Philips CD-i 660

Philips CDI660 Service Shell

For quite some time, I was puzzled why my CDI660 was stuck in a reset loop after I inserted the test/dummy plug into Input 1. I expected it to boot into the Service Shell, like most other CD-i players. My solution so far was to use a 490 system ROM in the 660 whenever I needed the Service Shell (the compatibility and also the error were discovered during this experiment). However, this wasn’t a very practical approach because I had to open up the player and dig out the system ROM from underneath the DVC every time.

When CD-i Emulator with -testplug option showed the same behaviour, CD-i Fan figured out what is causing this error: The Service Shell module sv is missing from the 660/670 system ROM.
In this article, I will show you a simple ROM patch to enable the Service Shell for the CDI660.

Modifications for Philips CD-i Players

This is an attempt to collect all known and available modifications for Philips CD-i players in a single article. Consider it a work in progress – I will add new information from time to time. Please give feedback if you find an error or want to add something to this article.

Due to the plethora of different models, versions and revisions of CD-i players that have been sold under the Philips / Magnavox or entirely different brands (OEM), it is virtually impossible to create one big list that contains every player. I chose a different approach with several lists to cover most of the hardware combinations: Available modifications, mainboards, video encoders and NVRAM.

Philips CDI660 Mono IV NVRAM and 60 Hz Modification

The CDI660/00 is one of the last professional CD-i players by Philips. The mainboard, Mono IV, is also used in various consumer players. So far, there are no tutorials for 60 Hz modification. When this topic came up in the community on The world of CD-i, I looked it up in the CDI220/80 service manual (also Mono IV, with plenty of remarks for other player models) and attempted the modification myself. It has been on my to-do list for quite some years now.
First, we need full access to mainboard. Remove the marked screw of the DVC plastic holder.

TAB Quizard on Philips CD-i

Quizard was a series of quiz games published by TAB-Austria in the ’90s. What makes it special is the fact that it is one of the very few arcade games based on Philips CD-i hardware. The protection of Quizard 1.x and 2.x has been figured out quite a while ago and since then it is emulated in MAME. Quizard 3.x and 4.x, however, refused to run – until now. A first step was done when Team Europe dumped a protection MCU a couple of years ago. Very soon, they will release an MCU board that will turn almost every CD-i player into a Quizard arcade machine. I received a sample last week and just finished assembling and testing it.
