Re: 3-lace

A tip for viewing interlaced pictures, both standard and 3-lace: lower the contrast and brightness and the flickering will be reduced A LOT.

Re: 3-lace

I was secretly hoping I could use this for my next game and not bother developing my own hi-res code. If the 'none' mode was that, then it could save me a lot of bother. However, you say this isn't usable for games, so I'll keep looking for code examples and reading up on how it works so I can do i...

Re: 3-lace

I forgot to mention that it will most probably not work properly on any LCD-screens either. They will only work with standard 2-field interlace.

Re: 3-lace

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? Yes, the source is made in ZX-IDE (flat assembler), sorry I forgot to mention that. What do you mean by 'no...

3-lace

I happened to read a description of interlaced video (again) when it dawned on me that interlacing is simply an analog function of the TV synchronisation hardware. The way interlacing works is by delaying the start of VSYNC for half a line period, every other frame. The delay shifts the start of the...

Re: ZX81CRSS.ASM

Very nice way to save some bytes in 1k-mode, which is truly needed.

New year, new projects?

A new year is looming on the near horizon, and so I wonder if you have any SW projects that you plan on creating or releasing in 2019? Please share, entice and inspire! I have one recent almost finished project that only need documentation and packaging before release, very low level graphics in nat...

Re: Tapestry wide

Brilliant stuff indeed, Shame the humble zeddy doesn't have sprites... Imagine some awesome scrolling action games... Zedragon already uses this technique to a very good effect. I think a decent shoot-em-up would be possible, somewhere along the lines of R-type maybe? I won't do it though, not my c...
