Hello Timo! Nice to find a Penny Racers notification! Long live Penny Racers 64!!

So you propose that the All-Parts category does not include the special parts? I didn't figure that - nor did I attempt a run.. :-P I like this idea of a run. It is honestly the only I can imagine outside of AA-class complete. Maybe you could add that you'd have to start with only Class C unlocked?

About the Air-Duct: To be sure about your theory: Could one place 1-3 29 times in a row on the same track -> Restart their console -> Win a single time on the same track and get Air-Duct?

If that is the case then I agree that the 30 consecutive 1-3 placings has to be a part of the actual run. Not a part of some preparation / practice.

If the Air-Duct is based on pure RNG, then I think it is nonsense to make any ruling about it. Afterall, what are our sources that it is actually 30 races that is required? If you can get lucky to have it after 19 races then let that be it and go on.

A lot of this run would be repeating races on Alpine anyway as it is the shortest track. So you would definitely place 1st atleast 30 times on Alpine during this run when the goal is to unlock all parts. The most optimal route would follow this rule - even without its existence. Please correct me if you disagree!

I hope the mods will respond to this and make it a category. I know WMJ runs F-Zero X regularly and he is a mod on Penny Racers. Perhaps you could contact him?

I would strongly consider to do a run myself one day! - If I ever get a reasonable recording setup for my N64..
