- Mega Depack
- ===========
-
- Release 2.12
- ============
-
- Coded by Mike Watson
- ====================
-
- This version finished - 22/04/1993
- ==================================
-
- ------------------------------------------------------------------------------
-
- Written in 100% 68000 assembler, who needs compilers to do GEM based programs?

- ----------------------------- Shareware message ------------------------------
-
- All versions MEGA DEPACK from version 2.10 upwards are now SHAREWARE. The
- amount of work put into it and answering letters has meant I feel a small
- donation from anyone who uses it worthwhile.
-
- When registering please include an SAE/IRC's and a disk if you would like
- the lastest updates and/or any new projects I have planned.
-
- If you are unable to pay or you have written some nice pd/shareware then I
- always like receiving new s/w. Any FALCON stuff however will be most
- appreciated!!
-
- Any PD libraries are welcome to include this program in their catalogue. I
- would appreciate a shareware contribution or something similar (Floppyshop
- are always generous with free pd disks).
-
- If do disk based magazines then you may use this program.
- If you do then please send me a copy of the disk as you are getting it for
- nothing!!
-
- I still retain copywrite on my own source and the packer authors to theres.
- You may not modify,change or rip off any code without my prior permission
-
- Note - this documentation MUST be included with the program file if you do
- distribute it.
-
- ------------------------------- The legal bits -------------------------------
-
- This program has been tested as completely as possible and only makes legal
- system calls without any 'hacking around' and as such should not cause any
- damage. If for any reason damage is caused then I cannot be held for
- responsible for it. You use the program at you're own risk. To guard
- against any mishaps you should save the depacked files out as a different
- name or in a different folder.
-
- ------------------------------ How to use it ---------------------------------
-
- Firstly decide on how you wish to use the program, Mega Depack 2 can run as an
- accessory or a program.
-
- TO RUN AS AN ACCESSORY
- ======================
- Rename it as MEGA_DP2.ACC and copy it into the root directory of your boot
- disk. MEGA_DP2.RSC must also be present in the same directory.
-
- TO RUN AS A PROGRAM
- ===================
- Leave it as MEGA_DP2.PRG and copy it where you like. DO NOT copy it into the
- auto folder because it uses GEM which is not initialised until after the auto
- folder programs have been run.
-
- NEW OPTION
- ==========
- As from version 2.10 MEGA DEPACK will now accept simple parameters on the
- command line. You may either specify a single filename or a directory.
- In either case the unpacked files will overwrite the packed ones and any disk
- or memory errors will be ignored.
-
- Owners of machines with TOS v2 or greater can drag the program onto the
- desktop and then directories or files can simply be dragged to it. If doing
- this then you must set the default directory as APPLICATION and the PATH must
- be the FULL PATH. This has also been tested with TERADESK and seems to work
- so i see no reason why it shouldn't work with other deplacement desktops.
-
- The command line has been tested on TOS v4.0 (on my FALCON030!).
-
- Please remember that it is a simple commandline so please don't upset it too
- much! I wouldn't trust it past *.* or single filenames in fact!!
-
- LOADING
- =======
- To load in a file for unpacking click on the LOAD button. A fileselector will
- appear and you can select a file for unpacking. The file will then be loaded
- and an attempt will be made to unpack it. If a successful attempt is made then
- the SAVE button will be made selectable.
-
- SAVING
- ======
- Clicking on the save button will bring up a file selector where you can select
- the file to save to. Clicking on cancel will abort the save process.
-
- BATCH
- =====
- Next up is the batch option. Click on the BATCH button and the option to do a
- RECURSIVE or normal batch mode will be given.
-
- RECURSIVE batch will search all sub directories whilst a normal batch will
- only do the files in the selected directory.
-
- After this a file selector will appear, select the path that the files will be
- loaded from.
-
- A new file selector will now appear, this time select the destination path
- where the files will be saved to. If you select cancel then the load path will
- be used. After this the files will be loaded,depacked and saved to the
- destination.
-
- SPECIALS
- ========
- There are some files which cannot be easily recognised and require the user to
- decide themselves on how to unpack it.
-
- The clashes are - ice 2.0 and 2.2 have header Ice!.
- all pompey datafiles have trailer POPI.
- atom v3.1,3.3 and thunder 1,2 all have header ATOM.
-
- When this occurs you are given a choice of depackers to use or a chance to
- exit. Choose what you think is the right depacker. It will more than likely
- crash or produce garbage if it is the wrong choice so save it out as a
- different file name and check it. If something is wrong then try again with
- another option.
-
- HELP
- ====
- Help on the packers supported and on how to use the functions is available
- here.
-
- -------------------------------- Extra bits ----------------------------------
-
- A new feature of v2 is the ability to recognise several popular file formats.
- Some may be packed others may not but mega depack2 will reccommend a package
- to view/use/depack the file.
-
- The current files recognised are LHARC, ARC, ZOO, PK ZIP, IFF, DEGAS unpacked,
- NEO pics, NEO animation object files.
-
- If MEGA DEPACK 2 cannot depack a file but suspects that it may have been
- packed then please send it to me. If you have written a new packer then I
- would also like to receive it.
-
- Ways to spot packed files :-
- Mega depack may say that it could be packed.
- The file was packed by yourself.
- It displays a mesage when loaded e.g 'blah packer v555555 depacking'.
- Flashes the colours in a hypnotic fashion.
-
- -------------------------- Future enhancements -------------------------------
-
- Future enhancements to this program are :-
-
- Use of similer techniques employed by the 'naughty' unpacker to try to
- unpack unknown program types - MAYBE!!
-
- Multi task properly in MULTITOS. It runs but doesn't multitask.
- Will be a pain actually - memory problems trying to allocate ram for
- depacking files.

