| nkeynes@176 | 2 | ============== |
| nkeynes@176 | 3 | |
| nkeynes@176 | 4 | General issues |
| nkeynes@176 | 5 | - No dynamic recompilation yet |
| nkeynes@176 | 6 | - Slow (not performance optimized yet at all. See above). |
| nkeynes@176 | 7 | - No I/O timing whatsoever except at a timeslice level for audio/video. |
| nkeynes@176 | 8 | (ie DMA, rendering, GD-Rom operations need to take > 0 ms to complete) |
| nkeynes@176 | 9 | |
| nkeynes@176 | 10 | SH4 Core |

| nkeynes@176 | 12 | - No MMU support (address translation, TLB, etc) |
| nkeynes@176 | 13 | - No user-mode support |
| nkeynes@176 | 14 | - Not remotely cycle-correct timing |
