I do not know what you mean by "go sfk style" - I saw in your Resident Evil 3 Remake conversion that is some kind of patching tool. I hope you don't mind if I ask which files contain which blocks?

Will this result in a CRC perfect installation (when compared with retail build)?

Thank you.

Let me answer your questions one by one.

Fitgirl went sfk style first and she manages to keep crc the same.
it Separates data in large archives and it makes lolz ridiculously fast and efficient. in some options it completely removes data... foreign languages you dont need.


the above blocks i removed result in all languages being removed and you get to keep what you want from folder "sound" of the game.

Data1.bdh has the entire folder named sound compressed in it, by removing the data you wont miss anything but a bad crc. you can even repatch it after to get it perfect crc match.

another example: DMC5 has a 32GB file which contains 10GB of movies and sounds.

if you sfk remove the 10GB of high entropy low compressability of stuff you will feed lolzi with pure textures and get high compressed file and very good speed.



In order to remove the data from the blocks above you need hex editor or convert them in decimal and use sfk, then zero them out and patch them back into position as shown in re3.
its only 7 blocks so use hex editor it will fast

Using a xdelta or zstd patch or bsdiff is a bad idea since you know what blocks to remove/inject.
