# romdirfs - ROMDIR filesystem in userspace

romdirfs is a userspace filesystem for Linux and macOS that allows you to
access the IOP modules contained in PS2 IOPRP images and BIOS dumps. The tool
can mount the so-called ROMDIR "filesystem" in those PS2 files to a directory,
thereby mapping the included IOP modules to actual (read-only) files.

I mainly developed romdirfs because I was interested in the technology behind
[FUSE] and wanted to implement a simple filesystem on my own. (With FUSE, you
can easily export a virtual filesystem to the Linux kernel without root
privileges.)

More recently, I created a [Rust spike] for the same reason.

## Installation

romdirfs requires a working FUSE implementation. Under Ubuntu/Debian, you can
install the package `libfuse-dev` (version 2.6 or higher). Get [FUSE for macOS]
if you are on macOS.

To build and install romdirfs, simply run:

$ make
    $ make install

CMake is supported too:

$ mkdir build
    $ cd build/
    $ cmake ..
    $ make
    $ make install

## Usage

usage: romdirfs <file> <mountpoint> [options]
    <file> must be a PS2 IOPRP image or BIOS dump

ROMDIRFS options:
        -V, --version          print version
        -h, --help             print help
        -D, -o romdirfs_debug  print some debugging information

You can get the complete option list with `--help`.

To unmount the filesystem on Linux:

$ fusermount -u <mountpoint>

To unmount the filesystem on macOS:

$ umount <mountpoint>

## Examples

Mounting a PS2 IOPRP image:

$ mkdir /tmp/romdir
    $ romdirfs ioprp15.img /tmp/romdir/

$ mount | grep romdirfs
    romdirfs on /tmp/romdir type fuse.romdirfs (rw,nosuid,nodev,user=misfire)

$ ls -l /tmp/romdir/
