,/* Opcodes */
All CB-prefixed opcodes and half of the standard opcodes (from &40 to &BF) follow a strict uniform layout. The sole exception is the HALT instruction (opcode &76), which replaces the expected LD (HL),(HL) instruction.
The rest of the opcode table is also neatly organised but in an a horizontal way instead of vertical.
Any instruction in bold is undocumented by Zilog.
