Precomp+Reflate+Srep+LZMA

Reflate Method of Compression



Hello everyones
:POST
--------------------------------------------------------------------------


This is an example to compress games and install via command line.

--------------------------------------------------------------------------

precomp+reflate+srep+lzma
or
reflate+srep+lzma


--------------------------------------------------------------------------


Reflate (By Shelwein) modify to integrate precomp+srep+lzma (by gozarck)

Reflate = (raw2hif.exe + rawdet.exe +rawres.exe):

Reflate, is not a compiled program, but is a
compression method by using the command line in combination
with three programs (raw2hif.exe + rawdet.exe +rawres.exe) .

Acts like precomp, inflating preparing them to compress files with Srep + lzma

but if you want more compression you must use this form precomp+reflate+Srep+LZMA

Precomp inflate the files then reflate makes more bigger, the SREP will compress improve some bytes and LZMA finish the job.

--------------------------------------------------------------------------


all you need to pack games with this methods.

Download => reflate_GOZARCK.7z


--------------------------------------------------------------------------


PD:

seen in some post eh this compression method

Code:
arc.exe a -ep1 -dses --dirs -s; -lc- -di -i2 -r   -msrep+delta+lzma:a1:mfbt4:d200m:fb128:mc10000:lc8
and prompt some users say
ERROR: can't allocate memory required for (de)compression

and the compression stop

the problem is this part of command "d200m"

this option is the dictionary size, so if you use
"d200m" you need 2100MB of ram

How to know?, is simple.
multiply 200*10.5 = 2100mb of ram
if you donīt have enough memory change "d64m"
multiply 64*10.5 = 672mb of ram

but you can limit the use of ram to compression in this seccion of command:

arc.exe a -ep1 -dses --dirs -s; -lc- -di -i2 -r

change to

arc.exe a -ep1 -dses --dirs -s; -lc512 -di -i2 -r

or any number you need

-lc (limit ram to compresion)

-ld (limit ram to decompression)

arc.exe a -ep1 -dses --dirs -s; -lc512 -ld512 -di -i2 -r
