Release date: November 2014 Platform: zx spectrum Pouet: Full title: Wonderball (aka Happy Birthday Diver) Label: introspec & triebkraft Credits: introspec (design & code) key-jee^tbk (music) The running man animation was made using 12 frames of the video about Interactive Media Canvas “IRIS“ by HYBE (2012): Requirements: A ZX Spectrum with 128K of memory (or compatible) Stereo format: ABC Duration: 2:38 (looped) Contacts: zxintrospec@ Notes: Happy birthday, diver^4d! This demo is horrendously delayed and I won’t bore you with a range of convincing excuses that explain why it is so. Put simply, this seems to be the best (the quickest & the nicest) I can do at this stage. I hope you like it anyway! The code here is mostly original, although often suboptimal. My knowledge of monster^sage-style stack-based 8x8 chunk blitters comes mainly from the example coded for me last year by psndcj^tbk; many thanks for this mate, your help is hugely appreciated. Few things that I do with these chunks seem original to me, but I am sure there must be an ugly Russian demo from 1990s which does most of it in a frame :) The music player is interesting because this is the fastest player of compressed PSGs on ZX Spectrum (~450 t-states per frame on average, less than 1K t-states in the worst case scenario). The demo kernel is a slightly modified version of the kernel used earlier this year in “Down“; I first wrote it based upon the sources of the Triebkraft demo kernel by psndcj^tbk and jtn^4d, which were kindly given to me by psndcj^tbk. The kernel is using the ZX7 “mega“ decompression routine by Einar Saukas, with contributions from Urusergi and Team Bomba. Thanks: key-jee^tbk for allowing me to use your nice track, trefi^debris for his unhealthy facination with demo kernels, hacker vbi for his continued interest, optimism and enthusiasm, nyuk for “Zapilyator“ (TM), which proved to be extremely useful here ;) nq^skrju for regular sanity checks, diver^4d for the hexagonal gigascreen palette, which made my life much easier, and last, but not least, psndcj^tbk, for getting me into this mess in the first place!
