Title: PCE Slideshow: OLD IS BEAUTIFUL
Post by: ccovell on February 21, 2016, 01:13:18 AM
Hi, everyone. I attended the 2nd day of the Tokyo Demo Fest this year, and entered a PCE slideshow in the Wild compo. (Placed 5th, but at least I got to meet and chat with some fun, interesting people.)
You can check out a high-quality(?) composite video capture of my demo here:
No raster-graphics-splits or flickering is used to display the pictures in the demo.
I'd bet that people were surprised to see a PC Engine at the Demo Fest.
Thanks!
The organizers were happy/intrigued, but a random sampling of guests kinda proved an earlier statement of punkfloyd's about their PCE/SGX demos: nobody really knows what the PCE is ("Is it a graphics card for the PC?", I heard) nor what it is capable or incapable of. I love the demoscene but it is often removed from the retro gaming scene, as I'd call it.
Anyway, here's a little explanation of the "hicolour" effects in the slideshow: (http://chrismcovell.com/images/OldIsBeautiful_expl.jpg)
The added benefit is that you can devote an entire colour channel (red, or cyan if you want) to one layer (sprites or SGX BG...) and the remaining channels to the standard BG. This means more & a greater variety of colours together in a confined space, with no attribute clash. Hopefully.
A test of this is here: http://chrismcovell.com/data/OldIsBeaut-Test.zip I and II change palettes.

chris,i saw in your demo that you used a $200 bytes tia for updating your satb in vram, and this do not cause any problems with sample playback because of block transfert instructions cannot be alted ??

Generally, all my sprite definitions are set up at the start of the demo, and then never touched (ie: TIA not used) throughout it. I do use Sprite 0 for the moving HiChew, but that is far less data. (It also coincidentally is moved around when music is not playing anyway.)

Chris, you are a master. If this can be done somehow in HuC, it'd be great because newbies would be able to pick up on it and use its new code. As it is, the fact that you included the source is enough for people to learn from. You knocked this out of the ballpark.
