5 - No dynamic recompilation yet
6 - Slow (not performance optimized yet at all. See above).
7 - No I/O timing whatsoever except at a timeslice level for audio/video.
8 (ie DMA, rendering, GD-Rom operations need to take > 0 ms to complete)
11 + Base instruction set (Complete?)
12 - No MMU support (address translation, TLB, etc)
13 - No user-mode support
14 - Not remotely cycle-correct timing
16 SH4 On-chip peripherals
18 * Not implemented except for PCTRA/PDTRA, and that part is quite dodgy.
22 * Implemented to extent needed by ASIC DMA, not fully complete
28 * Not implemented (not even hooked up in the hardware?)
30 * Complete? (not heavily tested)
38 + Base instruction set (Complete?)
40 - No system coprocessor support
41 - No cycle-correct timing
43 + Basic sound generation
49 + Quick-n-dirty hack job to store the TA command lists in the poly
50 buffer and nothing else. Not remotely correct.
51 - Doesn't support 16-dword vertexes
53 + Basic opaque and translucent polygon support
54 + Depth buffer, alpha blend, most poly modes
55 - No translucent poly sorting
58 - No specular highlight
59 - No 16-dword vertexes
61 + Most texture formats supported
62 - No support for VQ decompression
66 + Supports Ident, Set feature, and Packet (and no other IDE commands)
67 + Supports PIO and DMA modes
69 + Supports Test ready, Ident, Read TOC, Read Session info, Sense request, and Read CD
71 - other 20-odd commands not supported
75 + Standard DC controllers
77 - No support for other controller types (keyboard, mouse, gun, etc)
