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.
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:
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.
Then it suddenly stopped working:

Unfortunately I won’t be able to use it with my Duo-RX and GT, and the SuperGrafx is too bulky and ugly to take it out for gaming. I ordered a cheap CoreGrafx from Yahoo! Japan Auctions which came with a Tennokoe 2 backup memory device attached to the expansion connector.

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.

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.
This is a GameCube that I acquired recently. It has a true HDMI output and blue controller ports.
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.
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):
