Argonaut SuperFX core improvements: [Anonymous]

- Added missing register writeback to LMS

- Corrected carry flag behavior in ROL opcode

- Corrected BRA target address calculation (maybe still wrong)

- Corrected LOOP target address calculation

- Made sure that FROM sets cpustate->sreg_idx

- added "pen replacement" blit mode

- fixed palette size

 

Discrete work [couriersud]

- change the way custom modules are handled

- updated drivers mario and dkong accordingly

- minor change to stream input handling

- no more linear lists for nodes. All node processing switched to linked lists.

- module step and reset now only get a node pointer passed

- Added discrete_info * pointer to node

- Only nodes with a step routine actually get processed.

- Fixed a bug: discrete logs did not work since some time

- preliminary parallel task constants; depending on results these may vanish again.

- Overall slight performance increase. dkong 940% to 960%, galaxian 740% to 790%

 

Fix NULL timers crash in the mc6845. [hap]

 

Fixed IM2 interrupt cycles in the Z80 core. [eke]

Added correct U2 sound ROM to the mk3 sets [MK3Fan - Mike]

 

Discrete sound parallel tasks support: [couriersud]

- Introduced DISCRETE_TASK_START, DISCRETE_TASK_END

- DISCRETE_TASK_START: Start a new task. A task is a set of nodes which only depend on input nodes and nodes in the set

- DISCRETE_TASK_END(task_output_node): Marks the end of the task. task_output_node is the node whose output over time should be preserved. This node can be accessed by nodes in the main thread.

- Illustrated the concept in the dkong discrete emulation. This also has been enhanced to buffer DAC output.

- Discrete tasks now support multiple task output nodes

 

Further discrete changes: [couriersud]

- DISCRETE_OUTPUT now is a stepping node.

- DISCRETE_STREAM_INPUT now advances input pointer in step.

- More linked_list usage.

Fixed B-Rap Boys sound banking [Phil Bennett]

 

Sigma Poker: Fixed duplicated definition of Hold 2 button. Added the missing Hold 3 button. [Roberto Fresca]

 

Continued discrete sound system "list-ification": [couriersud]

- No more constraints on number of input and output nodes

Removed osd_is_bad_read_ptr function. [Aaron Giles]
