- QUADRIX © Geoffrey Sparks 1991/92.
- -----------------------------------
-
-
-
- QUADRIX is Shareware. This demo version featuring 50 levels can be
- freely distibuted as long as all files are included and no material is
- altered in any way. A reasonable fee may be charged for copying in line
- with the standard set by most PD libraries.
- The game concept, graphics, code etc may not be altered or duplicated
- in any way except as above.
-
- WARNING: Quadrix is currently (Feb. 1992) PAL only. I make no claims
- for its appearance on NTSC machines, (sorry).
-
- OK.... So you've played the game and had a bit of fun. Well now
- things get serious. For the princely sum of $20 Australian dollars,
- ( sort of like play money really! ), you can become a registered user
- of QUADRIX. On receipt of your cash ( international money order, cheque
- drawn on a bank with Australian offices etc. ) you will be rushed by
- air-mail the very latest version of Quadrix... including...
-
-
- 1. 100 new and perplexing levels, taking off from where you should
- have finished in the demo version.
-
- 2. A complete, easy to use level designer. Create new levels and
- amaze your friends...( amaze yourself!! ). Good fun.
- Full instructions included.
-
- 3. All the source code you could ever need. Thats right! The
- complete, unexpurgated story of one puzzle game's struggle to
- be born. Occassionally annotated, often amusing and
- frequently revealing. Many hints and tips for using AMOS and
- how to combine a bit of assembly language when needed. Over
- 35 pages in all - an offer too good to refuse.
-
- 4. Peace of mind. Well if you play the game a lot you should
- really fork out the asking price.
-
- 5. Code word to allow the sub-game to be played as a separate
- game.
-
- 6. Possible discounts on any other games I write - ( well I
- havent actually got as far as a sequel yet - but if this
- does well ... who knows.)

- HISTORY.
-
- Quadrix was originally conceived and written on the C64 a
- couple of years ago, with a slightly different format and minus the
- sub-game.
- With the purchase of an Amiga and a copy of AMOS, along with
- several technical manuals and a copy of the PD A68K assembler, work
- started on upgrading to the 16 bit world. Along the way I learnt a lot
- about the AMIGA, AMOS, 68000 machine code, Deluxe Paint, MED and
- most of all memory management - getting Quadrix to run in 512K was
- some task.
- This version was completed around the beginning of 1992, about
- 6 months after deciding to re-write it for the AMIGA.
-
-
-
- THANKS.
-
- Many thanks to Jan Clark for loads of play testing and lots of
- extra levels, as well as innumerable helpful suggestions and advice.
-
-
- TECHNICAL STUFF.
-
- Quadrix was written on an off the shelf, department store A500,
- with a ram expansion card [ includes clock! ], and an extra floppy
- drive, ( I hope this isn't too technical for you.). The language was AMOS,
- compiled with the AMOS compiler. Machine code was written using MEmacs,
- assembled with A68K, and linked with Blink.
- No hard drives, cross-assemblers, accelerators, esoteric compilers,
- IBM's, MAC's, Amiga 3000's, Devpacs, Lattices or trick photography was
- used at any point.
