Detailed Description

Shared music data for Castle Master backported music players.

Song data extracted from the default subtune in the C64 PSID. The order lists are expanded from the original repeat commands, while the pattern data remains in the original note/rest/instrument command format.

Shared music data for Total Eclipse backported music players.

Song data extracted from the C64 version's Wally Beben music engine. The shared instrument table strips SID-only pulse-width fields, but the original pulse-width values are kept below for ports that can use them. This header is included by both the AY and OPL player implementations.

Function Documentation

◆ makeWallyBebenStream()

Audio::AudioStream* Freescape::makeWallyBebenStream ( const byte *  data,
uint32  dataSize,
int  songNum = 1,
int  rate = 44100,
bool  stereo = true,
const WBTableOffsets *  offsets = nullptr 
)

Create a music stream for the Wally Beben custom music engine used in the Amiga versions of Dark Side and Total Eclipse.

Parameters
dataRaw TEXT segment data (after 0x1C GEMDOS header)
dataSizeSize of the TEXT segment
songNumSong number to play (1 or 2)
rateOutput sample rate
stereoWhether to produce stereo output
offsetsTable offsets (nullptr = Dark Side defaults)
Returns
A new AudioStream, or nullptr on error
