Dr Beep: probably You already know, but just in case: games for ZX81 have to be small, so there is no place for "Redefine" in 1K games. Instead people release several version (2 or so) with different sets of keys. Of course when time allows. I am rearranging the code and trying to find some room fo...

This is a super game - and not easy!

I want to play that with my joystick - can you change the keys to 5/6/7/8 ??

greetings

I will .... soon.

Hello Yerz, there is a distinct difference between a 1K game and a 1K RAM game. Storing a game in 1K and using 16K of memory is much easier than a full game in 1K RAM. My tribute this year will be some 1k Hiresgames in 1K RAM. I am already working on another approach of the limited screendata on a f...

No, you HAVE Hires! Use a 1K Zeddy (it's a 1K game!) and you have Hires: the 1K internal ram supports Hires ...

So Siggi , you confirm it runs on a unmodified ZX81 1K RAM?

no pun intended but... its amazing what can be squeezed into 1K when you put your mind to it. excellent work, have not tried it on a 'real' zeddy yet, but on the Eightyone the response to the keys seems a little fast and it can be difficult to stop at a junction. Regards Andy Andy, This is only the...

This version is slower.

True,
response is fast, but I can slow it down.

BTW, here is the code.

Hello, I made a 1K RAM HiRes game for the ZX81. "Wiwo Dido and the case of Mazeddy's Castle" During the search for Mazeddy's Castle Wiwo Dido fell through the roof and with his torch he must find 5 keys to get to the exit (set on the right). The found keys are displayed on top of the maze so you can...

Having seen WRX1K I was thinking of my own version of HiRes in 1K. A full screen game with a partial HiRes screen. By moving a HiRes character in a maze (the Wiwo Dido character from the case of the closing doors) you will move the displaying part of the maze too. In fact you walk in the dark and yo...

Oh man, how did I miss this? Instead of converting software, you can run it! Any 48K Speccy with an Interface 2 and a ZX81 emulator cartridge will do. A 128K +2A, +2B or +3 can also run ZX81 software without any additional hardware. Lookup Paul Farrow's website and you'll see. There is a topic on W...
