I love me some DS hacks. DS rules!

Typo: “mocrocontroller”

Pretty cool. I’d like to see someone implement *real* force feedback. ie: a heavy weight inside the device is shifted left/right and forward/back when you’re turning, accelerating, braking, shooting, etc. Imagine playing a motorcycle game where you need to physically lean into the turns.

Rumble != forcefeedback
Forcefeedback is when you press a controller and it pushes back like steeringwheels and joysticks can have, rumble is just vibration and another thing altogether, and obviously much cheaper to make and easier to cram into small controllers and needing less power.
So please don’t use the wrong term, it only causes confusion and a world without forcefeedback because if the manufacturers think it’s the same to people they will pick the simple and cheap solution instead of supplying and implementing the real thing.

Nintendo did an official version of this a long time ago, and it isn’t dependent on the audio feed. I know that at least metroid prime hunters and metroid prime pinball supported it, possibly others. The fact that you can find them for $1.25 on ebay right now just makes the lack of a hack here all the worse.

I really like the SNExbox method of force feedback: it watches for the actual game condition, and triggers the rumble accordingly. It works much like a game genie, PEEKing at memory addresses for the right set of conditions. It takes about as much time to program as finding game genie codes, but it’s very effective.

I bet this could be done entirely in software, given enough effort.

neat!

my $0.02 worth, obtain two vibrating pancake motors from a defunct samsung or motorola ‘phone.

these can be run at three distinct speeds using a voltage doubler run off a PIC pin, allowing far more of a range of signals to be sent by the host.

they are also handy for haptic feedback gloves for the same reason.
