The Nintendo Gameboy Crib Sheet was put together to fill a very large need. All of the information concerning hardware registers, Z80 op-codes, memory organisation, DMA timings and lots of other details covering the Nintendo Gameboy and Nintendo Gameboy Colour are spread out across hundreds of e-mail messages, three books and many good, but usually incomplete documents found on the Internet.
I wanted a single reference that could jog my failing memory when I didn’t have time to go looking through a large text file for a vague, often inaccurate, piece of information.
I also didn’t want a 600 page "black book" about how to program the Nintendo Gameboy or Nintendo Gameboy Color that started off telling me how to open up a file in a text editor or what a hex editor was used for.
So the Nintendo Gameboy Cribsheet came about to fulfil that need. It contains as much information condensed in to as few pages as possible, no explanations, no clarifications, no instructions. Its a memory aid for when your brain needs a little jog. If you don’t understand something on the Nintendo Gameboy Cribsheet, look elsewhere, learn what it does, and then use this reference to remind you of the exact register or Z80 op-code. This is information for the hardcore who already knew everything there was to know about the machine and just needed to be reminded every now and again.
When I was thinking about an information reference, I wanted it to be really handy. The Nintendo Gameboy Cribsheet had to fill that requirement too.
I wanted it to reside on the desk next to the computer, ready to do it’s job.
When I needed it. Not when it was convenient for me to take a break and turn away from what I was working on to thumb through a reference book.
I judge the usefulness of a computer book by the number of coffee or Coca-Cola stains it has on it. Beverages by the computer always end up on whatever you happen to be reading. The Nintendo Gameboy Cribsheet had to be that kind of information reference. I’ve printed it out over a dozen times since it first began — not including testing where I was judging how small I could get the font before it became painful to read — because the pages are used so often they keep wearing out.
The Nintendo Gameboy Cribsheet consists of several pages of densely packed details. Almost everything you need to know about the Nintendo Gameboy and Nintendo Gameboy Color is on there.
The Nintendo Gameboy Cribsheet is designed specifically for printing on high quality laser or inkjet printers. It was never designed to be viewed on-screen. The higher the quality your printer, the better the results.
To obtain the best results from printing, make sure you use the best quality paper you can obtain that has minimum bleeding. "High Gloss" is a good choice if you are printing on an inkjet but you must be sure to remove the sheet from the printer the moment it has finished printing and allow it to dry for several minutes to prevent smudging.
The Nintendo Gameboy Cribsheet is only available in Adobe PDF format and most likely never will be converted to HTML, so don’t ask.
