I'm not sure how the controls are on iClassic, so I can't weigh in on the Wiimote's compatibility with iClassic.

I waited for months for them to finally come out with the version that supports controllers other than the iControlPad and iCade. It finally came out about six months ago, but I discovered the Wiimote wasn't very functional with iEra.

Mainly because of the dual analog control scheme on iEra. The Wiimote alone doesn't have enough buttons to work on iEra. The only semi-effective method I found was to set the directions to the D-Pad(which is a rather clumbsy movement control with this type of game) and fire with your hand on the iPad(Which repeatedly switches the orientation as you move around, hence messing up the dpad control presets.)

iCade would probably have the same problems, because of its controls.

Blutrol's an excellent program, but if you want to use a controller with your iPad/iPod on iEra, I would suggest using it with the either iControlPad or PhoneJoy(Pretty much a generic PS2 controller that's compatible with mobile devices).

There was talk about Blutrol becoming compatible Wii Classic and Sixaxis controllers in later versions, but after seeing how long it took to come out with the Wiimote support, I wouldn't hold my breath. (I waited several months). If Wii Classic Controller is ever supported, this thing will rock.

Sixaxis controller doesn't really warrant my respect on Graal because I tried it on the PC Version back in 2007-ish. While it has a nice feel to it, it's analog sticks aren't as responsive as the XBOX or Wii Classic Controllers.

Again, I'm not sure what the controls on iClassic are, so my review could be null. But if they're anything like iEra(dual analog), then everything in this post is applicable.

Edit:
Judging from the snapshot, it doesn't look like iClassic has dual analog controls, so this may work with the WiiMote, if you don't mind d-pad controls.
