LUA scripting in MAME

MAME: arcade and more

In early 2015 I implemented some LUA scripting primitives in MAME, in order to allow hooking real-time logic to emulation state and drawing overlays like these (Street Fighter 2 hitboxes):

These are some of the enhancements I contributed to the initial LUA engine of MAME to achieve that:

• add API versioning
• add memory-reading capabilities
• add HUD-like capabilities
• expose device state entries

Basic API documentation is available here.
