1 - Disclaimer
This program is copyright 1995 by Nowak Christophe.
It's freeware. You can use it, spread it, as long as you
don't ask money for it and don't modify it.
It can be spread with Prowizard and ExoticRipper.
Remember to register to these products if you use them.
This software is provided "as is" without any warranty, either
expressed or implied. By using this software, you accept the entire
risk as to its quality and performance.
2 - Introduction
This little program enables you to search for crunched datas
inside a file with the help of the XfdMaster library.
The first aim was to be able to search for crunched datas on
a disk more easily.
When a cruncher is found, you can save the crunched file or
decrunch and save it.
I wrote this little tool to help me to find music modules in
demos or games. Remember, when you get a module, don't forget
to put the author's name in the module if it's not present.
3 - Requirements
- 1 Amiga
- Xfdmaster library from Georg Hörmann
The program was tested on :
- A4030/2 chip/4 fast
- A1200/2 chip
I don't know if there are enforcer hits.
I think it should work on all 'not so old' amigas.
4 - Description
For now, the program can only be launched from CLI and accept
no parameters (i want to make a GUI but i'm doing my
military time now, but i hope to put some asl requesters soon).
After launching the program, it will ask you a filename.
Enter the name of the file you want to search into.
The program will load the file in memory and begin to search for
crunched datas.
When it finds one, a message will be printed :
name of the cruncher found
(S)ave crunched data, (D)ecrunch data, (C)ontinue search, (E)xit
if you enter :
- S : the crunched file will be save from its beginning to the
end of the loaded file.
- D : the program will try to decrunch the datas. If it works,
you will be asked to enter a save name for the decrunched
datas. If it fails (not enough memory, corrupted datas,...),
you will be able to save the packed datas.
- C : the program will continue the search.
- E : the program will end.
A search can be stopped by pressing on the left mouse button.
(WARNING : The mouse test button is very bad code so it is not
multitask at all. May be a better code later or use the MUI version.
If somebody can send me a good mouse test in ASM i'll be very happy)
WARNING :
- PowerPacker Datas can not be decrunch because of the file
format of the packer.
- the xfdmaster library finds lots of DragPack 5.52 datas.
Most of the time, they aren't.

6 - To Do
- GUI (perhaps with MUI) but soon, i hope, asl requesters
- gain some speed (i'm not a good Asm coder)
- parameters when launched from CLI
- more information like size of the decrunch datas, decrunch
errors, etc...
7 - History
1.0 (26-feb-95) : first public version
only speed improvement (lots of speed).
Thanks to my brother Olivier.
0.9 (5-Jan-95) : internal release
first useable version but very, very slow.
(about 5 mn for a 80 ko file, arghhh!!).
