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)
11 + Base instruction set (Complete?)
12 - No MMU support (address translation, TLB, etc)
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 - Functionally complete
50 - Some bugs/error behaviour not implemented
53 + Basic opaque and translucent polygon support
54 + Depth buffer, alpha blend, most poly modes
55 - Basic translucent poly sorting
59 + All texture formats supported except bump maps
63 + Supports Ident, Set feature, and Packet (and no other IDE commands)
64 + Supports PIO and DMA modes
66 + Supports Test ready, Ident, Read TOC, Read Session info, Sense request, and Read CD
68 - other 20-odd commands not supported
72 + Standard DC controllers
74 - No support for other controller types (keyboard, mouse, gun, etc)
