Emulator

Dolphin revision used:
r6676 (64bit), also tried an old one (r5059 (64bit)) to see if the issue was already there which it was ;)

I have the same problem. I can't pass the first snake.

I tried to play the game with Emulated Wiimote. I cann't pass the first snake.

well, there's many delicate wiimote movements in this game, it's hard to get it right with emulated wiimote. but I don't think that has anything to do with the problem at hand here. I passed the first snake even without spin attack.

Please test is r7272 has fixed this issue. The Wiimote timing has been changed in the core.

Issue is still there.

Is Dolphin running at 100% speed when this issue occurs?

Heya, Marcel here...

Yes, it still occurs on recent builds and Dolphin is running at 100% at that time.
However, just to be sure it would be good to have anyone else even confirm this issue, because my Wii got broken before I even started playing this game so I cannot say for absolutely sure if that move is even usable at that time in the game (but the game tells me to use it to get rid of those mites, so...)

Will someone try r1c64b1993de02405e563c5fa13d5b4cb7818c520 (latest master) or later?
A similar issue in another game seems to have been fixed.

I just tried. My spider actually did the Spin Attack. But only twice in a 100 times :) (I don't think it's better than before...I guess it was just a coincidence that it happened now and then I kept trying)...

Heh, I'm glad I'm not the only one. I started to think I might just do something stupidly wrong ^^

I have tested this sort of thing at length with a variety of games. The game instructs the user to to move the wiimote on a 45 degree pivot from left to right in a fashion that the user is looking down at the wiimote. My normal user brain thinks "Hey this maps to emulated "swing"". If that fails, I try emulated "tilt". However, while these are valid logical thoughts, what the game is really looking for is Shake X on the wiimote. If you map the controls this way, you will do the spin attack as many times as the game will allow with your mapped control schema and the games programming.

During the rattlesnake fight, there are several quick time events. One is press Z. That one is pretty easy to figure out. The other two are the 45 degree pivot left and a 45 degree pivot right. Once again, this is NOT swing or tilt. It is Shake X. As long as you map that control and press the same button for both quick times, the spider will dodge left and right.

This is the same sort of thing for the scorpion's dash. The game shows an up and down swing on a 45 degree pivot of the nunchuck like a fly swatting motion. This does not map to swing or tilt either. It maps to Shake. If you map Shake X, Y and Z to the same button for your nunchuck configuration and execute this control while moving, your scorpion will dash.

Also, the scorpion has a dig maneuver. This requires the Shake X on the wiimote and Shake X,Y,Z on the nunchuck as discussed above. With each of these mapped to two buttons you can emulate the scorpion's dig move.

This isn't so much a bug as a confusing connection of control mapping to game instructions. I can't offer good suggestions on an improvement other than maybe including an illustration on the UI of what "swing" and "tilt" really mean. Although, as a fellow coder I know programmatically what is going on can differ from game to game and illustration to illustration.

Anyway, this should help you guys without a real wiimote! Happy Deadly Creatures!
