Questions about dumping multi track ps2 games

[puppydee]

Oh my, I'm trying to dump my first PS2 game with 2 tracks by watching the tutorial but I'm stuck at the first hurdle. I've counted back to find the garbage and I have 21 lines of garbage, How many bytes is 1 line of garbage?  Maths was not my strong point at school. My school report read "We've never seen him in class yet", lol. So expect a few/aload more questions in this thread. Once I've done one I'll master it. Thx for the help:)

Just count the characters. Every double character is 1 byte.

In 1 line you have 16 double-characters, like this for example:

12 54 61 21 54 31 51 32   21 21 54 87 15 24 13 14

16 bytes

if you have 21 lines of those, it's 16x21 = 336 bytes

beware that there are cases where you have 20 lines + 1/2 line,
meaning that the last line has 8 zeroes (00) in the end

in that case you count 16x20 + 8 = 328

divide by four to get the samples: 336/4 = 84 samples
328/4 = 82 samples

I guess its best you post some pics, when your drive's read offset is +102 its not really understandable to have 21 lines of "garbage". Maybe its 20 or 22 lines(?)

And some info about: drive read offset + sectors amount you was going backward, would be helpful, thanks

Hello m8, listen, I've given up on doing multi track discs it's waaaay over my head and tbh it takes quite a bit of messing and I'll only end up stuffing it all up so I'm sorry to say but I'm sticking with dumping single track games and leaving it to the experts and besides I'm really busy anyway without needing extra time to do these. It's took me 2 hours just to fail

Many of life's failures are people who did not realize how close they were to success when they gave up.

puppydee could you please tell us the title of this game, so we can at least take a look for that?

[puppydee]

Certainly it's Operation WinBack SLES-50155

My drives a Pioneer DVD-RW DVR-116D 106

Here's a pic of the garbage. You know if you want you could always log into my pc via logmein to dump this disc if you want?

If nobody else wants to do it, I can.

okay, that's fine, your drive read offset is +96, that means disc write offset is -12.

you can dump that disc yourself also, use +84 (lines from isobuster) value in EAC, try to detect the pregap by pressing "F4", if your drive is not able to detect it, then extract that track without pregap and add it afterward to the beginning (hexeditor or by using COPY function with dummy file)

you can let somebody do it also, its a task of some seconds, if you wish let me know and i will do it.
