      Argonaut SuperFX core improvements: [Anonymous]
      - Hooked up Branch instructions
      - Fixed numerous SuperFX core bugs.
      - Improved disassembler to more gracefully handle ALT* opcode effects.
      - Corrected instruction behaviors: STOP, SUB, SBC, SUBI, CMP
      - Added LSR and ROL opcodes
      - Updated instructions to use the safer superfx_gpr_write: LOOP,
      PLOT, INC, DEC
      - 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
      - Disabled RAM/ROM clocking, going with instant transfer for now
      - Understood and re-enabled pipelined instruction architecture, Star
      Fox runs farther
      - Fixed a ridiculous typo in ROL instruction
      - Fixed overflow flag calculation on ADDI / ADCI
      - Fixed lack of register reset after ADD / ADC / ADDI / ADCI

      tmaster.c update [Luca Elia]
      - implemented carts banking and multiple EEPROMs
      - 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]

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

      Discrete sound parallel tasks support: [couriersud]
      - 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.

      - Made pbst30b a clone of pbst30 and added program versions to the
      name, IE: Pit Boss Supertouch 30 (9234-10-01)

      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
      - input nodes now make use of a context
