This movie finishes the very 1st stage with 3 turbo uses (refills to 3). Note that there's looping stages with actually 3 different difficulty. You would need to use a "cheat code" to start from the hard one directly from the menu.
0x0018 speedometer, learn the values to make perfect shifts 0x0544 enemy pos, not the best but something useful.
-Enemies you need to capture has unfair speed advantage over you. So the fastest way to catch em up is to be slow while reasonably fast. This means you should be fast before they appear and try to hit the enemy without sacrificing more time to spend to recovery (avoiding slowdown) -Enemy car's moving pattern depends on your cars position. -Making a wide turn with your car around a corner makes a sound effect. Actually most of the time there's no slowdown.
Feel free to use this WIP.
