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.Continue reading TAB Quizard on Philips CD-i
Recently I found a CDI 220/00 with Mini MMC mainboard. It’s a heavy and bulky unit that contains lot of PCBs, wires, screws and metal parts. It’s one of the first consumer CD-i players. Later models have all components on one single mainboard (Mono).
Chapter 5 of the Philips CDI 220 service manual (the manual that helped finding the right spots for the 60 Hz modification) deals with the built-in service software:
5 SERVICE SOFTWARE
In the set there are 3 different testsoftware available:
1. FTD-display/keyboard test
2. Low Level test
3. Service Shell
I’m going to cite the instructions for 1. and 3. and add pictures or comments if needed (I’m not going to cover 2. as it requires an extra service pcb and/or terminal).
Note: The service manual is valid for the Philips CD-i players CDI 220/20 220/25 220/39 (PAL) and CDI 220/31 220/37 (NTSC). On other players/models the test instructions should be similar if not the same. Continue reading Philips CDI 220 Service Software / Self-Test
When looking for a modification to improve the video size/quality of DVC games on my PAL CD-i player, I’ve found that only two tutorials are covering that kind of modification (here / here and here). The modification enables a PAL player to display full screen video without the black bars on top and bottom. NTSC players benefit from this modification too, as there are PAL exclusive software titles that already have full screen video (e.g. De Zaak van Sam) – without the modification, parts of the screen are cut off.
Unfortunately, the mainboard of my CD-i 220 differs from those used in the tutorials, so I had to get a service manual to figure it out myself. The service manual I found is valid for the Philips CD-i players CDI 220/20 220/25 220/39 (PAL) and CDI 220/31 220/37 (NTSC). It says there is an unimplemented connector 1201 in square C6 of the mainboard:
