Re: Easier graphics on zx spectrum
Men take only their needs into consideration - never their abilities. Napoleon Bonaparte Look there is no square-space for spectrum game development. If there were such a thing people would be churning out fappy bird clones on a daily basis. :lol: You got to put some effort into this, invest some t...

Re: Crashing a program with DFSZ pokes.
More interesting developments, the version of the manual that Trade Secret is referencing is the revision one. It was a little unclear what version was being used. This has now been resolved. Big thanks to PeterJ for the assist. You might be thinking 'well so what?' it clears up a question of attrib...

It is a very optimistic advert. It assumes a working understanding of BASIC & Maths. :lol: In an age where we now do the opposite and assume our audience are windowlickers it is rather jarring to see these kind of things :lol: no thought was given to the readers that today would be 'triggered' b...

Re: The Definitive Programmer’s Guide to Using the Floating Bus Trick on the ZX Spectrum
True it depends what you compare it against, I would compare it against something like altirra. One guy in college wrote probably one of the best Atari emulators and what many consider to be one of the best 8-bit emulators while he was in college :lol: The documentation is some of the best I have se...

Yea you are right about wrong dates being entered into the meta data. For example INPUT gets listed as being published in the 90s..

Re: Crashing a program with DFSZ pokes.
Yea, that is also in Trade secret. But this article pre-dates the publication. See I am starting to get the impression that Trade Secret was a combination of techniques from letters/articles that were published in newsletters/magazines. *put on tin foil hat* Perhaps that's why it never got a review ...

This is fantastic having multiple sources for the same technique helps a lot in documenting the technique. It is also useful in figuring out stuff like where a technique first emerged from. The article you link is December 1984, Trade Secret was published some time in 1984. It makes me wonder if the...

Re: Crashing a program with DFSZ pokes.
I don't know much about the RANDOMIZE USR 0 trick other than it was a way to fake microdrive support on a system that didn't have it? My understanding is, its for BASIC use. By forcing the error output to have nowhere to print it triggers the crash. This is what Trade Secret says In BASIC programs, ...

Re: The Definitive Programmer’s Guide to Using the Floating Bus Trick on the ZX Spectrum
One thing that should make everyone uncomfortable.. This is just one un-implemented behavior of a core system. How many more behaviors are left unimplemented by emulators on core/primary systems they are presenting as accurate. Now consider that many of these same emulators have had continuous devel...

Crashing a program with DFSZ pokes.
Figured it was only fair to share and get some feedback. Trade Secret talks about a method to cause a program to completely reset the machine on quit, no dumping the user back to the BASIC interpreter. 10 BORDER 1 : POKE 23659,0 : POKE 23658,8 20 FOR I = 1 TO 24 30 PRINT I 40 NEXT I 50 IF INKEY$ = &...
