Nintendo Family Computer & Entertainment System controller ports
|
|
and Family Computer expansion port emulation
|
|
|
|
Here we emulate in fact 3 different kind of ports, which are
|
|
connected to different bits of memory locations $4016 and $4017:
|
|
- NES controller ports: these are hooked to bit 0,3,4 of the
|
|
corresponding address ($4016 for port1, $4017 for port2)
|
|
- FC controller ports: these are only hooked to bit 0 of the
|
|
corresponding address (so that e.g. a NES Zapper could not
|
|
be connected to a later FC AV model, because its inputs
|
|
would not be detected)
|
|
- FC expansion port: this is hooked to bit 1 of memory location
|
|
$4016 and bits 0-4 of $4017
|
|
To make things a little bit more complex, old FC models have
|
|
controllers hardwired to the unit, and the P2 controllers are
|
|
directly hooked to bit 2 of $4016 (for microphone inputs).
|
|
|
|
Even if the controller port and the expansion port are
|
|
physically different (the FC expansion is a 15pin port, while
|
|
the controller ports are 7pin), we emulate them as variants of a
|
|
common device, exposing the following handlers:
|
|
- read_bit0: for bit0 reads, which are typically used for serial
|
|
inputs from controllers
|
|
- read_bit34: for bit3,4 reading, expected to be at the correct
|
|
offset (but we don't currently check for read_bit34 & 0xf8==0)
|
|
- read_exp: for reads going through the expansion, with a offset
|
|
parameter to decide whether we are reading from $4016 and $4017
|
|
- write: to acknowledge writes to $4016
|
|
|
|
The driver emulation will take care to only call the correct
|
|
handlers they have hooks for: Basic usage is that the expansion
|
|
port calls read_exp, FC ctrl ports call read_bit0, and NES ctrl
|
|
ports call both read_bit0 and read_bit34. However, to cope with
|
|
the original FC microphone, we have a one-off read_bit2 handler
|
|
called by the second controller.
