Replacement for TSUnpack

Hi All,
Some time ago, Jeffrey Krausyao mentioned that a replacement for TSUnpack was being developed. I was fortunate to be able to locate the site and obtain the executable and source files. Unfortunately, I couldn't get the executable to work, so I compiled the source files and the resulting binary file worked, but not properly, especially with regard to the Open Rails profiles list. I discovered that the software WOULD work with older installations of OR - this is because the profiles are now stored in the Registry instead of a separate file on the hard drive. I have attempted to contact the author, but without success. As the program is covered by the GNU General Public License, I am permitted to make any changes deemed necessary and make it available for free.

The program I've uploaded has the Open Rails selection disabled, but I'm taking a crash-course in C# in order to re-instate it!

I hope the readme contains everything needed, but please contact me if you have any problems. It has been tested on XP, Vista 64-bit, Win 7 32- & 64-bit and Win 8.1 64-bit, with help from Alec (rufuskins) and David (dforrest).

It is now available as UKTS file ID 34103

Cheers,
Ged

Hi Andy,

see if I can work out what the issue might be.

You've got me puzzled, mate As far as I know, I don't have an issue with it -- Now!!
I am currently testing what will be the final version, although experienced C# programmers may complain at what I've done, but at least, I think it works Anyway, if they don't see the source files, my secret is safe

Cheers,

Hi Everybody,
Having done some more tests, I've come to the conclusion that this program doesn't do what it says on the tin! This could be why the original author abandoned it, but a note to that effect anywhere in the source files would have been appreciated!!

I, therefore, apologise to all who've used, or tried to use, it, and I have asked Peter to withdraw it from the UKTS library, at least until I'm happy with it (if that ever happens!).

As I mentioned before, I'm very new to C# and could well be struggling - I can supply the source files to any more experienced programmer. As a side note, the original author states he used Visual Studio 2008 whereas I'm using Visual Studio Express 2013; it automatically converted the files, but could that be the problem?

Cheers,
Ged

Hi All,
This is a short update on my adventures with this program

It seems that if the apk file is less than 5000 bytes in length, it is unpacked without any problems, but I'd like confirmation, or otherwise, from any who were able to download APKExtractor.

The limit may be imposed by the zip routine being used, or its parameters. There's nothing in the program, that I can see, which imposes such a limit, but it could be that the call to the zip routine requires a parameter to over-ride a default value. This is the direction of my current investigations, but if anybody has any other ideas, I'll be pleased to hear them. For information, the source program is written in C# with Visual Studio Express 2013 being used to build the executeable.

Regards,
Ged

Hi All,
Update.

As I suspected, the problem with unpacking some apk files lay with the external unzipping routine (dll file). Changing to a C# built-in zip unpacking procedure resulted in success where there had previously been failure.
However, testing with larger files uncovered a problem with how the original author had made some assumptions regarding the format of the unpacked apk file. Without going into technical details, I have been able to work around it and these large apk files now unpack correctly (up to now!). Ideally, it would need a complete rewrite of that part of the program, but my C# skills aren't up to that level ... yet!!

I've made it my target to get 50 apk files correctly unpacked before asking for testers, but please let me know if you'd like to help. I'll not be running the 50 activities, but will be comparing the files created by APKExtractor with those created by TSUnpack using file/folder comparison software.

I've also got the program working with newer versions of Open Rails, which uses the Registry, instead of a file, for holding its Installation Profiles.

Onwards and upwards!!

Cheers,
Ged
