So, it seems that cdi-emu does have better preliminary DVC support than has been commonly reported / realised, it is just that you have to have a very specific DVC bios. Most bioses that I have seen available are the VMPEG bios, but according to the emulator author, currently only the GMPEG bios is reasonably functional to run things like 7th guest etc. If you use the VMPEG bios it will crash at the first screen.

As quoted:

>What I call "proof of concept" DVC support has been in CD-i Emulator since 2010 or so. It already works well enough to run The 7th Guest and a number of other titles, but only for a specific version of the DVC cartridge (the so-called "Gate Array" version, GMPEG for short). Getting it to run on the other versions (VMPEG and IMPEG) is just a matter of bugfixing, the basic emulation for those versions is there already as they are architecturally very similar. But before that is going to happen I want to fix the issues with the current MPEG emulation which are mostly a question of emulation architecture (exact issues are technical and I won't go into them right now).

See https://www.theworldofcdi.com/community/emulators/announcing-cd-i-emulator-version-0-5-3-beta6-for-windows/

And also https://www.cdiemu.org/cditypes/

Unfortunately I have not been able to track down such a GMPEG DVC bios in order to test this, but it is at least something as cdi-emu seems to be considered the most robust of the cd-i emulators from what I have seen.

If anyone has such a bios dump and manages to test things out, it would be interesting to hear from you.

Very good improvements in compatibility, more games are working and better than before.

Any assistance is greatly appreciated, including information on game compatibility, there are too many to test by myself. Please also report any minor defects you encounter.

Laser Lords was one of the CD-i games I always wanted to replay, but I could never get it running well on my Steam Deck. So I tried something different.

I'm not a coder, so I built this with Claude Code (AI). Instead of emulating the whole CD-i, it runs the game's original code and rewrites the CD-i system around it so it runs as a normal app. No CD-i BIOS needed. To get the details right, we compared everything against MAME running the real CD-i: intro timing, walking speed, screen layout, sound.

Honestly, I was hesitant to share this. I made it for myself, not as a polished project. But then again, why not? I hope other people can enjoy this weirdly wonderful piece of forgotten history as much as I do.

Some caveats:

• This is a preview and I haven't tested it extensively, so it may not be perfect.
• No game files are included. You need your own disc image (.chd or .cue/.bin). Please don't ask me for it, they are not that hard to find.
• Unofficial fan project, not affiliated with Philips or the rights holders.

Hello, for those interested, my new second FMV Game: Dead End is now available.https://condorgames.github.io/

Anyone selling a cdi controller? Or even an adapter for different controllers? Mine has been destroyed by the bloody dog! 🤦‍♂️

Hi everyone! I just released OpenCDi v0.1.6, an open-source Philips CD-i emulator written in Rust.

This update represents a major leap forward in **game compatibility** (especially for Digital Video Cartridge titles), introduces **full Video CD (White Book) support**, and completely overhauls **gamepad/cursor responsiveness**.

Highlights in v0.1.6:

**1. Major Game Compatibility & DVC Enhancements**

* ***The 7th Guest* Progression Fix:** Overcame the critical post-ghost cutscene lockup (`avm_play: Still busy from last play $8000`). Temporary audio drains now strictly assert hardware underflow (`FMA_IRQ_UNF`) rather than premature `EOI`, allowing disc streaming to reach the authentic second EOR marker and unlocking full hallway progression.

* **Automatic DVC Detection:** The Digital Video Cartridge is now fitted by default whenever `vmpega.rom` is present. This fixes "Cartridge not found" blocks on titles like *Kingdom: The Far Reaches*, *Mutant Rampage: BodySlam*, and *Ultra CD-i Soccer*.

* **Seamless Multi-Disc Hot-Swapping:** You can now swap discs on the fly without resetting system RAM or CPU state, making multi-disc games like *Creature Shock* (Disc 1 -> Disc 2) fully playable.

**2. Full Video CD (White Book) & Multi-Track Support**

* **Multi-File `.cue`/`.bin` Layouts:** Added complete support for complex multi-track disc images with separate audio/video tracks (tested with *Kilby Predicts*, *Gateway to the Mind*, and standard VCD releases).

* **CD-Bridge Support:** Implemented dynamic Subcode Q TOC packet generation for authentic CD-RTOS CD-Bridge format handling.

**3. Smooth Gamepad Navigation & Slave MCU Accuracy**

* **Goodbye Cursor Snapping:** Fixed the abrupt jumping across 8 pre-set screen coordinates in the dashboard. Input now runs at a smooth, continuous 2.5 px/frame powered by `f32` sub-pixel accumulators with zero drift on release.

* **Slave MCU (68HC05) Packet Staging:** Added queued staging for in-flight CH0 mouse/pad packets, proper 3-byte `C0` warp command decoding, and clean mouse/gamepad mutual exclusion.

Feedback, bug reports, and testing results are hugely appreciated!

This was one system that I didn't plan on purchasing. The rarity and expense of this console and games can be quite off putting. I found this at a little retro shop I frequent. Working Cd-I 450. I received Paint School 2 with it and he happened to have 1 other game, The Palm Springs Open. Looking to find a Hotel Mario and try out one of the most obscure Mario games! Maybe even a Zelda if the price was right. Just wondering if you all have any certain websites with games avaliable (besides ebay) that you use?

Mega Race for the Philips cd-i ported from the dos version. pure fmv cheese. enjoy!

Here is my first FMV game it runs on an emulator but without music its is only fully playable on an actual player https://condorgames.github.io/

As the title says is there someone in sweden qho repairs cdi players?

I recently bought a Philips CDI 450 that can't read discs. One thing I noticed is that the status shown in the menu is always stuck on "DISC." Supposedly, when the disc tray latch is open, the status should change to "OPEN," but it stays on "DISC" regardless of whether the latch is open or closed.

I checked the latch switch with a multimeter, and it seems to be working correctly. When the switch isn't pressed, it outputs 5V to pin 4 of IKAT. When pressed, the voltage drops to 0V. Does anyone know what could be causing this?

I really hope that IKAT chip is not malfunctioning, there's no replacement for that as far as i know.

Nobody is talking about it but I think it's pretty huge news.

As of a few days ago, the CD-i DVC (Digital Video Cartridge) was implemented in MAME. You'll have to wait for the next version of MAME (.290) to have it included, unless you're capable of compiling the source from github (which I did.)

I never owned a CD-i in the 90s, but I always read about it in the gaming mags back then, so I think it's awesome this is finally emulated and liberated. No longer are we stuck with that time-gated and pay-gated CDiemu!
I streamed a couple videos of it on youtube under "nirvgorilla" if you want to see it in action.

To me it's one of the most pretty games on CD-I but it's incredibly hard. A more fair difficulty option would be nice as the gameplay is basic, but fun. It shows how good platformers could be on CD-I.
