Thanks to Action Replay, Nitro Hax, and the fine folks at kodewerx.net (kenobi especially), you can now play your commercial games with tilt control.
Some Action Replay/Nitro Hax codes have been written that map the X and Y acceleration of the DS Motion Pak to Left, Right, Up, and Down button presses. It works as follows:
1) Overwrite all the pointers to 0x4000130 (REG_KEYINPUT) with a pointer to an unused memory location.
2) Read REG_KEYINPUT and the DS Motion Pak.
3) Combine the key states from REG_KEYINPUT with key states calculated from the measured tilt.
4) Write the new key states that include tilt to the specified unused memory location.
Voila - the game uses key states that are calculated from the tilt measured by the DS Motion Pak.
Once the game has started, press Start+Select to enable tilt sensing. Keep in mind that this is the first release - most likely newer, better versions will be released in the future. It has been tested and confirmed to work on Mario Kart DS (AMCE) and Tony Hawk's Downhill Jam (AWKE), and it probably works on most games.
Don't ask if it works on roms - I only have legitimate game cartridges.
Here are the codes:

This is cool, but I can't imagine that moving the system up/down/left/right to simulate the digital pad feels all that super fantastic, at least not in the two games you mentioned. There might be some that it would work well with, though none are jumping into my mind at the moment.
What would be really nice is some more game-specific codes that have controls mapped in ways that make sense to the game. So Z-rotation could be used for the wheel and Z-acceleration for shifting in a racing game.
Would it be possible to map the motion pak to touchscreen inputs? Then you'd have analog for analog and it might work really well in certain games (I'm thinking especially of some of the games on the AtariMix collection, though there's probably plenty of others).
I'll definitely be interested to see how this hacking develops. Could end up being really really cool for certain games.

one step closer to tilt mario64. I suppose it might be possible to add support for the 'run' button, so tilting a certain angle will walk mario and tilt further he will run?

But would that necessarily be a desirable thing? There's a reason that Super Mario Galaxy uses the Control Stick instead of the Nunchuk's tilt sensor.

A touchscreen one would be a bit more useful, methinks. Cool anyhow.

Would that be possible Keith? somehow set the motion pak to 'drag' the stylus rather than setting a button press? would bring my tilt mario64 dream a little closer.
*Wish i was a 'super leet' coder so I could do things like this myself, but alas I'm far to lazy to learn.
[slightly off topic] Anyone know how I can get a free motion pak, are there any competitions around offering them as a prize or something? I have the slot-1 version, but thats no good for this.

#146295 - KeithE - Sun Dec 02, 2007 4:05 am
Probably possible to map motion pak to stylus. It is a matter of finding the location in RAM of some in-game variables that are controlled by the stylus and updating them with motion pak outputs.
One challenge would be how do you tell the game whether or not the stylus is down - just touch the screen anywhere (maybe with a finger), then tilt to move? Other ideas?
I'm working on giving "analog" control to games that use the digital D-pad by attempting to use a technique called Pulse Width Modulation (PWM). Basically, the pad would be pressed on and off very quickly, with the percentage of time that it is pressed increasing as you tilt more. I have no idea how it will feel or how the game will react to it, but it will certainly be interesting to try.
Of course, game specific mappings will yield the best results. Unfortunately, I don't own very many commercial DS games - most of my DS game playing is homebrew!
#146296 - tepples - Sun Dec 02, 2007 4:12 am
You'd need some sort of violence mod (where shovel and axe actually do something to neighbors) to turn pacifist sandbox into gangster sandbox. I don't even want to contemplate how many AR/NH lines that would take ;-) But seriously, pressing a direction for soft tilt and pressing L+direction for hard tilt would work for ACWW.
A lot of the touch-screen-hooking code would be similar to "sprite following" in PocketNES or other emulators. For example, in Super Mario 64: when in game mode, set the pen down bit to whether or not the tilt is in the dead zone. When the tilt leaves the dead zone, put the pen down in the middle and then set the stylus position to the tilt vector.

Here are codes that do analog control - tilt a little to turn a little, tilt a lot to turn a lot. It works on games that use the D-pad by "pressing" the buttons on and off very quickly.
It makes the menus VERY hard to control, so I added a feature that if you hold SELECT it turns off the tilt sensing. Hold SELECT when the game is in a menu, then you can use the D-pad to choose your option.

the R6 Gold is a normal flashcard with ?SD and a motioncard the same time
