like mikey said, i would make a video to show you how to compress a game from start to finish.

you need to search files of the game for precompressability, then if they are indeed recompressable they go under deflate mask. if not they go in normal or if non compressable they go to void.

this think can be done by a video easily. :D there are repackers out there that prefer to absolutely squeeze a game and take 3 hours 50 minutes to decompress.

i have made Dragon Age Inquisition unpack in 40 minutes using 4 threads vs a repacker on net did it in 4 hours almost..... learn to be efficient along the way, this is where masks kick in...

It would be kind enough to make a video tutorial to learn how to compress, it would be very helpful for those who walk lost

I got this error , Used it on Windows 10


ISDone.dll

An error Occured when unpacking!
Unarc.dll returned error code:-1


And another error
i tried your Masked Compression v2.5
advanced Data Comp

an error occured while unpacking: Unknown compression method!
Unarc.dll returened error code:-2
ERROR: unsupported compression method msr


On arc.ini i use optimal. \data1.bin -moptimal

howdy panker I am using the 2.5 version and all is well I have just one small issue after the install is finished it is leaving the freearctmp folder and inside is freearc.tmp file left behind which is basically same size as the data.bin any pointer on how to make it delete the files once install is complete?

I had the exact same error on his older compressor but so far 2.5 is working fine for me on win 10 but I am curious as to the solution on this myself as I have searched high and low and found nothing to correct it. However I still have tmp files and folders left behind from the repack and the install :(

i am under exams right now guys :D

I will long when i get free time to fix your windows 10 problem :D

I am using win 10 pro 64bit in no 5.5.9
I am getting an an error code 14 while installing pls help

Hey panker thanks for everything I was able to get perfect results just using -moptimal or placebo nothing left over, but I am now trying to compress the hearts of stone expansion on witcher 3 but what I have found is for some reason once the decompression gets to two files in particular which are of the .blobs variety I continue to get Unarc.dll error 11 with this however I can compress the installer for this hearts of stone without a problem except for the fact it does not actually compress it at all I guess because the format then is one .exe and a couple of .bin files. So unless I can figure out exactly why the .blobs wont extract then their is nothing else I can do beside include the installer separately from the game repack vs the already extracted and placed expansion in the game folder.

this sounds strange ...

can yo utry again ??? maybe post some pics with the problem ?

check crc, i have done witcher 3 before and it had no problems try zstd for it

okay i will try ztsd and report back I removed the expansion and repacked again and I had the same issue so its something else although with the expansion included it decompressed fine until it got to the ep1 folder in which it failed but lemme try with that and I will def report back.

Okay so I had same results with ztsd except that the failure happens alot sooner than with optimal, I am going to try one last thing for now and that is to totally delete the masked compressor 2.5 and remove, then redownload it and start from scratch again, although I do not recall changing anything of importance I do not know what else it could be, Could I get this problem possibly from the source folder being on an external usb hard drive by chance? I am also going to move the entire folder to the same drive I ran the repacker from and finally if that all fails as well then what screenshots should i try to get? I would like to make sure you are able to see what is going on as well if nothing else just to help improve your project I may also run a vm of win 7 just to see if it makes any difference or not. I am currently on win 10 x64 I repacked ghostbusters using optimal with zero probs success from the start but for some reason this one is perplexing. You recommended doing a md5 check could you possibly point me in right direction for this I was not aware their was a md5 checker for witcher 3.

what you describe aint exactly a mask problem but some exe with bugs that is causing this ???

can you find what possibly gives this error ??

also use this

-msrep+xz

just to make sure that it packs and unpacks


EDIT: will give you an update soon ...checking some stuff here

ok just got home going to try packing again with -msrep+xz also the version of witcher is latest release as well if that makes any difference at all 1.12 with all dlc and expansion, I am basically wanting to get this working before the blood and wine drops so that I can get it all ready do you think it would make a difference if I tried to pack more than one .bin or do you think it would still fail using more than one data.bin?


I may also try to install it using blackbox installer vs the corepack just to see if result differs unless you think that is a lost cause.

this is what it is producing for me so is my srep somehow bad? I mean it is the same one that I downloaded from your files have not edited it or changed at all.

trying -msrep64+xz seems to be working so far but so did optimal and placebo etc until decompression which would fail with error -11. So perhaps srep.exe has a prob although not totally certain of that yet without another full pack and unpack using a different srep.
