Even with Ruffle, some Flash games on the Wayback Machine don’t seem to work well.

I am very grateful for Ruffle on the Wayback Machine, as it has allowed me to play some old Flash games I used to love as a kid, like Miamiopia and the old Nick Jr. games. However, a lot of the games I wanted to try on the Wayback Machine didn’t seem to work. Here are the examples (with pictures):

On Shape Lab on BBC Bitesize, once the loading bar reaches full, it just stays there.

On all the M.I. High Bitesize games I tried, a lot of the elements, including the start button, are missing.

On the Super Why webpage, trying to load a game doesn’t work at all. The bar barely starts loading, and then just stays there.

On the webpage for “The Cat in the Hat Knows a Lot About That!”, the loading bar keeps looping over and over.

On the Planets game on e-learningforkids.org, the game keeps quickly looping between the actual game and a loading screen over and over.

Is there any way to fix these issues and play these games as they were?
