Accelerometer with Keyboard/Mouse

12-11-2009, 07:05 PM #1

I want to play a game (Suzumiya Haruhi no Gekidou) that uses the accelerometer, but I don't have a real Wiimote. Is it possible to control the accelerometer with the keyboard and/or mouse?

This is basically what I need to do:
Hold the Wiimote in front of me in the upright position, then move it left/right/top/bottom while keeping it upright.

Are "Tilt and Swing" related to the accelerometer? With r4674 (32-bit), I set "Tilt and Swing" to "Keyboard" in "Wii Remote Plugin Configuration" and then tried the "Roll Left/Right" and "Pitch Up/Down" buttons and nothing happens. I'm guessing rolling and pitching isn't for translational movements.

This is my first time using Dolphin-emu Blush

. Any help would be highly appreciated!

It can be mapped to joypads and R/L "sensitive" buttons of controllers, so you don't need a wiimote. But I don't think anyone has made the different wiimote positions as mapped to keyboard.

Btw is it a dance game? Can you do Hare Hare Yukai?

Thanks for your tips

It is a dance game, although you don't need to move around
Hare Hare Yukai is the 8th song; but the "steps" here are much easier than the actual dance

After spending a lot of time trying different options and builds, I finally figured out how to get Suzumiya Haruhi no Gekidou to work in dolphin. I hope this helps anybody who'd like to play the game, or games that use the accelerometer, without a Wiimote.

First of all, choose a suitable build:

r4694 doesn't work
r4681 works
r4525 doesn't work

And set these:

Disable Connect Real Wiimote
Set Tilt and Swing to Keyboard
Set Roll and Pitch to Free Swing
Assign keys to Roll and Pitch

The timing of the accelerometer is good enough to achieve S-rank in the first song Blush

Some (non-critical) issues:

Audio (alc888b) is choppy in XP, so I play in Vista
Frameskipping sometimes causes flicker in the background of the dance scene, and sometimes gives a blank screen, but luckily I don't need frameskipping in standard resolution
MSAA causes flicker during screen transition
MSAA doesn't apply to EFB copy, so the character outlines looks really bad in higher resolutions
Copy EFB to system RAM causes an offset in the character outlines, so use Copy EFB to GL Texture instead
2X resolution doesn't work: about one-fifth of the screen on the right hand side is bad. (Let me try to describe it... if you consider the whole screen as 1280 vertical lines, each being 1 pixel wide and 960 pixel tall, then about 200-300 lines on the right are always identical. It's like you grab a line and drag it horizontally to the right, overwriting the whole area with the pixels of the line.)
