Changelog:
- fc/controller: added ControllerPort class; removed Peripherals class
- md/controller/gamepad: removed X,Y,Z buttons since this isn't a
6-button controller
- ms/controller: added ControllerPort class (not used in Game Gear
mode); removed Peripherals class
- pce/controller: added ControllerPort class; removed Peripherals
class
- processor/spc700: idle(address) is part of SMP class again, contains
flag to detect mov (x)+ edge case
- sfc/controller/super-scope,justifier: use CPU frequency instead of
hard-coding NTSC frequency
- sfc/cpu: move 4x8-bit SMP ports to SMP class
- sfc/smp: move APU RAM to DSP class
- sfc/smp: improved emulation of TEST registers bits 4-7 [information
from nocash]
- d4,d5 is RAM wait states (1,2,5,10)
- d6,d7 is ROM/IO wait states (1,2,5,10)
- sfc/smp: code cleanup to new style (order from lowest to highest
bits; use .bit(s) functions)
- sfc/smp: $00f8,$00f9 are P4/P5 auxiliary ports; named the registers
better
