/*** konami: Portable Konami cpu emulator ****************************************** Copyright Nicola Salmoria and the MAME Team Based on M6809 cpu core copyright John Butler References: 6809 Simulator V09, By L.C. Benschop, Eidnhoven The Netherlands. m6809: Portable 6809 emulator, DS (6809 code in MAME, derived from the 6809 Simulator V09) 6809 Microcomputer Programming & Interfacing with Experiments" by Andrew C. Staugaard, Jr.; Howard W. Sams & Co., Inc. 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). 990720 EHC: Created this file *****************************************************************************/ #include "debugger.h" #include "konami.h" #define VERBOSE 0 #define LOG(x) do { if (VERBOSE) logerror x;
