[ scenemarket – latest listings ] ORWO NP7/MA8

[Offer] Storage Media · Buy me a drink (by AMajesticSeaFlapFlap)

A number of respooled rolls of ORWO NP7 (tested to be around iso 125) and MA8 (slightly scratched, iso 3). The NP7 is very crunchy grainwise but aged well, like shooting photosensitive sandpaper. Some of these will have more character than others as they were decanted from daylight spools. Feel free to message me on discord for example images or development recipes.

[ Atariscne.org - News ] Rapido releases ST1 streaming depacker

Following Rapido's return to the Atari scene with the 2 releases at Sommarhack, he recently published his latest experiments in packing; https://github.com/odipar/ST1. Coded by Claude, directed by Rapido.   ST1 is a modified version of the well-known ZX1 packer by Emmanuel Marty, that incorporates a parameterized (fixed) window size for backreferences; which means that not the complete unpacked file requires to be available for depacking. ST1 provides both a packer (java/c# runtimes) and depacker (m68k). General usecase is (de)packing streams, which characteristic is that only a part of the compressed data is used per time; instead of the whole decompressed dataset.   I held a talk at Sommarhack this year about YM with timer playback using compressed streams; it has my interest and Im trying to find a somewhat generalized solution. I use (a slightly modified version of) tat's minymiser (https://github.com/tattlemuss/minymiser) to pack the bytestreams. Afterwards Rapido asked me for the sheets I presented. And a few weeks later (now), it with the release of ST1 there is an alternative choice for (de)compressing bytestreams. ST1 explicitly states it is inspired by minimyser.   Looking at the code; the main difference seems that ST1's context is a single, general purpose bytestream depacker, whereas minymiser is a complete solution interleaving depacking the different YM bytestreams into a single playback frame. So to use ST1 for YM playback, one should implement their own. So I did; 14 YM register streams, each individually packed. Depack 14 frames of complete YM data at init and then 14 bytes per frame for a single stream, cycling through the compressed streams each frame. Needless to say; it works :).   For a quick comparison purposes I ran 2 measurements, using the (timerless) YM3! dumps of Motus and Darwin's Dilemma end tune. On average, ST1 with ~1.08-1.21% cpu (~3.6 scanlines) per frame vs minymisers ~1.9-~2% cpu (~6.1 scanline).   spkr out.   🔗 Visit the Github repository of ST1
