Spectrum Computing

So out of interest I looked at the Maziacs one. That's a little delay routine. He PUSHes BC to the stack, loads BC with 100, pushes BC to the stack AGAIN, then puts 0 into BC, and does a DJNZ, then POP BC, DJNZ, POP BC, Return. A delay loop. POKEing replaces the first instruction with RETurn so you ...

They're both Z80 machines so that's good. But the memory address of the screen is going to different, also ROM calls and that. So as usual "it depends"

Would looking at ERRSP help at all?

Expanded a bit. There is another Tripod terror game on the Spectrum other than War Of The Worlds and The Tripods. WotW ist listed as an inspiration on the game details page, but isn't available in the search list on the home screen. Am I really the only one with a liking for sub-Viking Raiders basi...

Obscure clues and verb-guessing frustration was the inspiration for my cgc entry last year, which I feel had outrageously specific commands, but presented such that anyone can complete it easily. Play it now! https://spectrumcomputing.co.uk/entry/38128/ZX-Spectrum/The_Da_Vinci_Code_2_Trouble_From_T...

All that joystick waggling has caught up with me...

Interesting! Perhaps there's a bit of lag on my end or something!

I didn't see Barbarian: the Ultimate Warrior or Barbarian 2 in that list or in the search for posters.

The first has a Magazine Poster though. I'm convinced the second one had a poster in the box (but then again, I just remember the advert....)

I think I got the General from the Home Computer Club, so a little cheaper. It's an interesting game, and at least you can't just break in to it... effort there. Some stuff put at ERRSP I think.

The General was very good (apart from a bug that I fixed). There is a small piece of machine code for a sound-effect and to stop you pressing BREAK, but that's about it. I was surprised to find it was BASIC after it crashed...

I just played Mission 1 (and managed to soft lock it, so completed it by cheating). Some interesting ideas but a bit dull.

You can't break in to the BASIC code. Or you can but it then instantly goes CONTINUE. 77 bytes of M/C and also line 1 of the program looks a bit weird/REM statement-y.

I think it was better when they had the hex dump AND the assembly listing. I typed in some machine code for a game and it just didn't work because it was wrong. Knowing what the numbers meant AND what the author was trying to do, it was easy to fix. But just numbers? And without a checksum? No chance.

Incredible sir. Yep that's the one, and Turtle has been inputted faithfully without modding, so that can be archived as the one. The SQL will be queued. I just typed it in too (and submitted). There are some bits where the printing has clearly gone a bit dodgy so I corrected those in my version to ...

Ace! How did you remember?! The game is not even yet in the SC database :) https://ia600604.us.archive.org/view_archive.php?archive=/1/items/World_of_Spectrum_June_2017_Mirror/World%20of%20Spectrum%20June%202017%20Mirror.zip&file=World%20of%20Spectrum%20June%202017%20Mirror/sinclair/books/123/1...

"Turtle" looks identical to "Turtle Bridge" which is chapter 4 of Richard G Hurley's "15 Graphic Games for the Spectrum", Micro Press, 1983. Especially if line 1 is a REM statement with mchine code in it.

Celtic Carnage.

There's O'Brian. https://spectrumcomputing.co.uk/entry/1 ... rum/OBrian A bit tenuous... as were Agent Orange and the Munsters.

Snake Pit by Mike Singleton?

There was Slaine, of course.And a text adventure I played on stream once, you had time travelled to mythic Ireland. When I remember the title I'll pop it in here.

The key is white light, and lots of it. I have white lightbulbs too. Try it with yellow lightbulbs and you're in for a world of hurt...

I have distant memories of my brother and I taking turns to type in one of the longer listings, but accidentally ended up saving it to tape incorrectly, and having to give up on the program because neither of us were willing to start from scratch. I haven't watched the full video yet but scanning o...

Only the best would do for Mike Singleton! He does tell you to do stuff that doesn't quite work. Save the location DATA to tape and then LOAD it doesn't QUITE work, as he used Z$ as part of the "building the flag" string, which happens AFTER the location stuff. So in my code you start, jum...

1984 type-in from the late, great, Mike Singleton. A bit of a boardgame/computer game hybrid, with the Spectrum being the "umpire". And I act out parts. And look at how the music works. And make some possible improvements!

Although 16-bit computers were available by the time I got my ZX Spectrum +2 (in 1987 I think), they were still a lot more expensive. That's why I stuck with the ZX Spectrum... and we went for a SEGA Master System instead of the Mega Drive. Just like the Commodore 64 had certain advantages over our ...

On my old PC I typed in an audio sampler and was able to shout into the microphone and the Spectrum picked it up (via "load from audio source" in Spectaculator.) So it was possible. When I try on my new PC though, it never picks up any sound though. It's how I did the "I am the God of...

I quite liked the ZIP Compiler, which was written originally as a type-in. It turns Sinclair BASIC into machine code which is a lot faster (but not as fast as pure machine code). Astonishing achievement. But more modern stuff exists, like ZXBasic that you write in just about BASIC and compiles strai...

It's always lovely seeing new people getting the "I want to create something" bug!
