1212    TODO:
13   - walk the dog
13   - Understand what the 0x400000c reads on SH-2 really do.
14   - Remove SH-2 watchdog hack, if we ever bother about it ...
1415   - improve sound emulation
15    - i8237 purpose is unknown, might even not be at the right place ...
16    - i8237 purpose is unknown (missing ROM for comms?).
1617   - verify zooming etc. our current algorithm is a bit ugly for text
