Using ROFS, you will get a flexible and high performance file management system.
Free from Limitations on File
System
Some file systems for game consoles have various limitations,
such as the file name format (8.3 convention), the number of files, and
the number of directories. ROFS frees you from such limitations.
With ROFS, you don't have to worry about file naming or disc structure
design any more.
Optimizes Performance of File
System
ROFS provides file access APIs designed for game consoles with
CD/DVD-ROM drive. Even when reading from a device with low access
speed such as CD/DVD-ROM drive, ROFS can optimize performance of file system
by performing quick file opens and fast data reads.
Best for file access on high-capacity ROM provided for built-in devices
As the built-in ROM capacity becomes large, data to be handled is getting large both in the number and the size.
Managing this large volume of data by the address within a ROM and by the size is reaching the limit.
To solve this problem, we suggest using ROFS: It allows you to access data within a ROM (on memory) as a file.
Access to Files on Virtual Disc
Image
ROFS handles a virtual disc image (ROFS image), which is created
from files used in a game program.
Game program accesses files on the virtual disc image that is
located on CD/DVD-ROM.
ROFS is an extension of the CD-ROM standard ISO9660. File processing can be performed using the same procedure as for CD-ROM. Functions such as file access by long file name and hierarchical directory structure are available.
(2) Handling Multiple ROFS Images
Multiple ROFS images can be handled simultaneously.
You can organize ROFS images according to your requirements,
such as by game scenes or by file types.
(3) Cooperation with CRI ADX
and CRI Sofdec
When ROFS cooperates with ADX or Sofdec, their file management
functions will be enhanced and extended.
ROFS is easily implemented in a game program that uses ADX or
Sofdec.
This work will be completed by adding a few lines of program
code.
(4) Data Protection
Packing files in a ROFS image prevents illegal data retrieval.
ROFS is stable and fully secure.
(5) Easy Data Management
ROFS prevents data management troubles such as using wrong files
or missing files.
ROFS proves its real worth especially when burning CD-Rs/DVD-Rs.
Large number of files can be reduced to some ROFS images, so discs will
be created quickly and accurately.
(6) ROFS Tools Support Image
Data Creation Work
We provide an image builder that creates an ROFS image, an image
editor that adds files to the existing image, and various ROFS tools are
provided.
