Hi everyone.
As I said some time ago, I wanted to make a 'virtual' Sprite chip for the ZX spectrum, on my ZEsarUX emulator. The idea is to make some simple chip that maybe could be done in real hardware...
Link to a video demo:
https://www.youtube.com/watch?v=iaVkCzPHdOA
The main features of the video chip are:
-Sprite size 8x8 pixels, every pixel with a separate color of a 16 colour palette. This palette can be: standard ZX spectrum colour, or ulaplus palette, or spectra palette
-Every Sprite can be zoomed x2
-every Sprite can be mirrored horizontal or vertical
Every Sprite is shown over the main spectrum display.
-you can scroll the main video memory on each 4 directions. Scrolled is only done on pixels, not attributes yet
I hope you like it
Cheers
Cesar

Re: ZX spectrum Sprite chip
I attach some other video demos about the Sprite chip. They are date ordered, so I've been working on the Sprite chip these last days and every video shows a new feature added:

Re: ZX spectrum Sprite chip
Interesting - I wonder if it might be worth talking with Mark Smith on Facebook - he is making a replacement ULA for the Spectrum.
Whilst I appreciate that this is a software only solution at the moment, it might be that Mark could make some minor changes to his ULA PCB to allow the Sprite chip to be added at a later date if it got made into hardware...
I have pointed Mark at this forum post too

Thanks Rich. Mark has already told me about making some maybe limited version of this Sprite chip..RWAP wrote:Interesting - I wonder if it might be worth talking with Mark Smith on Facebook - he is making a replacement ULA for the Spectrum.

Hi
I have uloaded another video demo:

Showing sprite zoom, horizontal and vertical mirror, and some new Sonic movements
I hope you like it.
