Anyway I have some good news. After some coding and experimenting with F1 command I can enable reading more sectors from cache.

Great works!!

Added your code and some changed. Test Plz. http://www.mediafire.com/file/eq80y20l9 … st.7z/file

Sth is not right. Cache:

19 Cache LBA 325224 (MSF 72:18:24) MODE 01
20 Cache LBA 325225 (MSF 72:18:25) MODE 01
21 Cache LBA 325226 (MSF 72:18:26) MODE 01
22 Cache LBA 325227 (MSF 72:18:27) MODE 01
23 Cache LBA 325228 (MSF 72:18:28) MODE 01 Lead-out
24 Cache LBA 325229 (MSF 72:18:29) MODE 01 Lead-out
25 Cache LBA 325230 (MSF 72:18:30) MODE 01 Lead-out
26 Cache LBA 325231 (MSF 72:18:31) MODE 01 Lead-out
27 Cache LBA 325232 (MSF 72:18:32) MODE 01 Lead-out
28 Cache LBA 325233 (MSF 72:18:33) MODE 01 Lead-out
29 Cache LBA 325234 (MSF 72:18:34) MODE 01 Lead-out

Image has following LBAs:
LBA[325222, 0x4f666], MSF[72:18:22], mode 1
LBA[325223, 0x4f667], MSF[72:18:23], mode 1
LBA[325224, 0x4f668], MSF[72:18:24], mode 1
LBA[325225, 0x4f669], MSF[72:18:25], mode 1 User data vs. ecc/edc doesn't match
LBA[325228, 0x4f66c], MSF[72:18:28], mode 1
LBA[325229, 0x4f66d], MSF[72:18:29], mode 1

325226 and 325227 are missing.
325228 and 325229 are lead out sectors.

It looks like data is copied from wrong cache sectors.

I forgot to set the offset.

This is some kind of mastering error? I think we've seen it a couple times before with CDi.

Maybe so.

Added your code and some changed. Test Plz. http://www.mediafire.com/file/eq80y20l9 … st.7z/file

I'm not a coder, but it seems like you are trying to combine sectors from cache reads based on the assumption that they are all data sectors with correct sync/header? How will it handle audio sectors or mastering errors safely?

Still sth not right:

Sorry, I couldn't test well because I thought I didn't have a big offset disc. But found it in my room. (Free Software Collection 6 [FMT])
Please wait until fix the bug.
