Error extracting tracksplit.pssg

[victorbush]

Open \locations\germany__germany_rally_01.nefs. Try to extract tracksplit.pssg.

Following error happens:

Error extracting item tracks\locations\germany\germany_rally_01\tracksplit.pssg.

This is the only file with which the bug happens in all locations nefs. Also the weird part is that it always crashes on the same block even in different files 6540 off of the top of my head. But I might be wrong.

Tried to look into it but am stumped.

I also get this when extracting s_amb_germany_rally_01.bnk.

Also strange note: when extracting the tracksplit.pssg, it seems to choke on blocks of 0x10000 bytes. If i skip those blocks and treat them as unencrypted/uncompressed (just copy them direct), then I can open the resulting pssg file in the pssg editor.

That hack didn't work for s_amb_germany_rally_01.bnk though.

[opcod3]

Incredibly weird... Maybe there's some metadata in parts 5/6/7/8 of the header we're missing for these blocks.

Also have you checked the that the files extracted from pssg and the size are correct? If I recall correctly PSSG files will open even if semi corrupt.

[victorbush]

File size is correct. There are 797 chunks that it chokes on. The PSSG viewer allows browsing of most textures, but there are some that it can't view, so possibly some corruption in there.

It seems treestextures.pssg is suffering from the same problem. (usa rally 0 from DR2.0) https://github.com/ptasev/Ego-Engine-Modding/issues/24
