Spectrum Computing

This reminds me of the time I got in trouble in primary school. I was ALWAYS the good kid, but when the teacher asked "what were the causes of the Great Fire of London" my hand shot up & I couldn't resist the urge to say "it was because there was too much arson about" got a ...

Thanks, wondered if that was a false memory or not.

As a child I fast forwarded past those bits because they were slow.

Did elite nick it from 2001?

Thought I saw it in that film as well

It got great reviews and had two sequels but I remember them being bad games. Well programmed, but it was just negotiating a maze while jumping over most enemies. The environment was almost totally empty,no sense of progression,no upgrades. The combat for example. You have a side view so you can't m...

What is it

It's kinda pointless really but a good idea.

It doesn't actually work, but having the ability to rewind and reload would have been great

Thrust 2 has an interesting loader that loads the game in small chunks. It lets you rewind to load one that failed.

Unfortunately though it's buggy. Half the time the reloading fails and you have to start all over again.

Cool I'll try that.

Any chance of porting it to c64

It would be a first to have a language for both that is fast and efficient.

I have two rubber keyed spectrums. On one hardly any of my games load from tape. I hear the noises but most games don't display the yellow and blue loading stripes. The other spectrum loads most games first or second time. Does anyone know why this is? I think I heard that one revision doesn't need ...

I much prefer assembler, I had trouble even with the modern C compilers. There's a bit of work to get started, you have to get a font , write a print string function (unless you want to use the rom print) write a print byte function. Then you have to experiment a bit with dereferencing pointers in a...

Just loaded commando from tape successfully.

Hopefully that doesn't mean most of my tapes are too old to be read.

Has anyone observed what percentage of games load after 40 years?

the snake example is good, seems faster than if it were made in BASIC. Im trying to compile it using CYGWIN which is a bash shell in windows :) I tried doing sh compile.sh Game/snake but it said it couldnt find FIRST.M4 because it was looking in ../FIRST.M4 So I moved the compile.sh into the same fo...

I made a little 9v amp with a 555timer and a few caps that could I powered from a splitter cable off the PSU. Using that fixed all my woes! is that using an 80's tape recorder? or a modern one. My modern tape recorder works better when I lower the volume. When I play sound through the speaker on fu...

A lot of people suggested getting a stereo to mono cable. Cos I'm using a modern tape recorder which probably outputs a stereo signal.

Im going to try that, then if it doesnt work i'll buy an old school tape recorder that outputs mono.

Looks interesting thanks.
I'll have a go at it.

Is it possible to create a string,then reference it in different places in the code? (Like a string pointer)

Can I dereference a pointer? (As in store a 16bit address at a certain address....then retrieve a byte or two from that stored address)

Very enjoyable to watch thanks.

I had no idea the speccy was sold in other countries until after 2010-ish

Thanks it's worth a look . I suppose one way would be to project the computers car into the future if three different actions were taken and use the best. Although if the car crashed and was facing backwards it would need to do stuff which would seem bad to a short term prediction algorithm. So mayb...

I get that bullet code you write in regards to velocity but the other stuff goes over my head. I'd need to study normalise and dot product to really understand what's going on. Such a sin... d'ohhh And the TAN line :| Would it easy using this maths to get the computer to control a car on super sprin...

So doing it your way means you never have to deal with the threshold thing. Cos you are just checking for bigger than zero.
Sounds pretty good.

Oh that's cool that you have it done in blitz basic already. I don't remember exactly what I did but I wanted to know if the player was in a 90 degree sight cone of an enemy. So the enemy wouldn't see you unless he was pointing in the correct one of the four main directions ( as in up down left righ...

if each bullet was one pixel that would be easy to draw. It might provide a challenge...but I dont know how playable that would be overall. Are these 100 bullets going to come from a boss? if so, you'd have to decide are they going to shoot bullets out at the 8 traditional directions..or at every an...

has anyone loaded a game from an android phone (using playZX) to a real 48k spectrum?

I tried with all the settings and the sound turned up to 100% but got nothing.

A person would have to theorise how the program is going to work and then try it out. An a.i. is trying to emulate us. If chatgpt could access a zx spectrum emulator and type it in and see the results it would be useful. Chatgpt seems to be like someone who just comes up with the first answer they c...

Was there a reason to be disguised from humans?
