Hi!
A few years ago we got some requests of the demo system we use in More Or Less Zero, Cernit Trandafir and so on.
Long overdue, we cleaned it up and made some template screens to try out. Not that we think many will need this today, of the few coders still out there most people probably have their own system anyways :)
But, for those who would like to try fullscreen, syncscroller, plasmas and other synclock effects, but has been put off by the rather high threshold, this could maybe be of use. Granted you know how to count cycles, it's pretty easy to make a multi-part demo with these kind of effects :)
Music players included:
- SNDH chipmusic (ST/STe/Falcon)
- YM3! chipmusic (ST/STe/Falcon)
- DMA-sequence (STe/Falcon)
- YM-8BIT digi-sequence (ST/STe)
- Lance Protracker (STe)
An example "demo" is included with templates for these base effects:
- 320x200 ST-LOW double buffered effects (ST/STe/Falcon)
- 320x200 ST-LOW tripple buffered effects (ST/STe/Falcon)
- 400x273 fullscreen (230 byte lw, ST/STe)
- 400x273 fullscreen (224 byte lw, STe)
- 320x265 screen with syncscrolling (ST/STe)
- 400x265 screen with syncscrolling (ST/STe)
- 320x199 Spectrum 512/4096 display (ST/STe)

PS. The syncscroller in the template is a 7-scanline one, there are more nifty ones out there, it's up to you to optimize if needed :)
