During object creation netlist tracks the source files which provide
object creation. This is later used e.g. by nltool to create
documentation from source.
These tristate buffers natively support tristate outputs. For use cases
with fixed enable inputs the devices support a parameter
FORCE_TRISTATE_LOGIC which if being set to 1 makes the device behave
like a logic output.
Added additional syntax and consistency checks for tristate outputs.
Updated the example and added dip implementations including
documentation.
- Improve handling of multiple key depressions
- Emulate debounce cycles (emulation partly disabled due to MAME updating inputs only once per frame)
- Add switch closed status flag for sensor matrix mode
Thanks to Aaron Giles who made me think about a different approach.
This is a rewrite from scratch for rom devices. It uses a generic
template to implement rom devices which is used together with a
description struct to define a rom device. This leads to highly
efficient code since all information is available at compile time.
This is also a step forward to support tristate outputs. All rom devices
covered by this approach have tristate or open collector outputs and
thus all code changes to support tristate outputs can now be made
consistently in one file.
ibm5170: New working software list additions
Roberta Williams' Laura Bow in "The Dagger of Amon Ra", Leisure Suit Larry 1: In the Land of the Lounge Lizards (VGA release), Leisure Suit Larry 1: In the Land of the Lounge Lizards (EGA release)
* Reduce duplicates, move virtuals under protected:, use shorter/correct type values, fix spacing
* Convert sprite bank delaying behavior into unique_ptr
* Remove unnecessary device
* move i/o handlers to specific maps, untangle register array usage, to be completed
* Nuke duplicate I/O accesses, rename to iobus_r/w, make go_w to be an actual line
* Fix addqmod & subqmod modulo mask for DSP
* Refactor TOM to host CPU function, and fix GPU irq lv 3 when a GPU object is encountered. Fixes mutntpng and atarikrt booting
* Fix Jaguar irq line to 2, trusted
* Start reworking the blitter
* Relicensed to BSD
