Question SuperREP (SREP) Full Info!

First of all 😊
🎉Merry 🎅Christmas🎉

My Question is⚠️
I Like to know about Srep Commands and methods, 😉
i already try Google, and Fileforums, and some others, and i have found this,
and its not much.☹️ so that's why i ask you guys to help me out

http://krinkels.org/resources/superrep-srep.107

https://www.softpedia.com/get/Compre...SuperREP.shtml

I have no idea about Srep,
that's why i ask, and it's really important to me,
Otherwise I don't ask. ✔️

In my experience, i have Try Srep with Lzma,
for testing which one do better.

Those are the method
that i have tried..

srep:m3f:l128:a1+LZMA
srep:m5f:l128:a1+LZMA

srep:m3f:l512:a1+LZMA
srep:m5f:l512:a1+LZMA

and I see l512 is faster then l128, but i didn't see m5/m3 different, and i know *a1* can go up to *a64* but before i do that i like to know about all srep commands and what they do by increasing and decreasing.

So Please Guys Help me out

Run "srep64" from the command line is all written in the info.
Merry Christmas to you too.

What do you mean by Command lin?
you mean srep64.exe open with CMD?

SREP 3.92 beta: huge-dictionary LZ77 preprocessor   (c) Bulat.Ziganshin********com
July 23, 2013    homepage: http://freearc.org/research/SREP.aspx

Usage: SREP [options] infile [outfile]
   infile/outfile can be specified as "-" for stdin/stdout
   "SREP [options] somefile" compresses data from somefile to somefile.srep
   "SREP [options] somefile.srep" decompresses data back to somefile
   "SREP [options]" compresses and "SREP -d [options]" decompresses data from stdin to stdout

Options are:
   -m1: fixed-window content-defined chunking with matches checked by VMAC
   -m2: order-1 content-defined chunking with matches checked by VMAC
   -m3: check matches by VMAC digest (compression memory = 7-8% of filesize)
   -m4: check matches by rereading old data (compression memory = 3-4% of filesize)
   -m5/-mx: rereading with byte-accurate matches (compression memory = 7-9% of filesize)
   -l: minimum LZ match length, default 512
   -c: size of hash chunk, by default as small as required to find all these LZ matches
   -aX/Y: alloc X bytes of those Y bits are set per L input bytes for compression
          accelerator. Y=0/1/2/4/8/16/32/64, -a0 is slowest but requires least memory
   -ia-: disable I/O acceleration to reduce memory usage (-m5* only)
   -tN: use N compression threads (only for -m1/-m2)

   -m1..-m5: index-LZ - list of matches saved at the end of compressed file
   -m1f..-m5f: future-LZ - decompression dictionary will hold only future matches
   -m1o..-m5o: I/O LZ - output file used as decompression dictionary
   -memBYTES: amount of RAM used by future-LZ/index-LZ decompression (extra goes into VM file)
      -mem75% AKA -mem75p means "use no more than 75% of RAM" - that's by default
      -mem600mb means itself
      -mem75%-600mb means "use no more than 75% of RAM minus 600 mb"
   -mBYTES: don't store matches larger than BYTES on future-LZ/index-LZ decompression

   -d: decompression (for -m1o..m5o requires only 24 mb of memory besides of OS I/O buffers)
   -delete: delete source file after successful (de)compression
   -sBYTES: explicitly specify filesize (for compression from stdin), default 25gb
   -bBYTES: change compression block size, default 8mb
   -index=FILENAME: read/write index of compressed data into separate file
   -temp=[FILENAME]: keep uncompressed data in the file in stdin-to-stdout mode, default srep-data.tmp
   -vmfile=FILENAME: temporary file used by Virtual Memory manager, default srep-virtual-memory.tmp
   -vmblock=BYTES: size of one block in VM temporary file, default 8mb

   -hash=vmac(default)/siphash/md5/sha1/sha512: store hash checksums in every block
   -hash-: don't store/check block checksums
   -mmap: use memory-mapped files for match checking
   -slp[+/-/]: force/disable/try(default) large pages support
   -pc[max_offset]: display performance counters [for matches closer than max_offset]
   -s: save printed stats from overwriting; -s+/-s-/-sX.Y: update stats every X.Y seconds
   -v[0..2]: verbosity level
   -rem...: command-line remark

Thanks a lot. 🤗

can you help me with something?

I know how to find Oodle games,
Oodle games have dll file inside the game and Oodle scan tells us which method that game used,
Kraken, Mermaid, Selkie. Jc4 used K&M ACO use Mermaid only. Please Correct me if I'm wrong 🤗

also i need to know, On none Oodle games
How can i find what kind of Compression,
used for the game?

It's very important to me to make best compression method for every game 🎮

just use srep64 with setting m3f:a2...
Yes your Right, i have use m5f:l512:a16 and it took 6 Hours for Srep to complete.

So your saying if i use
srep:m5f:l128:1a VS srep:m3f
Between them it's just a 2% different like 500Mb lower then other..?

can you,
Recommend Best SREP Settings for all games.

What that a2 does?
i have seen the info about Srep,
it's only says
*a0 is slowest but requires least memory..
Please explain.

Corsair Vengeance 3200MHz 8GB x 4 (32GB) DDR4.

i can use all 32GB Ram for compressing,
but i want low ram using for decompressing.

I don't want to limit ram usage for decompressing.
i want to know if i use lot of ram for compressing it will require the same amount of ram for decompressing..

it will auto detect ram amount,
then it use as much as ram for decompressing?
