Re: Gamecoding in machinecode on a ZX81.
First, thanks a lot to Dr Beep for this nice tutorial. My comment refers to chapter 6 of the tutorial. The random routine is not random on a ZX81 simulator (I tested with EightyOne and ZEsarUX). My simple explanation (correct me if I'm wrong) is that every time you load the file, the sequence is ide...

Re: ZX-IDE Tutorial for programming assembler and ZX BASIC
Good afternoon, Happy new year to the SINCLAIR ZX WORLD community. It was asked a few times already, but I thought I would give it another try for the new year: @PokeMon, would that be possible to publish the source code for the ZX-IDE? I'm running into problems with using wine on my LINUX machine (...

Re: SHROOMS - New 16K ZX81 game
I was a bit worried after 'Bob's 8 bit blog' went silent... I'm glad to see that BOB IS BACK :-) @Bob, in the spirit of the 8-bit blog you started some years ago, would you consider publishing the source code of your game with some explanation? That would probably be the best way I could learn from ...

Re: ZEsarUX-7.1
Hi Cesar, thanks for the great work, I appreciate being able to use an emulator directly from my linux machine without the hassle of Wine or VirtualBox... Question (not related to 7.1): I'm trying to run Celebration and Against The Elements, from Paul @ fruitcake.com. The graphics are hires, but the...

Re: Smooth horizontal scrolling
Hi Lardo, Thanks a bunch for your suggestion. I started to play around with your program, and wanted to get back to BASIC, so I made the following change: - jr mainLoop + ld a, 0 + in a, (254) + cpl + and %00011111 + jp z, mainLoop + ret so that I could get back to BASIC when a key is hit (keyboard ...

Smooth horizontal scrolling
Good morning, I'm trying to do a smooth horizontal scrolling while developping a small game. The image is low-res graphic chars, and I want to shift line 16 to 24 from right to left smoothly. As can be seen in the attached file (zipped avi), this is far from smooth. UnsmoothHorizontalScrolling.zip C...

Re: PONG with AI clone ?
@Dr Beep, you're right, hi-res is plain ZX81. For what I'm intrested in for now, low-res is better, that's all i meant.
@Moggy , thanks a lot, i tried TENNIS, and it is a PONG clone with AI !!! And it is fast.

PONG with AI clone ?
Good evening,
Might sound like a silly question, but I could not find an answer on Google or the forum: is there any PONG clone on ZX81? And if so, is there an "AI" you can play against?
Thanks. Bruno.
Note: i'm not talking about high-res, but a plain ZX81 game.

Re: ZX-IDE Tutorial for programming assembler and ZX BASIC
I found the reason. It's an extended ASCII code (F7 in my case) that creates the issue.

Viewing issue with ZX-IDE
Good evening, I've had this issue for some time, and was not able to fix it. One of my programs opens as shown here: ZX-IDE-screenshot.png making it impossible to properly use. I have no clue what the reason is. I opened the file in Notepad++, looking for hidden char that could trigger this, without...
