Neo Geo MV1FZS 5V and Stereo Mod

When I finally fixed my consolized MV1FZS last month and was able to play some games again, I notized that it outputs mono sound only. It is now time to make some some additional modifications to it.

5V Mod

MVS boards need both 5V and 12V voltages, and 12V is used for the audio amp only. As I’m going to add a new stereo audio circuit, there is no need for the 12V feed anymore. This consolized MVS draws the 12V from the now obsolete XL6009E1 DC-DC converter:

Neo Geo MV1FZS Battery and Backup RAM Error Fix

After having a great time with my MV2FS I was looking for something more compact that I could use in the living room. I came across a pre-consolized MV1FZS and played the entire Neo Geo library with it.

Neo Geo MV2FS at Home

Neo Geo games and hardware have been a part of my life for many years. As I was looking at store displays during the early 90s, I was amazed at how huge these game carts were in comparison with other consoles, such as the Nintendo GameBoy.

In the late 90s, the emulators NeoRAGE and NeoRAGEx introduced me to the world of Neo Geo and arcade emulation. At that time, MAME didn’t yet have the capacity to emulate those games properly and at a decent speed. Later on, when MAME finally became a useable Neo Geo emulator, it became quite easy to add new released games and dumps to the source code, and play them as well.

FM TOWNS II Fresh・E Battery Replacement

When my FM TOWNS II Fresh・E suddenly refused to boot from HDD and Towns OS (from CD) didn’t show the HDD anymore, my first thoughts were that the HDD has finally given up. It sounded like an airplane engine lately (and still does). Then I noticed that date/time settings were lost too, so it was probably related to the BIOS battery. To access or replace the battery (3V CR2450) the whole unit needs to be disassembled.

Atari Jaguar Power/Sound Fix and Rotary Controller

The other day I prepared my Atari Jaguar to build a rotary controller for Tempest 2000. I hadn’t used it in a while and accidently picked the wrong power supply – smoke was rising immediately from the console.

The culprit was easily found, chip U38 (MC34163DW):

Philips CDI 220 Mini MMC 60Hz Modification and TimeKeeper Replacement

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).

NEC PC-FX Laser Pickup HOP-E1

I’ve been struggling with a weak PC-FX laser for quite some time. What kept me from changing the laser or pickup unit was that having to take apart (and put it together later) the PC-FX is something you wouldn’t wish your worst enemy. However, getting close to the drive unit is surprisingly easy, just follow this guide.

First you need a replacement laser. I chose the complete pickup unit (Hitachi HOP-E1), it’s available for about 15€.
