[linuxdc-dev]Progress/lack of progress wth Sega Puru Puru Pack

[Adrian M. <ad...@mc...>]

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.
