Simple Media System is a community project with a long history. Every feature in this build stands on someone else's code and someone else's ideas — a media engine written two decades ago, a homebrew community that kept it alive and modern, and the storage-integration groundwork this fork was able to build on. This page names the people and projects it is grateful to, and cites its sources.

CREDITS

Built on twenty years of shared work

SMS began as one developer's quest to play good-looking video on an unmodified PlayStation 2, and became a community effort spanning USB, HDD, network, a GUI, a skin engine and a long list of formats. This fork adds storage breadth — MX4SIO playback, exFAT, i.LINK, MMCE, SMB and UDPFS — plus DualShock 3/4 support. None of it would exist in isolation.

The foundation

The heart of SMS is Eugene Plotnikov's original media player and the years of ps2homebrew community work that modernised it. This fork's contribution is a focused one — making MX4SIO microSD playback work reliably and adding several more storage devices — but it rests entirely on that shared foundation.

Eugene Plotnikov: The original author of Simple Media System (2001–2005). He built the PS2-optimised, FFmpeg-derived video/audio player that uses the console's IPU for colour conversion, and devised CDDAFS — the technique for storing data on an audio CD so an unmodified PS2 accepts a burned disc. Everything SMS is began here.
The ps2homebrew community: The maintainers and contributors who adopted and modernised SMS over many years — adding USB, internal-HDD, network (SMB) and playlist support, a GUI file browser, the .smi skin engine, and support for many more container and codec formats. The PS2SDK, the IOP module ecosystem, and the toolchain this fork builds with all come from that same open, community-maintained work.
KrahJohlito: Provided the BDM + MX4SIO integration foundation this fork builds on: loading the block-device (BDM) module stack, the memory-card/pad rework that a shared SIO2 bus requires, and the device-menu wiring that lets MX4SIO appear as a first-class device. This groundwork is what made the playback fix possible to land.
El_isra, Ripto & Berion: Additional work and testing around the MX4SIO effort. Real-hardware testing and feedback are what turn a build that merely compiles into one that actually plays — and this fork's MX4SIO support was shaped by that hands-on QA.
bbsan2k: Author of the MMCE (Memory Card Mass Storage) protocol — the protocol behind loading files from an SD2PSX or MemCard PRO2 through the PS2's memory-card slot. This fork's mmce0: / mmce1: device support builds directly on that work. See MMCE.
rickgaiser, Maximus32 & the neutrino contributors: The UDPFS / UDPRDMA, ministack and SMAP foundation vendored from neutrino. The working load sequence was cross-checked against wLaunchELF-R3Z. SMS carries documented local integration changes while preserving upstream attribution.
The Open PS2 Loader contributors: The DS3/DS4 USB and Bluetooth driver/client foundation vendored from Open PS2 Loader, adapted here for SMS's controller path and in-app Bluetooth pairing.
The FFmpeg project: SMS's video and audio decoders trace their heritage to FFmpeg. Plotnikov's original player was a heavily PS2-optimised port of parts of FFmpeg, and the decoder lineage — for AVI/MP4 MPEG-4, MPEG program streams, MP3, AAC, AC3, FLAC, OGG and more — reaches back to that project's contributors.
This fork: The storage-focused work documented on this site: the MX4SIO microSD playback fix (the headline feature), exFAT internal HDD over ATA alongside classic APA, i.LINK storage, MMCE devices, the UDPFS network drive, fully on-screen network & SMB setup, DualShock 3/4 integration, config that saves to the boot device, MP4 support, a refreshed theme and device icons, and this documentation.

What this fork contributes

To be precise about which parts are new here versus inherited: this fork's own work is the storage-breadth layer and the playback fix that headlines it. At a user level, that means:

MX4SIO microSD playback — video and audio now play smoothly from a microSD in an MX4SIO adapter, with a hardened driver that keeps playback reliable under a media player's load. See MX4SIO.
exFAT internal HDD over ATA — modern exFAT drives read alongside the classic APA/PFS SMS_Media partition. See Internal HDD.
i.LINK (IEEE 1394) storage — a FireWire drive as a media source. See i.LINK.
MMCE devices — browsing media from an SD2PSX or MemCard PRO2 in the memory-card slot. See MMCE.
UDPFS network drive — a folder-served network filesystem at udpfs:, distinct from UDPBD. See Network Setup.
On-screen network & SMB setup — configure your IP and connect to a share entirely from the pad, no hand-edited config files. See Network Setup.
DualShock 3 / 4 support — wired USB and Bluetooth input, with controller pairing inside SMS.
MPEG-4 Part 2 MP4 playback — mp4v video with AAC audio, covered by the hardware test pack.
Settings that save anywhere — configuration persists to the memory card or to the device SMS booted from. See Settings.
A refreshed theme — new desktop artwork and device icons, on the existing skin engine. See Themes & Skins.

Why is this a fork, and where does the canonical SMS live?

The community-maintained SMS project lives with the ps2homebrew organisation, and its documentation is at ps2homebrew.github.io/SMS. This documentation covers a downstream fork focused on storage breadth — it makes MX4SIO microSD playback work and adds exFAT/ATA HDD, i.LINK, MMCE and UDPFS devices, moves network and SMB setup fully on-screen, adds DualShock 3/4 support, and refreshes the look. It is a labour of love built on the work of everyone named above; the long-term home of SMS remains the community project.
