How to build Mog's optimized CMI2x (in a nutshell)

1. Download the sourcecode from here:
github.com/Moo...
2. Download the source files for the Motorola 6840PTM here;
github.com/Moo...
github.com/Moo...
and copy the files to 'mame-cmi-optimization\src\devices\machine\'
3. Read the instructions on how to set up the compiler environment for MAME here:
docs.mamedev.o...
4. Set the following options in MAKEFILE:
OPTIMIZE=3
LDOPTS=-FUSE-LD=LLD
DEBUG=0
PROFILER=0
SYMBOLS=0
STRIP_SYMBOLS=1
5. Compile MAME with ARCHITECTURE FLAGS to optimize the code for your CPU:
A list of the x86 options for the GNU C++ compiler can be found here:
gcc.gnu.org/on...
Example:
make SUBTARGET=mame SOURCES=src\mame\fairlight\cmi.cpp ARCHOPTS="-march=ivybridge"...
6. Download the preconfigured MAME-CMI2x program folder from here:
drive.google.c...
and copy your mame.exe into this folder.
When using a CPU with a single-thread performance of less than 3,000 MOps/s (Passmark PT11), it is recommended to additionally remove some parts from the emulation.
Some already optimised source files and a few add-ons are available here:
