Open Questions
These are the points that are missing from the docs. In subsequent
releases you'll see those questions crossed out, when we found out
an answer and questions added, when we became more puzzled.
If you can help us out on any of the following points, please
send us mail. We also take source code gladly. Please no ripped
cartridges though.
- What is CLK1, CLK2, CHROMA_CLK used for ?
- How is the Z-Buffer organized ?
- How do you turn on interlacing ?
- A good explanation of the MEMCON registers. You can slow the
blitter with those. Can you also speed it up ?
- Is there a way to speed up blitter source reads ?
- Interrupt sources. So far VBLANK, OP and Timers are covered only.
Specifically
- Can the blitter generate an IRQ ? (which one ?)
- Can the GPU generate an IRQ ? (which one ?)
- Can the DSP generate an IRQ ? (which one ?)
- Can the 68K generate an IRQ ? (which one ?)
- Where are the network registers ?
- Is there JAGPEG code in the boot ROMs ?
- Is the GPU also suspended, when its processing the same IRQ as
the 68K ?
