Exciting race between aa and Jumpin' Jack!
Hey the Wii can do 3D!
This is literally a first version as in "you'll have a bumpy ride in front of you" (much like in Stunt car racer). This version features the all-important joystick input, so games are actually playable and the first wiimote acts as both mouse (point at the screen and press the A key for the button) and joystick (the directional buttons plus 2). The first wiimote is also configured to generate 'a' when you press + and return when you press -, just to show what can be done with the UAE configuration file. Home is for the menu.
I must say I'm impressed with UAE (OK, the country also features some impressive features so this goes for both). I thought I would have to spend a lot of time on the wiimote input handling, but it turns out that nearly everything is possible to setup using the configuration file. The only source code modification I had to make was to add handling of the joystick "hat", which is the wiimote directional buttons. Beautiful!
Download from uae-wii.googlecode.com but only after you have read the instructions on Wiibrew. Thereafter, join the project as a developer and improve on it!
Update: "Gouky" has released the source code to his version now, you can get that here. Better late than never!
