I am revising opcode tables (have not yet finished ;-)
and have found many errors, at least in the 0xED
prefixed opcodes table. As an example, according to
Zilog's Z-80 manual, LD (nn),BC opcode is ED 03 nn nn,
and not ED 43 nn nn (I have also found this concrete
error in other non-oficial opcode tables/manuals/etc...).
I can send you correct tables once finished, if this
project is still "alive".

    I'll check it out. IIRC, some instructions have more than one
    opcode. But I might be wrong :)

    I don't know which manual the original submitter was
    reading, but http://z80.info/zip/z80cpu_um.pdf (correctly)
    lists LD (nn),BC as ED 43 on page 55 (page 73 in the pdf).
