sure, here is the log file https://www.sendspace.com/file/81zkci , so in short: i can use the marge option correctly to add the modded textures with the UI updated version of your program , and i can compress and decompress the base non modded archive with the original textures , but when i decompress the archive that was modified with the marge option to get the modded textures , i get that "null" png file , and the game crash on startup even if i recreate the main.zzz immediately and without do any change , it is like the main.zzz get corrupted during the extraction, and i can swear that i never dared to interrupt the process of extraction , infact i only start to do something when the program tell that the extraction is ended and the program switch to the folder of the main.zzz archive that got extracted ,still when i take a look at the log file , it suddenly stop to show the progress , before the end of the extraction , you watched the log file ? you now know where is the problem ? it is important because if this problem doesn't get solved then it will be impossible to recreate an updater main.zzz, for now the only thing that work is the merge option
I added the length checker it'll be in the next version. Per google the max path length is 260. Your folder you keep the main.zzz in is 176. And the longest path in main.zzz is 79. So 176+79+1 = 256. It's a limit of most windows things including the libraries in C# I use to code this.
The null.png is actually a real file. I dunno what it's used for, but it exists in main.zzz
Can you get a screenshot of the error box that ff8 gives you? I cannot get mine to crash.
What I did was I unpacked a main.zzz that I had previously merged to a folder and repacked it. *shrugs*
Also the log was incomplete mine is like 56039 lines heh though mine is unpacking and repacking. *shrugs*
Though mine also incomplete... I guess i need to fix that too. must not be writing everything before exit.
I feel like it isn't the biggest issue.
You could also download qt-zzz and try them out see if you get the same issue.
You can mod the game with merge so I'll consider that a win for now.
