Some additional insight
I'm looking for an answer as well but it seems I might have gotten further than most are getting on this thread.
My setup:
Acer Iconia A100 Tablet
Wii Remote and Classic Controller
Wii Remote IME by Ryan Frawley (Available on the market for like $4 and change)
There is a video and a quick explanation in the first few Google results if you search Wii Remote IME Android, I'd post them but I got an error that I didn't have enough posts yet to do an outside link
One thing that isn't mentioned in either place is that if you are using an add-on controller (Nunchuck or Classic) they'll only show up if they are connected to the Wii Remote before you pair the Wii remote.
Once connected, I was able to go into the controller map and adjust the Classic controller settings to use the keyboard controls I found out by using a Logitech "Keyboard for Android 3.0" (really, that's the model name on the back, I doubt it matters but I found a regular bluetooth keyboard with a windows key on it had some different key mappings though we're not using any non-standard keys.)
Some of the basic controls are:
Up/Accelerator - Up Arrow
Down/Reverse - Down Arrow
Left - Left Arrow
Right - Right Arrow
Sprint/Accelerator - 1
Shoot - 2 (if held, auto-targets closest target)
Jump/Reverse - 3
Enter/Exit Vehicle - 4
Change Radio Station - 5
Change Weapon Next/Look Left in Car - 6
Change Weapon Previous/Look Right in Car - 8
So far, it works, however the buttons appear to be getting "stuck". What I mean for instance is I start walking left and now I'm stuck walking left and can't stop. If I press sprint, it will start running left which I can't stop either. I suspect this is a bug in the IME program or potentially an issue with the game. I will post more if I can get this working as the game is unplayable with a keyboard as you can't easily control the camera, walk, aim and shoot. Playing with only the touchscreen is very clunky as well and really any game that needs analog sticks can't be adequately simulated using the touchscreen IMHO.
I'll post more as I discover it but I really want to get this working so if anybody has ANYTHING to add I'm begging you, add it!
***Edit - After rebooting my tablet and doing the following, the "stuck" problem appears to have resolved itself:
1. Start GTA III, enter your game and press home
2. Start Wii Remote IME
3. Set IME to Wii Remote using settings page in program
4. Go back to GTA from the notification area
5. Test it out, it will probably work!
It also makes sense to point out that I'm using the option to switch back to a different default IME on exit which is the reason I used the order that I did. If you use an automatic task killer, it probably makes sense to make an exception if you can for the Wii Remote IME program in order to keep it open if you want to use that option.
