Re: Game of the day...

Beautifully smooth scrolling with no back buffer. The scenery is drawn directly to the screen via the stack. Very impressive. Multi directional scrolling at that and colours as well! Very impressive looking, will have to give it a go later. Thanks mate! :) You might want to grab my fixed version , ...

Re: Game of the day...

Was browsing through my collection sorting through Bleepload games (mostly, because I’d just figured out how to modify them and keep the loader intact), and found this gem: Soldier of Fortune https://spectrumcomputing.co.uk/SCRtoImage.php?SCR=pub/sinclair/screens/load/s/scr/SoldierOfFortune.scr http...

Re: Friday Quiz - backstories

I think 2 is too hard, so here's a bit more that at least hints at the game: Underneath this dead sun, beyond the surface lizards, beyond the tunnel of death, lay the biologic power generators of the evil Vard. The Vard, in all their hideous guises, had harnessed a colony of infant Zorr, and subjec...

Yep, thought Juan might have got that one.
I wouldn’t have known it if I hadn’t (upon request) made a couple of fixes for it. One of them was enabling the cheat mode, which revealed the “fall asleep in the 20th century” bit.

Re: Standard ROM entrypoints?

[Those tutorials you refer to, simply use a subset of “most commonly used shortcuts” to ease a novice into programming in languages other than Sinclair BASIC. Yes! This! This is exactly what I'm looking for! What are these shortcuts? Is there a known set of useful ones? What registers do they use? ...

Re: Standard ROM entrypoints?

I can infer pretty much everything I need from the above article, but it's far too fuzzy on things like which registers I need to preserve, stack status, etc. (e.g. which routines need the system variable pointer in IY? Does anything touch the alternate register set? Flags? Interrupts?) I was hopin...

Re: Standard ROM entrypoints?

What I’m still fuzzy about is this: “anybody whose tried to call BASIC from machine code will need to know this stuff.” I don’t know anybody who does this (aside from the people at Hisoft). The normal course of programming is to either ignore the ROM and system variables altogether, or to use a few...
