DO NOT USE DEFAULT DB

Use a well-made mod such as World DB. Others are also good also, but world db has more stages, more riders and more accurate rider stats, which are updated many more times than with the default, which is edited 2 or 3 times a year.

Remember

DO NOT USE DEFAULT DB

And watch tutorials/pcm gameplay on youtube depending on language
