| 21 | | In non-debug mode it runs for a few seconds then freezes requiring MESS |
| 22 | | to be forceably closed. In debug mode, it can be seen that a processor |
| 23 | | exeception occurs, although sometimes the cpu 'just stops', causing a |
| 24 | | MESS freeze. Obviously the real machine doesn't do these things. |
| 21 | This system uses a number of unemulated opcodes (A0xx). Our M68000 core |
| 22 | mishandles this scenario, doing a random jump to nearby code. This |
| 23 | continues, filling up the stack, and eventually causes a total freeze. |
