first one is nothing special since you can achieve the same with file replacements and those songs are already in the disc.

second one is something to try out since the real differences come up with advanced techs. the steering did seem closer to AX so that's one interesting thing.

 Well, at least now we know where the song "Flags" is played.

And since configuring the steering wheel is a bit fiddly in Dolphin, here are a few indications on what to do:

-Reset calibration on both analog sticks. If you don't, the machine will decelerate when steering.

-You may be tempted to set the accelerator on Control Stick UP and brakes to Control Stick DOWN, but that will result in weird behavior when pushing both pedals as they will be assigned to the same variable. To assign the pedals to different values, set the brakes to C-Stick UP instead.

-To enable force feedback, set the Rumble option to Constant.
