Known
Issues (v1.01):
- initialising
joysticks with the SDL multimedia
library will stop WiiYourself! detecting
wiimotes that were available at the
time. Connect() those wiimotes
before calling
SDL_InitSubSystem(SDL_INIT_JOYSTICK) (thanks
Andre).
Tested:
| Vista
32bit: |
MS
built-in BT stack |
supports
HID writes only, audio frequently warps |
| |
Toshiba BT stack v5.10.12 /
v6.10.10 |
supports
WriteFile() only, some audio glitches |
| Win2k: |
Widcom BT stack v1.4.2.8 |
supports
WriteFile(), ... |
Ways
you can help:
Hardware:
- donate a Wiimote,
Classic Controller, Balance Board or Guitar
Hero peripheral (condition doesn't matter
as long as it works).
Testing:
- general testing & feedback (including Bluetooth
stack compatibility reports)
- Classic Controller testing (I don't have one)
- multiple Wiimote testing (I only have one)
Features:
- any improvements/features/ports to new
compilers/docs etc. welcome.
- how to auto-pair the Wiimote when the Power
button is held down?
Apparently it can be made
to work on the BlueSoil stack
using its native API,
but I'd want a generic way...
Audio
code:
This is what it sounds
like on my Vista/Toshiba setup:
(note sometimes it's more
stable & sometimes the audio vanishes
completely until you retrigger it a few
times)
.wav version (6.6mb)
.wv version (lossless Wavpack, 4.6mb)
- ADPCM
variant doesn't seem exact (try Sine wave
sample in demo)
and/or
- Occasional glitches/dropouts/phase
inversions? (worse with HID writes which
seem more jittery) -
a) are the speaker
frequencies exact?
b) ways to improve
output and/or smoothe wiimote sample
buffering?
- 'Volume' seems to actually influence
decoding in some way (values over 0x40
totally warp ADPCM playback and seem to
remove low-intensity sound like a noise
gate...).
- is some ADPCM state initialisation
required? most likely...
Stuff
that'd be real handy:
- better wiimote position/orientation
estimation.
(for the basics read
this,
and for a possible approach read
this).
ideally should use IR too.
