Sinclair ZX80 / ZX81 / Z88 Forums

Yes, the source is made in ZX-IDE (flat assembler), sorry I forgot to mention that. What do you mean by 'none'? The simple stair-step pattern is made in WRX mode, I was too lazy to make source for pseudo-hires. This is only a quick proof of concept. I was secretly hoping I could use this for my nex...

Thanks for the source code. I've been able to compile it with Flat Assembler. As you predicted, it does not work with an emulator.

So I take it the 'none' mode is just straight pseudo hi-res?

I've just uploaded a version of the game Berzerk where the screen scrolls when you exit so I have already written scroll up, down, right and left scroll routines. They are for the entire screen, but could be easily modified. Have a look at the video if you like and see if the scrolling is smooth eno...

Thanks,

Try this link for an MP3 file. This will run on both a standard 16k ZX81 or one with a Chroma interface.

It's a personal rule I have that everything I program must run on the original hardware.

I've uploaded a final version of ZX81 Berzerk. So it looks like it's the last game of 2018 rather than the first of 2019 to be published. The final version features eight mazes. I've added difficulty levels that mimic the way levels went up in the original game. Robots do not shoot at first, but thi...

It's probably blasphemy to program on Christmas. However, I have managed to get the robots to fire on the diagonals. The aim isn't perfect, but its good enough to keep any player on their toes. I've also put in difficulty levels. The original game became more difficult as the stages increased, shoul...

I've got the ZX81 Berzerk clone to the point where I think it's fit to give you all a Beta version of a new game to play just in time for Christmas. I'm a day ahead of most of you here in New Zealand. For me Christmas is tomorrow. I any case, here is the first version of ZX81 Berzerk. There are stil...

Will do. It may be the height on summer here in New Zealand, but the weather is still horrible. This does mean I've had time for more ZX81 programming as I'm not at work.

No so sunny here in New Zealand either. It's the first days of summer and everything is soaked after weeks of rain. At least this weekend has been nice.

I read an algorithm to solve Sudoku a few weeks ago and couldn't resist having a go at programming it. I see somebody else has already done a much better version with sudoku generation and many other features. So I'm not the first, but here's my effort. Type in your clue numbers (displayed in invers...
