing done .. What so ever..

Contact me if you find something intressting!


See ya!

[valius]

Found X it's the little red dot in the top left of the PCB.



Not found Y yet but we can use superfro's idea in his tutorial.

not checked for Z yet & I aint looking forward to it!!!!

Hey guys,

Looking at the pictures the two drives look identical, except for the xbox dvd connector plug. Since the signals you are looking for are being sent to that plug, wouldn't it be really easy to find the points if you used the 8050 as a map. Simply follow the traces back and we should have the points.

Once we have the points, we are still going to need a copy of the 8050 firmware inorder to read xbox originals. So, we need to find a program to d/l the firmware off of the panasonic chipset, or someone needs to desolder the sst chip and use a chip reader.

Still working on the signals, not had a lot of time on my hands + the drive I was using decided to bottom out on me so I have ordered another it should arrive some time next week.

Thats is a good idea though I like it, the only real problem I can think of it reversing the power to the drive motor, it looks a lot more complicated than the sammy conversion...

I'll update you on how I get on.

I'm not 100% sure we will have to reverse the power to the tray motor, but even if we do, why would it be more difficult than rotating the motor 180 degrees?

Is anyone working on getting the firmware off of the xbox 8050 drive? I am trying to get ahold of the dangerous brothers over at rpc1.org, to see if they have a program for the 8163b or similar, that could work on the 8050.

We will need the firmware soon!

[valius]

As you can see from the pics below the drive motor is part of the pcb & nothing like the Sammy version.

These pics are from an earlier drive model but the same build technique has been used for the newer versions..

You don't reverse that motor, you only reverse the tray motor. The xbox disks aren't like gamecube disks, they are spun like normal dvd/cd's. If you look at a sammy tutorial, reverse the tray motor not the spin motor.

well then what do you have to reverse the tray motor for then? i thought that the discs had to be spun the opposite direction to normal, as a copyright protection scheme.

I think it is that they read from the outside of the disc in. Normal discs read from inside to out.

[LenteSubigo]

No, xbox disks are read exactly as a normal dvd is read. The copy protection, is some sort of formatting change. I'm not 100% sure on this, but I think they just have a different file system, instead of FAT or NTFS, and signed code.

The reason you need to reverse the tray motor in a sammy is because the firmware says to close the tray when it means open, and vise versa. If you press the eject button on a sd-616t/f with sd-616t/f firmware on a pc the drive works fine, if you flash sdg-605b firmware the tray will not open, because the signal says close, but if you manually open(paper clip) the drive and put a disk in then hit the eject button, it reads fine.

We may not have to reverse the tray motor, but if we have to it will be very easy. The first thing we need to do, is get the firmware off of an xbox LG 8050. Then we need to find all the signals. Test and see if we need anything else, or if the firmware will be compatable at all. It is still possible that this simply won't work too.

getting teh firmware is the only thing that is holding this project up. getting the signals should be very simple. just get a xbox lg drive's pcb next to the pc versions one, and track down the signals. as i said, it should be too hard if you have to two boards right there in front of you, sitting side-by-side.

Good news,

I got a reply from the Dagnerous Borthers, they gave me an app that should be able to dl the firmware off the 8050, who has one they can connect to their pc and d/l the firmware? PM me and I will email you the app. It is very small, 36k.

Once we have a bin, I have to send it back to the dangerous brothers, and they will make us a working exe to flash the 8163b. By the end of the week there may be 2 replacement dvd drives! If so lets make sure all the contributers in this thread are mentioned the the tutorials!

P.S. All you need to connect your 8050 to your computer is a yellow dvd cable you are willing to splice into a molex connector (pc power plug).

[zoleet]

Dont have to. Just boot up in the x, and the grey cable is connected to a pc, thats it!
