Newbie Question Thread

OK, I am from the old BBS days (Myth, Paradigm etc..) and have been fascinated by extreme compression. These days I learn it as a hobby. So wanted to thank you all for this site.

Sorry I have a noob question.

I know this is part of an arc bat file (I love working with batch), however what is this part

-mprecomp+srep+lzma:a1:mfbt4:d256m:fb128:mc1000:lc8

Because when I run it,
arc a -lc8 -ep1 -ed -r -w.\ game-1.bin -mprecomp+srep+lzma:a1:mfbt4:d256m:fb128:mc1000:lc8 "D:\GAMES\my_game_file\*"

gives me an error
recent one was general (de)compression error in precomp
other times it looks like it skips both precomp and srep and just finishes susccessfully.

How am I using this incorrectly?

Thanks!

The -m parameter in FreeArc specifies the compression method to be used when making your archives.

Methods can be internal methods built into FreeArc or they can be defined in arc.ini as external compressors.

In your case, it looks like precomp and srep are external compressors whereas you are using FreeArc's internal lzma compressor.

Secondly, when you have methods with colons after their name, this is a way of defining parameters for that compressor at runtime.

For example, the oggre compressor by ProFrager, arc.ini would look like this:

[External compressor:oggre]
header = 0
packcmd = {compressor} {options} $$arcdatafile$$.tmp $$arcpackedfile$$.tmp

FreeArc has many internal constants, two of which I have shown above.

{compressor} instructs FA to look for oggre.exe. It simply fills the {compressor} with the name defined at the start of the entry.

{options} is where we pass our arguments at runtime. For example, if I used -moggre:s3, FA would translate the s3 to -s3 and use that parameter for oggre.exe.

thanks.. easy to follow.
I noticed when reading the "specific game" section they put up a series of commands. Using an example where in the command line is that inserted?

Is there a thread here that goes into more detail. I would like to explore this more in depth.

Thanks!

OK, One final Noob question

regarding the "specific game" section ??

What criteria is needed to determine which method to use.

Lets say for example I have a ton of wav files in a game, or lots of DDS files. What would I need to look for?

Thanks!

Please may you give an example of what you mean?

for wavs, use msc with tak plugin. For DDS, use srep then lolz.

Example: Yes
Here is a good page I think covers the information I am looking for

https://fileforums.com/showpost.php?...1&postcount=11

Which goes hand-in-hand with my question for the following you suggested:

for wavs, use msc with tak plugin. For DDS, use srep then lolz

How are these and what you suggested implemented?

Please keep in mind, that I am from the old BBS days where we ripped games in order to get them to make for a decent download on 9,600 - 14.4bps modems. So this method with arc is a little new to me after some 30yrs :-) (ok, Im an old fart)
