- To Do (mainly in order of priority):
-
- Search and destroy the existing bugs.
-
- Fix "randomness" of flags; particularly Sign of Bit 7,s
-
- testreq at GoLowBuf (?)
-
- Undefined-opcode exception, and other possible uses of a general
- exception handler call.
-
- Optimisations for higher processors.
-
- Better documentation on how to write instruction routines,
- including full descriptions of the implementation-dependent
- instructions (flags and such).
-
- User patching of instructions.
-
- Consider return upon Halt, pulling Z80 HALT line low.
- Would that be a general exception, or a separate thing?
-
- Implement interrupt mode 0? How then?
-
- DMA-request to make sure external write to memory is between instructions?
- (Simply use Exit? Slow, but...) This also a general exception?
