| 12 | 12 | increment twice per coin. |
| 13 | 13 | - clean up Avengers protection; it currently checks against hard-coded program |
| 14 | 14 | counter rather than behaving as a memory-mapped black box. |
| 15 | - accurate music tempo (audiocpu irq freq) |
| 16 | - accurate video timing, raw params |
