I can not make it work, i tried the installation procedure with different versions as mentioned in comments, whatever i do i get the corrupted file thing. im doing everything in the order described, it says it works in the program itself its when i try to start bdo it doesnt work and makes no difference what version of any of the programs i run. By the way, have you thought about making these 4 programs into one unit? it used to be really straight forward using this tool but now it feels a bit like a clusterfuck. I do indeed apreciate the work don't get me wrong, i just feel it is a bit hard to understand what everything is for now.
Each "program" is unique in functionality.
BDO Toolkit is a library, to be used by any program wishing to patch the game or read the supported formats by the library.
Meta Injector is a general purpose patching tool.
Restore N' Patch provides a way for users to avoid the file recheck on updates, while also automatically patching the game when updates happen, as long as the programs that patch the game support it.
Resorepless is a configuration tool for all your lewd needs, and while it could have it's own patching (and it would actually be way more efficient), it currently does not since it's still not using the BDO Toolkit library, it wasn't ported yet and the patching done by the library is different than the "legacy" patching method which no longer works for some file types.
Outside of Resorepless, which would no longer need Meta Injector once ported to use BDO Toolkit, none of the other programs or the library would be unified as they all offer different functionality for different purposes.
