[RELEASE][3rd party sources included :D] LocoRoco Motion Plugin v0.99 = Next-Gen

Mr305 · 12-26-2007, 09:24 AM

Here's a major update from previous version.

This version almost all problems that existed in the previous 0.8 SWC "SomeWhatCrippled" version.

You can also try the LocoRoco demo's; you donot have to own the game to try this.

Requirements:
-------------

1) Neo Motion Kit
2) CFW atleast v3.71 - due to NID compatibility.

Changelog:
----------
1) Added audio Fix; Audio works perfectly along with motion for perfect LocoRoco game experience.
Thanks to ps2dev members.
2) Added a check, wherein the plugin self-terminates with a message, if Motion Kit is unplugged or not plugged in
before the game begins or due to failure in initialization; hence if anything fails, you can still
play the game unlike previous version which caused "unusably sluggish behaviour".
3) Added a Jump function but something isn't right. Tilt forward and then backward.
[This will most probably be removed in next version if I can't figure out the problem]
4) Substantially improved chances of succesfull initialization. Failure rate - 1 in 10 times.
5) Reduced CPU usage - removed unused stuff / Z axis reading / other calculations

Videos Illustrations:
------------------

Latest Video with audio & initialization failure / disconnection notification

Tutorial / How to use the plugin

Fast Paced action video

Additional Notes:
-----------------
1) After muting and disabling by using Note button, audio doesn't re-enable, Press Vol Up or Down.
2) You'll see a slight delay when you change the volume -- it's normal.

Any suggestions for improvement welcome. Enjoy.

Note: Put "REAL USER" in your post let me know you have actually tried this.

You know, you make it really hard not to spend all of my X-mas cash on buying that peripheral and game.

I wish they would make a slim version

Pity you didn't include the code - especially since you stitched most of it up from various apps. I like the way you *reused* the SceCtrlData structure in conjunction with count to initialize your function

Good job!

Here is a quick and dirty reverse of it. Not compilable as is, and contains a few volountary errors to make it QJ-proof.

Code:

Nice man.. I was 'bout to release source with next release.

Anyway, Great skill ya got

EDIT: Before you claim "Stitch", Ofcourse it uses Psplink's ApiHook sources & vshblit.c/h

The code is far less complex than I had imagined :P
@adrahil: Would like to know if you're able to reverse my motion kit driver too when I release it first :P Nah, don't want to waste your time, I know you could

PS: Not much left before the first release, only one minor bug and writing a readme
