![]() ![]() The value contains information aboutthe speed of each song. SPEED= is a value in case insensitive hexa-decimal notation without aprefix. ![]() Itoften specifies the first song you would hear upon starting the program ishas been taken from. Thisvalue is meant as a proposal and is optional. is the decimal number of the song to be played by default. SONGS=, is the decimal number of songs (or sound effects) that can beinitialized by calling the init address. If so, the value in the bank-selectregister $01 determines whether the IRQ vector $0314/$0315 (Kernal-ROM on)or the IRQ vector $FFFE/$FFFF (Kernal-ROM off) is to be used. 0 means, theinitialization subroutine is expected to install an interrupt handler,which then calls the music player. is the start address of the machine code subroutine that canbe called frequently to produce a continuous sound. 0 means, the address is equal to theeffective load address. is the start address of the machine code subroutine thatinitializes a song by accepting the contents of the 8-bit 6510 Accumulatoras the song number parameter. Additionally, thoseextra bytes in the beginning can confuse disassemblers. This would create two redundant bytes if the C64data already had a load address in the first two bytes. Hence they move it infront of the C64 data. If the loadaddress is explicitly specified, some sidtune converters and utilitiesconjecture that the C64 data lacks its load address. ![]() Please don'texplicitly specify the load address unless required for sure. the first two bytes containthe little-endian load address (low byte, high byte). 0means, the data is in original C64 format, i.e. is the C64 memory location where to put the C64 data. C000 or E012, butneither $FCE2 nor 0xFCE2. ADDRESS=, , Each specified address is a 16-bit effective C64 memory location in caseinsensitive hexa-decimal notation without a prefix, e.g. It is structured like this: SIDPLAY INFOFILE ADDRESS=, , SONGS= SPEED= NAME= AUTHOR= COPYRIGHT= SIDSONG= The first line of the text containing ``SIDPLAY INFOFILE'' is only usedto identify the type of file. The SIDPLAY info file is derived from the information inside the PlaySIDone-file format. Notice that each pair of filesusually has the old DOS-naming of. This is a two-file format.A separate C64 binary data file is required. They can be convertedto a single file that contains a binary header. They are used to be able to alter theinformation inside with a normal ASCII text editor. However, they might have been renamed on other systems.SIDPLAY info files These are plain ASCII text files which have been introduced by theearlier versions of SIDPLAY/DOS. OnAmiga the corresponding C64 data files usually haven't had filenameextensions. A separate C64 binary data file is required. They have been used by PlaySID and aresupported by SIDPLAY. SID for additional infofiles.INFO files These are Amiga Workbench tooltype icons containing binary graphics dataand ASCII text information strings. Its main usehas been in assigning a unique file name extension to any sidtune file, butespecially raw C64 data files, and allowing to use. It has never been used to specify a file format. DAT file name extension has been introduced by the early versions ofSIDPLAY/DOS. SID) C64 Sidplayer format (.MUS) Raw data or PSID files have appeared as *.data, *.psid or psid.*.DAT files The.

It is recommended that you get accustomed to one-file sidtunes with the*.sid extension. A standalone C64 data file without a header or without acorresponding info file is considered invalid. That means,information like the memory location to load the file to, the number oftunes, the starting address of the executable code and its subroutines.This specific information has to be delivered in either a separate file -which is often called info file - or in form of a header in the singlebinary data file. ![]() Both, the programmer on the C64 and this emulator needinformation on how to access the code inside the binary file. *** SID/PSID (Various SIDPlay / PlaySID Emulator Formats)** Document revision 1.0 The data files used by SIDPLAY contain binary C64 data and music playermachine code. *** SID/PSID (Various SIDPlay / PlaySID Emulator Formats) ![]()
