Repair a Xbox 360 Controller

If you drop a Xbox 360 controller don’t let it land on it’s bumper buttons. The micro-switches break easily in the inside. They might still work but need more pressure to be triggered. This problem plagues old Sega Saturn gamepads too.

To open Xbox 360 controllers you need a special Torx security screwdriver with a hole in the tip, size T8H. If you don’t have this rather unusual screwdriver you can break the tiny pins in the screws and unscrew them with a regular T8 or T9 Torx screwdriver. Seven screws need to be removed (yellow circles). One of them is hidden behind the white sticker with the barcode and not behind the black sticker where I looked for it first (red circle).

Datach Joint ROM System

The Bandai Datach Joint ROM System is an add-on for the Nintendo Famicom. It plugs right into the cartridge slot and comes with its own small cartridges. The games are enhanced with barcode cards, similar to the Mattel HyperScan.
The retail package with one include game, Dragon Ball Z: Gekitō Tenkaichi Budokai, is rather easy and cheap to obtain.

Additional games are very rare and even rarer and pricier when the corresponding barcode cards are included. I’ve seen some bootlegs of those games on regular Famicom carts but never tried them so far.

Card Games – Mattel HyperScan

In 2006 the Mattel HyperScan was a short lived console with an interesting concept: Enhance a classic videogame with collectible RFID cards. A concept that was picked up in a similar form by the Skylanders games and maybe someday will be used in Nintendo’s new Wii U console.

Playing the games (and scanning cards) can be described as interesting but not as fun. The games seem unfinished and buggy. And then there are the long loading times, a problem already the NeoGeo CD suffered from back in the days.
There were even some first steps with homebrew programs here and here.

Disassembling the Sharp Turbo Twin Famicom

In the 80s Sharp made some interesting devices powered by the Nintendo Famicom/NES technology. The less known devices are the Famicom Titler, a video subtitler, and the C1 NES TV/Sharp Nintendo Television, a television set. More common is the Twin Famicom, a console that plays Famicom cartridges and Famicom Disk System Disk Cards (and, with a 72-to-60-pin adaptor, NES cartridges too). This is the black Turbo version AN-505-BK:
