WANTED: Teboview / TVW file format specification to write OpenBoardview decoder

Re: WANTED: Teboview / TVW file format specification to write OpenBoardview decoder

Removing the password is trivial.

I took a file which has a password in it, and removed the string that occurs after the .G34S string and set the string length byte to 0. Now is readable in TeboView 4 without requesting the password.

Oddly the Gigabyte file didn't open in TeboView 4 even after stripping the password… But forcing the previous string to "G34…" stopped it from complaining about license :-)
Opened a PR with a python tool to strip the password.

Anyone want to throw a theory on why some of the TVW files have this extended sort of header before the first labelled layer?

Seems there's a few occurrences of the 0 3 2 1 sequence in it.

This is the Gigabyte file that was attached in a slightly earlier post here in this thread.

Oh my, how did you conjure this up? Inside knowledge or just worked out the crypt?

I never use teboview
just search and compare

license must match in the program to open the file. otherwise failure
The license can be modified in IctViewLicense.dll

Re: WANTED: Teboview / TVW file format specification to write OpenBoardview decoder

So their licence "name" is locked at 7 chars (max) ?

At least with the decoder we won't need to worry about that, but at least it's nice to know what that field is for.

Re: WANTED: Teboview / TVW file format specification to write OpenBoardview decoder

no idea for 7 chars,I just tested like this

Re: WANTED: Teboview / TVW file format specification to write OpenBoardview decoder

Hmm so possibly other strings are encoded alike ?

Re: WANTED: Teboview / TVW file format specification to write OpenBoardview decoder

if I have time I will try to make an excel table as usual to decode

Was thinking the same, like the other headers. Just off to sleep again, but worth trying on those other strings in the header.

First byte 07 is sum of chars .

07 47 33 34 76 53 34 7A 00 11 59

_________ HEX ____________ASCII ____ DECODE______

07 47 33 34 76 53 34 7A = G34vS4z = LianBao

possible to modify the number of characters but you have to remove unnecessary letters from the dump, just leave 00 at the end.

03 48 6E 49 00 11 59
EX: 03 48 6E 49 = HnI = MxP

8 chars max
blocked by exe, not succeeded in putting more

Many teboview (v3/v4.11/v4.12) with other customer ID in attachements

Re: WANTED: Teboview / TVW file format specification to write OpenBoardview decoder

Added a string decoder for testing, and will add this to the main program later.

https://raw.githubusercontent.com/in...ode-string.cpp

pld@WorkstationTT:~/development/pld/teboviewformat$ gcc -Wall decode-string.cpp -o decode-string

Re: WANTED: Teboview / TVW file format specification to write OpenBoardview decoder

(the 3-2-1 sequence appears to be a header/lead-in as opposed to a suffix).

indicates the start of each chapter or page, the last byte change, I don't know how to explain
exemple:
03 00 00 00 02 00 00 00 01 00 00 00 0E SILKSCREEN_TOP
03 00 00 00 02 00 00 00 01 00 00 00 0E SOLDERMASK
03 00 00 00 02 00 00 00 01 00 00 00 03 TOP
03 00 00 00 02 00 00 00 01 00 00 00 03 IN1

The last byte is the string-length of the layer name.
