Capcom CPS2 Digital AV Interface Firmware v0.91

Last weekend, marqs released firmware v0.91 for the CPS2 Digital AV Interface. The new firmware finally has an OSD implemented and brings back the scanlines. Further features include TX mode, quad stereo output and two additional VESA resolutions (1280×1024 and 1600×1200). You can find all functions and some explanations among the OSD menu structure and the sample pictures below.

Updating the firmware takes less than a minute and is basically the same procedure as updating an OSSC via JTAG. I’ve explained the procedure in this article.

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.

Pippin Atmark Controller for Macintosh

I’ve recently acquired the Bandi Pippin Atmark Controller for Macintosh (PA-82004) and took it apart today to see what’s inside. I didn’t expect a lot of surprises because this is the Apple Desktop Bus (ADB) version of the Pippin Atmark AppleJack Controller (P-ADB).

The small box contains the controller, a driver/software disk and a leaflet with instructions. You will find some more information about the software below.

Sega Saturn (PAL VA3) Modifications

This is a follow-up to the modifications I did to a NTSC VA15 Saturn. In this article, I will implement the following Sega Saturn (PAL VA3) modifications: Region-free BIOS, FRAM, and a 50/60 Hz switch (SW4).

After finishing the last article, I took three broken PAL Saturns that I had lying around apart to see what I could repair and modify next: A Model 1 with VA1 mainboard, a Model 1 with VA3 (aka “PAL VA SD”) mainboard and an almost identical Model 2 (VA5, also “PAL VA SD”). I had only one working Type-B power supply, so I had to make a choice. I went with the VA3 Model 1 because the mainboard was in the best condition and only needed a working disc drive and power cable, reset button stick, power suppy and some cleaning. This is how is looked before:

SD2SNES Pro SuperCIC Compatibility

Today, I wanted to try out the pre-release sgb06 firmware. It is a fork of the original SD2SNES (aka FXPAK) firmware and implements support for the Nintendo Super Game Boy 2. After I had set everything up, I was wondering why the SuperCIC was disabled. I remembered then that I had bought a SD2SNES Pro last year, but never used it because of this:

Right now, it seems to have a bug when used in combination with a SuperCIC. As soon as the SuperCIC is enabled in the configuration, there is no picture and sync is lost (also, weird readings on the OSSC display). Upon switching the frequency, the LED of the console turns red and is stuck in that status. According to this thread, a firmware update is needed for one of the SuperCIC chips. I’m looking forward to see if this can be resolved through a SD2SNES firmware update. Otherwise, I’ll have to desolder and flash one of the SuperCIC chips.

Sega Saturn Modifications

This article is about implementing the following Sega Saturn modifications: Region-free BIOS, FRAM, and switchless 50/60 Hz.

But first, we’ll need to go back in time a decade or so. Back then, I was modifying my “This is COOL” skeleton SegaSaturn (HST-0021/HST-3220) like crazy, stuffing everything inside that I could find:

Philips CDI350 Repair Part 3

It’s been a while since I opened my first Philips CDI350 portable CD-i player and published a repair guide with capacitor list. I have already received some positive feedback that this was helpful for others fixing their players. However, part 2 of the article ended with a big question mark because some topics remained unsolved. Let’s have a look at the status of these topics and see if I can resolve them today in Philips CDI350 Repair Part 3.

1. S-Video output is not working

This turned out to be my fault. After carefully following the traces to and from the video encoder and comparing every component with the service manual, I noticed that I had soldered two electrolytic capacitors with the wrong polarity: C938 and C991. I can only assume that this happened because I used the + marks as indicators and not the white dots. Just look at the vast amount of plusses:

Pippin Atmark Floppy Unit PA-82002

The Bandai Pippin Atmark Floppy Unit PA-82002 is an expansion dock for the Pippin consoles that made it past the prototype stage. It was released on the Japanese market together with the Pippin Atmark in 1996. It is still incredible rare and it took me while to get a hold of one of these units. The functionality is the same that the replica floppy adapter provides and the main reason why I bought it is really the casing. The floppy adapter setup was too unpractical and fragile and I was looking for something sturdier that could stay attached to the console at all times.

This article is mainly about photos and taking it apart. There will be a small section with explanations at the end.

Back Up and Restore NVRAM Data With CD-interlink

This is the second part of the follow-up to my article from 2013 and explains in detail how to back up and restore NVRAM data with CD-interlink. The other option, CD-i Link, and how to connect a Philips CD-i player to a modern Windows PC is covered in the first part. Make sure to follow the guide to set up the connection and the terminal program Tera Term.

CD-interlink (alternate spelling: CD-i’nterlink, CD-Interlink and CD-InterLink) is a program developed by Novaré International (and human interaction inc.) in 1994. It is dubbed The Complete CD-i File Manager and has some useful functions to view and manipulate single/multiple files in the NVRAM. Some functions require the connection to a terminal. At first sight, it seems to be easier to use for beginners because it has a graphical user interface that can be operated with a CD-i controller. Don’t get fooled by this though, because file transfers are actually more complicated to set up than with cdilink.
