I'm trying to compress this title into archives that'll fit into DVD5. I don't really require a fancy installer or anything, just a simple executable that'll let me extract the game's archives where I want (I believe Razor12911 has an archiver like this which I've used with great success in the past) I know that finding the best compression method for a certain set of files requires trial and error but we're all here to learn, right?

Get a deflate precompressor, you can use this one.

srep then lzma, I think that's the method that needs to be used to get an output of something like 25-30GB.

I'm new to this Forum and have one or two Questions.

Is it possible to use xz compressed files with IC 3.0? if yes how? (btw thx razor for this awesome program)

next one is how to use 4x4:lzma... i have a bat that runs but its no difference to lzma

Unfortunately no.

it sometimes all depends on what you're compressing. 4x4 allows a compressor to run in parallel mode, meaning more speed at a cost of ratio. 4x4 splits data into blocks then runs a chosen compressor, this block splitting loses you ratio, but like I said it all depends on what you're compressing, if its something that can be compressed properly by lzma and is long, you'll see ratio difference.

Thx for the fast answer.
For the XZ files... is there an IC like program to use?
and for the 4x4 problem i wrote a little wrong... with no difference i mean in terms of speed. its like 4x4 isnt there at all.... it will be subjetive but i think its even slower then lzma alone. maybe something wrong in the bat?

-msrep64+delta+4x4:lzma:a1:mfbt4:d1024m:fb128:mc100 0:lc8

On second thought, I think it's actually possible for IC update, I wonder why didn't I think of this before.
Making update for XZ support.

srep will fail if u specify less and use more ram if u specify more, is little bit slow too

probably the reason why it is failing to restore things data correctly is becoz of the fact that i don't even store checksums while processing with srep(-hash-)

Actually, srep is suppose to fail during compression, removing -hash- will not fix this, to be on the safe side, don't pipe srep when compressing, only do that when decompressing.
