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

2018 will be a great year for the PC Engine. Terraonion, the maker of the NEOSD cartridge, has announced the Super SD System 3 add-on.
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.

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.
Changing settings in the BIOS of a japanese computer can be dangerous if you don’t have any knowledge of the japanese language or don’t what you’re doing. I don’t have that much knowledge of the language either and tried to translate the BIOS.
This is how I did it: I connected my PC-9821Xe/U7W with a sync combiner to the Framemeister and grabbed a video of the selection of each and every BIOS menu item. Then I converted the frames of the video to image files. The images were then cropped and converted into grayscale negatives to be processed by an OCR engine. Most of the output was gibberish and every single line of text needed manual processing. The japanese text was then fed into the Bing and Google translators and some common sense added to the output.

The 7th Guest is a great game for Philips CD-i. Unfortunately, there is an annoying bug that crashes the game when trying to solve the cake puzzle:

Last year I replaced the broken GD-ROM of my Sega Dreamcast with a GDEMU. While it works great and does everything as it is supposed to do, there is a large open space where SD cards tend to get lost:
This modification adds switchless NESRGB and IGR (in-game routines / in-game reset) to a Nintendo AV Famicom.
A first look at the opened AV Famicom and the NESRGB kit. There is still a lot to be assembled. The installation guide for the AV Famicom can be found here.
