     2 ==============

     4 General issues

     5   - Slow

     6   - No I/O timing whatsoever except for video events.

     7     (ie DMA, rendering, GD-Rom operations need to take > 0 ms to complete)

     9 SH4 Core

    10   + Base instruction set

    11   - no FPU exceptions

    12   - Not remotely cycle-correct timing

    14 SH4 On-chip peripherals

    15   BSC

    16     * Not implemented except for PCTRA/PDTRA, and that part is quite dodgy.

    17   CPG

    18     * Complete?

    19   DMAC

    20     * Implemented to extent needed by ASIC DMA, not fully complete

    21   INTC

    22     * Complete?

    23   RTC

    24     * Not implemented

    25   SCI

    26     * Not implemented (not even hooked up in the hardware?)

    27   SCIF

    28     * Complete? (not heavily tested)

    29   TMU

    30     * Complete?

    31   UBC

    32     * Not implemented

    34 AICA SPU

    35   ARM core

    36     + Base instruction set (Complete?)

    37     - No thumb support

    38     - No system coprocessor support

    39     - No cycle-correct timing

    40   DSP

    41     + Basic sound generation

    42     - Really bad sound

    43     - No waveform support

    44     - No LFO support

    46 PVR2 GPU

    47   TA

    48     - Functionally complete

    49     - Some bugs/error behaviour not implemented

    50     - No timing support

    51   Render

    52     + Basic opaque and translucent polygon support

    53     + Depth buffer, alpha blend, most poly modes

    54     + Opaque shadow volumes

    55     - Basic translucent poly sorting

    56     - Y-scaler

    57     - No modifier volumes

    58   Texture

    59     + All texture formats supported except bump maps

    61 GD-Rom

    62   IDE interface

    63     + Supports Ident, Set feature, and Packet (and no other IDE commands)

    64     + Supports PIO and DMA modes

    65   GD-Rom interface

    66     + Supports Test ready, Ident, Read TOC, Read Session info, Sense request, and Read CD

    67       commands

    68     - other 20-odd commands not supported

    70 Maple

    71   + Maple bus complete?

    72   + Standard DC controllers

    73   - No dynamic timing

    75 Network

    76   - Not implemented
