3. System features

XBLD has the ability to write to CD-R discs and output files necessary for CD emulation. The functions of XBLD are shown below.

• Output of disc image for CD creation

• Outputting files for real-time emulation

• Output file for direct DOS file access

• Output file for on-the-fly writing

3.1 Outputting a disc image for CD creation

Outputs the DSK file (disc image) and TOC file required to create a CD.
The Line Once system uses the DSK file and TOC file output from XBLD to write to a CD-R disc.

1. This is the operating mode when the r, p, and oti subcommands are not specified.

2. Since the DSK file outputs the equivalent of VCDBUILD, it can be used with either ADDCDW or SEGACDW as a write-once system.

3. XBLD outputs TOC files in any operating mode.
   (There is no need to create a TOC file using VCDMKTOC)

3.2 Outputting files for real-time emulation

Outputs the files necessary to perform CD emulation in real-time emulation mode. (Real-time emulation is also possible for CDs that include complex sector arrangements such as channel interleaving, and CDs that require real-time processing such as MPEG functions.)

1. When performing real-time emulation, specify the "r subcommand" of XBLD.

2. A partial CD image update feature via VCDUTL is also available.

3.3 Outputting files for direct DOS file access

Outputs the files necessary for CD emulation using direct DOS file access. (In direct DOS file access mode, there is no need to create a disk image; the source file is edited into a sector image when CD emulation is executed. Therefore, it is not possible to emulate CDs that include heavy-duty interleaving functions, MPEG functions, etc.) )

1. When performing direct DOS file access, specify the XBLD "p subcommand".

3.4 Outputting files for on-the-fly writing

By linking with the write-once system "ADDCDW", you can perform on-the-fly writing.
On-the-fly burning does not require a disk image file, which saves time and hard disk space.
XBLD analyzes the disk structure from the script file and outputs SCT, PVD, OTI, and TOC files.
ADDCDW writes to a CD-R disc while creating a sector image of the disc from these files and the program/data source files.

1. When performing on-the-fly writing, specify the XBLD "oti subcommand".
