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:

Pippin Atmark ADB Adapter Dongles

Initially, I was planning to replace the P-ADB connector of my AppleJack controller with an ADB plug (Mini-DIN-4). The remaining P-ADB plug attached to a Mini-DIN-4 socket would then become an ADB adapter dongle.
But why would I destroy the cable of my only controller? According to the documentation, which can be found here and here (in a very low resolution, unfortunately), a “Hosiden HGC0492-01-010 or equivalent” connector is needed. And that connector is impossible to find.

To get started, I created a new schematic based on the available documentation:

Terraonion MegaSD Cartridge

This has just arrived yesterday: The Terraonion MegaSD Cartridge. The makers are known for quality products like the NeoSD and the Super SD System 3. Their recent move of the office from Spain to Andorra has stirred some controversy and caused over-the-top reactions from some buyers. I didn’t experience any trouble and my cartridge arrived safely within a few days. This is what I got:

Sega Pico Pen Repair

When I bought a second-hand Sega Pico in 2015, I immediatly noticed that something must be wrong with it. I didn’t expect a lot of interactivity or gameplay, but at least it should let me draw something. It turned out that the pen was registering the position/movement and also made a clicking noise when pressed down, but nothing else happened. The error was quickly found and repaired (broken micro switch), but the photos have been waiting on my hard drive ever since. A short repair instruction was posted on the ASSEMblergames board in the following year, so I didn’t see the need to rush out an article. Well, here we go:

The label of the pen is missing and it seems that somebody tried to open it up before me:

Sega Dreamcast Karaoke

The Dreamcast Karaoke is probably the most useless Sega add-on. It serves no other purpose than to accompany the Sega Kara software, which is useless as well.

Back in the days you were able to download and sing thousands of songs, then in 2006 the servers were shut down for good.
Without the servers there are no songs – you can still connect microphones to the Dreamcast and listen to your voice with Sega Kara, change the volume and add effects, but that’s about it.

3RADD – The 3-D Sound For Video Games And PCs

An unusual SegaSaturn accessory: The 3RADD – A sound enhancer with SRS psychoacoustic technology. Read a review on this japanese blog. Here is a scan of the manual.

The effect with audio sources is quite nice, it boosts the sound and positions it around your head. The technology is used in all kinds of devices and software, e.g. the Windows Media Player (SRS WOW).
