+
+ System dependencies: UINT16 must be 16 bit unsigned int
+ UINT8 must be 8 bit unsigned int
+ UINT32 must be more than 16 bits
+ arrays up to 65536 bytes must be supported
+ machine must be twos complement
+
+ History:
+991022 HJB:
+ Tried to improve speed: Using bit7 of cycles1 as flag for multi
+ byte opcodes is gone, those opcodes now instead go through opcode2().
+ Inlined fetch_effective_address() into that function as well.
+ Got rid of the slow/fast flags for stack (S and U) memory accesses.
+ Minor changes to use 32 bit values as arguments to memory functions
+ and added defines for that purpose (e.g. X = 16bit XD = 32bit).
