(* Forbidden planet. Spectrum source... This code is (c) 1985..2008 Simon Brattel. All rights reserved, etc, etc, yada yada ya. Policy - to make the generated code as close as possible to the original release code. Therefore this source contains the original anti-piracy code, make sure the top bit of R is set. Or better yet, remove the test code (it is commented). This source is closer in form to the original and you'll need a competent assembler to assemble it. I've provided one at http://www.desdes.com/products/oldfiles/zeus.exe There were originally lots of separate sources, but I've stitched them together into this one to make life easier. One of the original sources has been lost, the one that had all the equates in it. Fortunately I've been able to recover those using a disassembler or to be more accurate I've recovered their values. Where these values were computed using expressions those have been lost. The formatting is very close to the original 1985 source, except for the loss of the original's use of 16-bit load pseudo-ops. In this code there are a lot of 16-bit loads to/from indexed variables. As a point of interest the original source had these as, say, ld hl,(ix+dObjepDraw) which looked a hell of a lot tidier than this. I removed them to make the source more compatible with standard assemblers, what I should have done is spent the time writing a better assembler... Done this now, wish I'd done it before I wasted a day chasing somebody else's problems :( Feel free to improve it, and send me anything interesting -> crem@desdes.com *) ; Assembly time options. Comment these out to make them ineffective ; These assume you've got an assembler that can cope with conditional assembly in ; Zeus's format. I'm afraid that this is very variable across assemblers... If you ; don't want to use Zeus and these options are giving you a pain then have a look at ; the "fp_spin.asm" source - I removed all trace of the conditionals from that. ;Original equ true ; Do the original Elephants equ true ; Elephants or Krell meters?
