I have been trying to get this to work all weekend - with no luck :-<.
This is the code that sends packets to the maple bus:
static void play_puru(struct dc_purupuru *puru)
{
/* Play the selected effect */
struct mapleq *play = &(puru->data->mq);
play->command = 14;
play->length = 2;
((unsigned long *) (play->recvbuf))[0] =
cpu_to_be32(MAPLE_FUNC_PURUPURU);
((unsigned long *) (play->recvbuf))[1] = "A VALUE";
play->sendbuf = play->recvbuf;
if (maple_add_packet(play) != 0)
DEBGM("Could not add packet\n");
}
Here are the different results for different "A VALUE"s
/*

Works means that the maple bus returns a command acknowlegement (7), fails
means the bus returns a -4 (resend command). The NAKI PPP always seems to
return a 7.
Nothing I've done actually makes the SEGA one vibrate (this is what no output
means above).
Can anyone see a pattern? Given that the NAKI pack vibrates normally with
games then it must be the case that there is a condition where it's behaviour
and the SEGA behaviour are the same.
The only thing I can see is that bit 4 needs to be on as a minimum condition
for the SEGA pack.
