PS2NETFS OPERATION AND PROTOCOL
Dan Peori (peori@oopo.net)
Current as of March 6th, 2004
---------------------------------
Communication with ps2netfs takes place on TCP socket 0x4713. A connection is
opened then a request packet is sent. Soon afterwards, a response packet will
be received and the connection closed. Through these simple request/response
pairs more complex functions can be created to do things like copy files to
and from the ps2 itself. For examples see ps2netfs.c in the ps2client source.
