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

     4 General issues

     5   - No dynamic recompilation yet

     6   - Slow (not performance optimized yet at all. See above).

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

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

    10 SH4 Core

    11   + Base instruction set  (Complete?)

    12   - No MMU support (address translation, TLB, etc)

    13   - no FPU exceptions

    14   - Not remotely cycle-correct timing

    16 SH4 On-chip peripherals

    17   BSC

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

    19   CPG

    20     * Complete?

    21   DMAC

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

    23   INTC

    24     * Complete?

    25   RTC

    26     * Not implemented

    27   SCI

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

    29   SCIF

    30     * Complete? (not heavily tested)

    31   TMU

    32     * Complete?

    33   UBC

    34     * Not implemented

    36 AICA SPU

    37   ARM core

    38     + Base instruction set (Complete?)

    39     - No thumb support

    40     - No system coprocessor support

    41     - No cycle-correct timing

    42   DSP

    43     + Basic sound generation

    44     - No waveform support

    45     - No LFO support

    47 PVR2 GPU

    48   TA

    49     - Functionally complete

    50     - Some bugs/error behaviour not implemented

    51     - No timing support

    52   Render

    53     + Basic opaque and translucent polygon support

    54     + Depth buffer, alpha blend, most poly modes

    55     - Basic translucent poly sorting

    56     - No modifier volumes

    57     - No fogging

    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
