If anyone remembers the old gameboy color one, I made a PCE version. So far only 1 page, but more to come. http://alexandria66.2mhost.com/~pcengine//pce_cribsheet/Otaku_no_PCE_cribsheet.png <- Here. Link about it can be found here -> http://pcedev.blockos.org/viewtopic.php?f=5&t=60&p=282#p282
Excellent document. Takes the standard information and lays it out in an extremely user-friendly visually accessible way. Since I don't know much about the PCE my only comment would be that it may be useful to include a small legend somewhere to explain the format of the opcode descriptions as well perhaps as some small notes on the general uses of the special registers.
I have more pages in the works. The 2nd pages gives cycle times, byte sizes, hex values for opcodes, and small descriptions of each base instruction. There's definitely more stuff to come BTW, these are meant to be used in printable form.
Yea, I assumed as much (for printable that is). I've used a similar crib sheet when working with SSE3 and x64 extensions for the first time (as well as less assmble-y things like libc functions and Cisco IOS commands).
The 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 & 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.
