Game Link- 2000-10-16 - Adding a Game Link to a Super GameBoy - Posted by: Jeff Frohwein
- The idea came from a web page in Japanese, so the original credit goes to the authors of that page, Papa and Shaora, as they are the ones who figured out that it would work. You may want to check out their page for the pictures.

- Diode added. Diode is needed by some PC ports. Up until now this cable has only worked on some computers due to a design bug (Thanks go to Scott Kroeger for finding it. :) It *should* now work on most computers. Here's a schematic for connecting your GameBoy to an IBM-PC Parallel Port for exchanging data. NOTE: ONLY GB BASIC CURRENTLY MAKES USE OF THIS CABLE.

- 2000-10-16 - MadCatz GameBoy-to-PC Cable - Posted by: Jeff Frohwein
- Here's a schematic of the cable made by Mad Catz which appears to use a PIC chip as an interface. The circuitry all fits inside the clear purple DB25 connector housing and uses a DIP package that can easily be replaced with a machined socket. Check the Mad Catz page for suggested price & cable photo.
NOTE: The data format for using this interface and the code required to program the PIC chip ROM are unknown by myself.

GB/Cart- 2000-10-16 - 134a Power Down Chip - Posted by: Jeff Frohwein
- Here is the 8 pin 134a chip found in MBC5 carts that contain RAM + Battery. It protects cart RAM from false writes during power down. This document is in PDF format. It appears to be the same as the 26a chip found in MBC1 carts with RAM. Here is a simple view of what this chip does.

- 2000-03-01 - Super GameBoy Schematic - Posted by: Jeff Frohwein
- When I saw Super GameBoy's on sale at the local store, I though, "Do I need this?" The longer I though about this the more my curiosity of what might possibly be inside seemed to take over my whole thinking process. I reached the point of 'no return'. I had to buy it relieve my curiosity. What I discovered inside is basically that it seems that the Super GameBoy is a regular GameBoy minus some parts (i.e., LCD, keys, power supply). An extra chip is added to interface the GameBoy to the SNES to control key inputs and to capture video to display.

- 2000-03-12 - Jeff's GameBoy Robot - 'CyberWeasel' - Posted by: Jeff Frohwein
- Here's my GameBoy robot. Here's a bottom view. The mechanical kit I got from lynxmotion. For electronics I used a GameBoy Pocket, a game cartridge with SRAM (and the ROM removed), the GameBoy I/O Example, Robot Power/Servo Schematic and a 27C256 eprom running GB Basic. The eprom /CE is supplied from the GameBoy I/O Example. Even though I've already programmed it to move small objects around, basically this is just the starting point for more advanced electronics. Notice that there is still plenty of space underneath for future electronics expansion.
