I don't know if this game has come out in Europe or the the US yet... I saw no sign of it in London a month ago... but I picked it up in Japan a couple weeks ago. This game comes with a "slider" that's basically a wedge shaped optical mouse that jams into slot2 of the DS. I can take photos if anyone wants them.
I was wondering if anyone had worked out how to access this thing yet? I lost my R4 on a plane and haven't gotten around to getting a new one, so I haven't been able to do anything with it myself.

I'd like to see some info about this. Could be useful for various things depending how it works.

Sounds neat, please do post some photos. Maybe even a video?

Thanks, yeah that looks pretty neat. I've never seen anything about it before, so I assume its going to stay Japan-only.

To be honest the game is complete kack. But for 4000 yen with the mouse thing I suppose it ain't bad. The mouse part is pretty well built, and is an offical nintendo device, i.e. it has their logo on it.
As soon as I get another R4 I'm going to build an etch-a-sketch app with it or something :)

I don't think anyone is interested... but I'll post my findings here anyhow;
Pins in use on the Slot2 board;
/WR -- Used as a clock for the flip-flop. So writing to slot2 causes a clock.
/RD -- Runs into the nand, it goes into a gate on the nand.. I'm not sure what the other input on that gate comes from. But the output goes into one half of the gate connected to AD19
AD0 -- Not sure, I suspect it goes in to the nand..
AD1 -- Second input of the flipflop, from tracing the circuit it seems to be connected to the Serial IO CLK signal on the A2030.
AD2 -- Third input of the flipflop, Bringing this high and clocking the flipflop brings the A2030 to life. So I think this is connected to the PD signal of the A2030 which according to the data sheet is used for syncing with the host MCU and powersaving..
AD3 -- Forth input of the flipflop
AD8 -- runs into the rumble section of the board.. pulling it high and clocking the flip-flop will turn in on, low/clock off again.
A19 -- runs into the nand, the output of this gate runs up to the buffer I think.
Parts on the boards;
"Agilent ADNS-2030 Low Power Optical Mouse Sensor"
"7400 - Quad NAND"
"74273 - Octal D-Type Flip-Flop"
"74125 - Dual Bus Buffer"
Without some basic equipment like a multimeter or logic probe, I can't do much more. I know that the A2030 needs a clock signal via SIOCLK that is apparently on AD1. I have the instruction set for the A2030 here, so if I could work out what the remaining pins do I could start programming the A2030; I think one is for the SIO pin itself and the other two are for controlling the direction of the SIO, i.e. from DS to A2030, from A2030 to DS. I think controlling the direction of SIO has something to do with A19... it's on a non-muxed pin (address or data) for a reason. I think the reason is that if you read from slot2 offset+a19 offset you put the bus into read mode? /rd is going into the nand as well..
