I want to install one of these on my slim 90004 but Wherever i look theres like no evidence of a diagram

So, I recently bought my first PS2 (a slim 79000) and it came with a "OPL kit" - memory card and a SanDisk microSD, which was read by a sort of MX4SIO thing already plugged.

However, I realized that my games (especially Bully) were running way worse than I would expect, and decided to take a closer look at my "memory card to microSD" thing.

I then realized that it was basically a usual memory card - from 2014 - modded (probably by its past owner) to be a microSD reader.

My question is: if I replace it with a original MX4SIO (which seems to be the most reliable option for sd cards), will it most likely solve my performance issues or it can be another thing?

I've been working on an experimental Jellyfin client for the PlayStation 2 called "Jam N' Jelly"! I finally have enough of it working that I thought it was worth sharing! My dad recently started messing around with Jellyfin, and I thought it would be interesting if I could get Jellyfin running on PS2. The repository is currently private, but as I get more features implemented I plan on eventually making the project open-source on GitHub. At the moment, it only runs under PCSX2 because it relies on the "host:" filesystem tags but I have been working on streaming video data over TCP. It's been incredibly difficult to configure PCSX2 for TCP networking on my VM, so I'm probably going to use ps2client for future testing on hardware.

The project currently has a Netflix-style media browser with posters, banners, detail pages, search, and an on-screen keyboard, along with a custom video playback pipeline that runs entirely in software. It uses a custom LVID video codec designed specifically around the PS2’s hardware limitations, including support for playing video files while they’re still being encoded. The player uses double-buffered software framebuffers, dirty-tile rendering to reduce GS/VRAM transfers, and IMA ADPCM audio playback through the IOP. There’s also a custom font and texture asset pipeline.

How it Works

The PS2 does not have any hardware H.264/H.265 decoder, and trying to decode modern codecs directly on the hardware was pretty much a dead-end. So instead of trying to port something older like MPEG2, I decided to write my own codec that was built around the quirks of the PS2.

.LVID uses:

- YCbCr 4:2:0

- Quadtree tiling ~ Areas that are largely static use larger rectangles to use less file-space, whereas tiles that move or have new color data often use smaller rectangles to adjust the colors easier and make details more visible

- Motion prediction

- LZ4 Compression

- YCbCr to RGB via CLUTs

- AdPCM Audio

I'm also currently working on taking advantage of VU0 in COP2 mode to help with the decompression of frame data (hopefully this will take some load off of the EE).

Most of the expensive work happens on the PC/server side during the encoding process. The PS2 is intentionally dead simple so it can be as fast as possible. Basically, it just: decompresses, apply motion data, reconstruct the frame data, push changed tiles to GS. One of the biggest wins with the LVID file is the --streaming flag. With this flag enabled, the encoder will write to the LVID file as the PS2 is actively playing it. The PS2 periodically checks the frame table for newly encoded frames and continue playback as new frames come available. In the video at 1:45, you can see this because pressing the "skip to end" button only jumps to 03:07 / 10:34 in the video. All of this is able to fit into the 32 MB of system memory, alongside the application, textures, framebuffers, audio buffers, etc.

>Note: Audio data is converted at the same time as frame data, and fed directly to the SPU

Release Date

The project is still very experimental. The core media pipeline and GUI work at a basic level, but it currently lacks the visual polish that I want it to be at. Moreover, I have only tested using a python http server, and have not interfaced with an actual jellyfin server yet. Right now I am primarily working out how the PS2 can actually handle the media side of the project before building out the rest of the client. I do eventually plan on supporting music playback in the client as well.

I want to finish the project before December 2026, but I will see how realistic that deadline is once I start University. If anyone has any feedback or ideas for the project, feel free to comment! I am fully open to new ideas and additions!

Current Ideas

- LRU Cache for "Recently Watched" movies

- Support a YT-Music style audio playback engine

- Jellyfin CSS styling converter

GUI

If you want to see what plans I have for the GUI, take a look at the Figma project!

A lot of the updated GUI theming is heavily based on the PSL1GHT JellyFin client on GitHub.

Been rocking with my dream console completely stock for 2 years now, only playing NTSC-J games, had no idea about OPL.

Since discovering this community I’ve fully invested in maximizing this console and I’m currently working on an OPL fork of my own (more to come on that).

OEM network adapter off eBay for $25, the Sakura pink console and controller, 3D printed the vertical stand (did my best to color match with some hand painting, still need to paint the PS2 logo).

What do we think of the setup? Ripping 30 more of my disks to ISO this week, will share the library when it’s complete.

Thanks for being an awesome community and keeping this console alive.

Does anyone know a faster efficient way of mass deleting games on the modded ps2, going through them individually to delete takes forever and is time consuming, i have about 300 games to get rid of that i will not be playing, do i need to plug the hard drive into my computer or is there a easier way to doing this? Thanks.

So as tutorial follows: burn freedvdboot into dvd-r, install freemcboot into fat32 usb, then insert burned dvd-r, usb, and a memory card into ps2 and wait for that custom menu to load.

But the problem is my ps2 slim refuses to read the dvd-r with the message saying the disc could not be read, but the console does read official ps2 game discs, what am I missing? My dvd player is 3.11E so it should read 'all ps2 slim" iso file but it doesn't. I followed a bunch of tutorials all of them have the same steps, what do I do?
