Hooray for no more bootleg source code! (Well, at least not easily)

I've now updated, it should take any size icon. Compressor now performs less checks on the EXE you feed it, so make sure you've passed it through the anti-decompiler first or it will probably corrupt the output.

I always prefer to use the latest version but finding I'm using it an awful lot, so for convenience I've done similar to van0014 and created a shell for it except mine allows you to update the Anti-Decompiler as new versions become available (I used to use van0014's but it wasn't updated to the new version so reverted back to manual processing).

On first run it will ask you to point to the location that you unzipped the Anti-Decompiler into and create an ini file which it then references each run afterwards. Other than that it works exactly the same as van0014's, just with slightly different message boxes (hey, there's only so much you can do with a shell right?).
I think I've managed to trap any errors that might occur during the processing but let me know if it messes up in any way please

Just saying, but under Windows 7 antidec process remains online after closing the program. Is it meant to do so?

[M_I_Soft]

Score_under has released an update for the main antidecompiler.exe, but as yet not the compress.exe, it seems to be a problem with Windows 7 that holds the supporting windows dll's open unless they're given an explicit close command.
Hopefully he'll be back in touch with me soon to let us know compress.exe has been sorted the same as the main antidecompiler.exe.

Happens on XP too...

[Levi224]

Both windows 7 and XP hold recently used dlls open for quick use just in case you happen to want to use the program again in a short amount of time.
@Score_Under
I love the anti-decompiler. Very small size to download(way easier for my horrendously slow internet), plus keeps large games from decompiling easily. Too bad hackers will find a way around it sooner or later. there is always a loophole... So I wonder how good the next versions will be. Good job once again!

[YellowAfterlife]

What are you folks saying? I assume that noone of you had a look a program source, thus could say, what's the matter.
Few days ago, after experimenting with this program for some time, I found a couple of antidec processes idling.
That does not feel like library, more like unfreed dll... or something odd.

Actually I spoke to Score_Under directly and he knows what the problem is and how to fix it - hence he's already done the main antidecompiler.exe - let's face it he's not getting paid for the time he puts into this so until he releases the fixed compress.exe I'm happy to sit and wait for him to sort it out at his own pace.

[score_under]

Well, sorry about the delay; my own pace seems to be rather lethargic as of late. Anyhow, I've made the same modification to compress.exe now (not going to mark these in the changelog as it's not very noteworthy; really, I wonder if people read it anyway ).

[teej]

For one, I read change logs. because I care.
Thank you very much. Keep up the updates!

[True Valhalla]

As above, thanks!

Is game compressing is safe?Won't it damage graphics quality?

Absolutely yes and absolutely no.

Absolutely yes and absolutely no.

So will it or no?I don't understand what you mean by that.

Forgive my unsleepness; let me rephrase it:

Absolutely yes.

Absolutely no.

Thanks.And maybe you can explain this "Do not use any self-check scripts with this (e.g. debug checker, or checksum DLL), as it voids the checksum and debug data." ?Thanks again

P.S. And what is code snippets and why anti-decompiler asks me if I want to remove them?

Do not use any self-check scripts with this (e.g. debug checker, or checksum DLL), as it voids the checksum and debug data.

This is simply because the game data will be encrypted by the anti-decompiler, meaning that if you tried to use a debug checker script (that looks in the game data to see if someone's used a debug forcer), it would falsely say it is being debugged, and if you used a DLL to confirm the checksum of the game data, you would need to make sure to adjust the checksum inside the DLL to match that of the new game data after applying the anti-decompiler, rather than the old game data.

Code snippets in the error messages are the pieces of code shown when an error occurs, to give you a better idea of where it occurred.
Normally, an error message might look like this:

___________________________________________
COMPILATION ERROR in string to be executed
Error in code at line 1:
asdf;
^
at position 5: Assignment operator expected.

With the option to remove code snippets, it would look like this:

___________________________________________
COMPILATION ERROR in string to be executed
Error in code at line 1:
^
at position 5: Assignment operator expected.

[Windsdrow]

And what if I unchecked "Display error messages" in game maker.Than they won't appear?

Edited by Windsdrow, 25 April 2011 - 03:30 PM.

[Big J]

Precisely.

If your game doesn't even show errors, they won't appear.
