These may be the same websites you found, but here are links to scans of the packaging (in Japanese)

Mario's Egg Catch 
Luigi's Hammer Toss 
Princess Toadstool's Castle Run 

And here's an eBay listing with the American packaging for Castle Run.

This is crazy good!! 

If you need a secure link to the same set of manuals, you can use https://www.handheldmuseum.com/Manuals/index.html :-)

Awesome update! It's so cool being able to play these games on my phone. Keep up the great work!

Mego definitely did a better job with the Time Out packaging than Nintendo did with the Silver series. Here are higher resolution photos of Fireman Fireman :-)

ooh, there are cheat codes too! too cool :)

so cool. thanks!
