Added serial interface to gaelco3d hardware. In machine/gaelco3d there are instructions on how to compile and run two synchronized instances of mame to play gaelco3d games. This requires shared memory and currently only works on UNIX. It is disabled by default.
This is a proof-of-concept commit. It works but is far from stable. Synchronization between two mame processes is *somehow* (trying to avoid hacked) in. However, this is not HLE. Shared memory is used to share the serial interface lines. If the shared memory code is not enable, stub functions are used. If you set the link mode to master or slave, "not linked" will be shown in the game. That's better than the previous hang. Please, no whatsnew.

|

Couriersud, early 2010
|
||||
|
||||
Not all lines are fully understood. There is some handshaking going
|
||||
on on send which is not fully understood. Those wishing to have a look
|
||||
at this:
|
||||
|
||||
Serial send: 0x1fca (radikalb, 68020) 1866e (surfplnt)
|
||||
Serial receive: 0x1908 (radikalb, 68020) 185ae
|
||||
|
||||
The receive is interrupt driven (interrupt 6) and the send is
|
||||
initiated out of the normal program loop. There is the chance
|
||||
of race conditions in mame.
|
||||
|
||||
To run two instances of radikalb on *nix, use the following
|
||||
|
||||
a) Uncomment SHARED_MEM_DRIVER below
|
||||
b) Open two terminals
|
||||
c) In terminal 1: mkdir /tmp/x1; cd /tmp/x1; /path/to/mame64 -np 2 -mt -rp /mnt/mame/romlib/r -inipath . radikalb -w -nomaximize -inipath .
|
||||
d) In terminal 2: mkdir /tmp/x2; cd /tmp/x2; /path/to/mame64 -np 2 -mt -rp /mnt/mame/romlib/r -inipath . radikalb -w -nomaximize -inipath .
|
||||
e) Set one instance to be master and one to be slave in service mode
|
||||
f) Have fun