- ----------------------------- History for v2 ---------------------------------
-
- VERSION 2 (beta) completed on 29/09/1992.
-
- VERSION 2 release completed on 11/10/1992
-
- VERSION 2.01 release completed on 23/11/1992. Updated for speed packer 3.
- Nice packer, strange way of saving out files. Its exec files don't have a
- depacker. You have to use a supplied prog which locks into the trap 1 vector.
- The first line of the packed file is a trap 1 statement and its this that
- triggers off the depacker.
-
- VERSION 2.02 completed on 28/11/1992
-
- VERSION 2.10 completed on 10/02/1993
- This is the biggest upgrade since v2.
- Fully tested with TOS v4.0(FALCON tos) and I think I've uncovered another
- bug in the ROM when doing so!!
- Updated for recursive batch mode. Wow at last a use for the LINK instruction!!
- Updated for handling command lines.
- Updated to change 4PAK recognition as certain C compilers produced the same
- bytes in the header that I was checking for.
- Updated for Atom v3.3b program files.
- Updated for powerpacker files.
-
- VERSION 2.11 completed on 23/02/93
- Updated for SUPER PACKER 3.
- Fixed FALCON bug (hopefully, was caused by GEMDOS finding memory for small
- files that expanded well out of that range.)
- Updated for the current release of Rob Northerns packer.
- Rewrote recursive batch mode and dispensed with LINK method.
-
- VERSION 2.12 completed on 22/04/93
- Updated for Grazey's version of Speedpacker3.
- Updated for another unknown packer.
- Updated Atomic 3.5 check because people tend to edit the text I was
- checking against.

-
- SINISTER DEVELOPMENTS are a group of computer enthusiasts who aim to
- produce top quality software for the ATARI ST/E/FALCON and AMIGA computers.
-
- All of it so far has been shareware or PD but who knows what the future may
- bring!!
-
- Here is a list of what we have done:-
-
- If you want any of these productions then send a cheque for £5 made payable
- to SINISTER DEVELOPMENTS and state your choice of game.
-
- 1) ASTEROIDS
-
- Our first ever production. Featured in PUBLIC DOMAIN and on the ST REVIEW
- coverdisk. The best conversion of ASTEROIDS on the ST (modest (huh?)).
- Full 50 frames a second gameplay in MONO and COLOUR flavours and possibly
- more fudged code than you can shake a stick at but a great game.
-
- 2) CENTIPEDE
-
- The follow up to ASTEROIDS and featured on the ST FORMAT coverdisk. A
- great version of the classic ATARI shoot 'em up with more than a hint of
- MILLIPEDE to it. Super smooth 50hz action and quite a high FUDGE amount
- too!!
-
- 3) GALAXIANS
-
- Our latest release. A coin op conversion that isn't based on an ATARI
- design!! Another classic conversion that does it at 50hz!! No comment on
- the game that took it's place on the ST FORMAT coverdisk.
-
- 4) ASTEROIDS - AMIGA
-
- Our first AMIGA production!! OVERSCAN and sampled sound effects to full
- effect!!.
-
- 5) A new utility to make MULTITOS look more like windows!! And will be of
- use to everyone!!
-
- 6) I suspect that centipede and galaxians may be ported to the AMIGA.
-
- 7) The same does not hold true for the FALCON, I have something MUCH more
- special planned in the FALCON games dept (admittedly not as good as some
- of the stuff I saw the other week but then I don't have any mad friends
- who do 3d for breakfast!!).
-
- 8) Anyone for ASTEROIDS for the PC ?????
