Bitbuster v1.2 - (c) 2002-2003 Team Bomba
|
|
------------------------------------------
|
|
|
|
|
|
Bitbuster is a new set of (de)compression-tools for MSX and PC. It was created because I was getting frustrated by POPCOM; it made crash Bombaman. That's why Bitbuster was created.

|
|
Bitbuster vs POPCOM
|
|
-------------------
|
|
Bitbuster looks a lot like POPCOM, they both use a similar compression scheme. The compression ratio is pretty much the same, sometimes bitbuster is better than popcom and vice versa. Here's a little comparison (files mostly taken from Bombaman). The lengths stated for POPCOM are the lengths of the compressed data without decompression code.

How to use Bitbuster packer
|
|
--------------------------
|
|
To compress a file, simply type the following on the commandline:
|
|
pack <sourcefile> [sourcefile1] ...
|
|
This will compress all specified files. You can also use wildcards in filenames. The new files will get the extension .pck.
|
|
|
|
|
|
How to use Bitbuster depacker (executables)
|
|
-----------------------------
|
|
To decompress a file (on PC), simple type the following on the commandline:
|
|
depack <sourcefile> <destfile>
|
|
This will decrunch sourcefile and write the original data to destfile.
|
|
