How to earn lives in Pac Man World Re Pac?

Only found this online but it's for the original PS1 version: "Pac-Man can gain extra lives by collecting gold 1UP Pac-Man items, by earning them in the slot machine at the end of every level or for every 10,000 points scored at the results screen."

But I don't know what these gold 1UP Pac-Man items look like or how to recognise them, couldn't find a pic or any more information on it. Does it mean the gold coins you collect during a level? I thought those were for using in the slot machine.

Also does it mean you can only get lives at the end of the level or is there a way to get lives during the progression of a level as well?

And what does it mean the results screen, can we earn lives by getting 10,000 points while playing a level or only after finishing it?

Wikipedia says this: "He can find small fractions of health to replenish it in levels, as well as extra lives."

I was wondering if we can get new lives by collecting more fractions of health once we already have full health, but not sure. And if there is a separate in-level collectible that grants you a full life, what it looks like.
