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.

Philips CDI490 RGB SCART Modification

It has been on my table for a while to figure out a working Philips CDI490 RGB SCART modification. The topic caught my interest when it came up in the community on The world of CD-i last year. Back then, I thought it would be quite easy because the small 470 and 490 CD-i players share a certain mainboard (Mono IV) with their big brothers 660/00, 220/80 and 210/60. There are only some components missing that could be figured out by looking at the service manuals.

However, I couldn’t try it out back then because I didn’t have a working 470 or 490. I focused on repairing my 470 first and then adding a PAL/NTSC switch. Eventually, I bought the needed components and two broken 490s to experiment with.
