Three games.
The first one has broadband and narrow options and its based off the Bit Char-G franchise, too bad I couldn't get it to load for some reason after multiple tries.
The second one, I have no idea what it is because I couldn't get it to load also

.
The third one I manage to get it to work and its pretty nice. Based of the choro Q, your objective in the game is to smoke the other guy.
Five cars to pick, either a NSX or Oddessy. When you picked your car, you can see it on the starting point of the track. What you do is you click-hold and drag your car left and right until you hear the clicking sounds you hear on the pullbacks when the spring is turned too much, then you release your vehicle and watch it go. Try different launch techniques, sometimes you'll do wheelies, spin out etc. But watch out for obstacles, like tires, your opponent knocking you off the track etc.
Waaaah, I wan't to load the first two games

. If anyone has success please share with me especially about those games.
