If CIA, then the CIA 1 timer A cycle count defaults to its PAL or NTSC KERNAL bootup settings. For PSID files, the VBI must trigger at some raster value less than 256, while RSID is supposed to only use raster 311. It either specifies using VBI (Vertical Blank Interrupt), declaring that a raster interrupt will call the play routine once per frame, or a CIA (Complex Interface Adapter) timer interrupt, which can give easier control over how often the play routine is called per frame. The SID file headers contain a set of “speed” flags, that indicate by which kind of interrupt a particular subtune should have its play routine invoked. The more frequently the play routine is called, the faster the song plays back. The play routine is called by the SID player at regular intervals determined by an interrupt. The Commodore-native payload must contain an initialization entry point and a play routine entry point. (It’s actually quite impressive that this level of generality can be brought to bear on arbitrarily-crafted C64 music code, so hats off to the HVSC team for having normalized the playback experience of tens of thousands of Commodore music programs). As of release #72 of the High Voltage SID Collection, the set contains 49,119 PSIDs and 3,208 RSID riles, of which 495 of the RSID files are written in BASIC.

PSIDs can play back on low-fidelity emulation, while an RSID requires anywhere from a low-fidelity emulation to a full C64 emulator to play back correctly. Under the covers, each SID file contains either a PSID (“PlaySID”) or RSID (“Real SID”) payload. To play SID music, 6502 machine language emulation is required. Nearly all Commodore games have had their music preserved in SID files, and the format is how contemporary C64 music is exchanged today.

SID files often contain subtunes, which are a collection of tunes that usually share the same playback engine, “instruments”, and reusable patterns of musical notes.Ī variety of SID file players have been developed over the years, from native C64 implementations to playback on one’s Android phone.

This should not be confused with the “SID” (6581/8580 Sound Interface Device) sound chip used in the Commodore 64, 128, MAX, and CBM-II computers.Ī SID file contains a Commodore-native-code payload that plays music, along with headers that describe how to execute the payload. Try out the search box in the top right corner, or check out the CSDb main page for the latest additions.The term “SID” is commonly used to refer to a file containing Commodore 64 music.

Great, thanks a lot for maintaining this fantastic tool! And now a Covert Bitops Loader update with Exomizer 3, please :-)!ĬSDb (Commodore 64 Scene Database) is a website which goal is to gather as much information and material about the sceneĪround the commodore 64 computer - the worlds most popular home computer throughout time.

Unfortunately my ambitions to properly implement my colorscheme idea are kind of lost on my 'eternal ToDo list' atm. Submitted by spider-j on 2 September 2018Ĭool, nice you implemented that. Will push fix to svn, you can get it from there and compile yourself.Ĭheers for the updated version! Perhaps the bug-report (e-mail, ) I sent you regarding the filtermode in the tracker (but luckily not the player) could be fixed sometime in the future too? :)Įxelent!, im use it from the begining, thanks Looking at the bug now, it's an obvious copy-paste error.
