This is the only commercially available GameBoy programmable cartridge that I know of. It contains 4 MegaBits of storage capacity and has software to store up to 4 different programs in this storage space.
I unit I purchased was made by China Coach Limited. When it originally arrived, it came with out a power supply and software. There were two pieces. A base unit that connects to a PC parallel port, and the programmable cartridge that actually is used with the GameBoy. There was also a message that they were out of software diskettes and they would email me the software.
When I finally received the software several hours later, the first thing I noticed was that the software said, 'Printer Port Error!' I wasn't sure if this was because I had a 100MHz Pentium or not. I tried the unit on every x86 Intel chip about ever made so I was further confused. On a brighter note, I could tell by looking at the software that a tremendous amount of time and effort was put into it so I was pretty darn sure that this was not a 'bogus' product, but that something simple was probably the source of my problems.
I was talking to someone that told me that early versions of the software are very timing sensitive and that he had a later version of one of the pieces of software if I wanted it. I immediately requested this and he sent it pronto. This seems to have cured the problem of reading the Smart Card so I feel much better already. Please note that when reading 'snapshots' from your computer that they MUST be in the form of 'GB*.GB' (For example 'gbtetris.gb'.) You will get a 'File Format error!' if you don't. I now have what I believe to be the latest version that I have modified to only display files in the format 'GB*.GB' since that is the only format the software recognizes.
