Re: Berzerk for the ZX81

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.

Berzerk for the ZX81

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...

Re: ZX81 Berzerk Game

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...

ZX81 Berzerk Game

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...

Re: Merry Xmas and Happy Holidays

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.

Re: Reporting in from not so sunny Scotland

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.

Sudoku Solver

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...

Re: JetPac for the ZX81

The chroma interface uses the cursor keys as the joystick. So use the keyboard redefine option from the start menu and it will work with any joystick that uses the same ports as the keyboard. The redefine keys uses the ports directly so might work with other joysticks. Try it and see. Does it have j...

Re: Jetpac (Bukster) colour mod

The thrust trail was controlled by a routine I named Sparkles. The routine generated asterisks at the base of the rocket and scrolled down any existing sparkles. It was set to leave yellow paper colour behind it. So after a few sparkles have gone down, the whole trail is left yellow.

Re: Jetpac (Bukster) colour mod

Thanks for the feedback and effort. You did see that I've posted a version of JetPac that uses the Chroma interface on this forum? I see we've both used different colour schemes.
