Please suggest some cute retro games to play on SF2000 for my 8yo

The GBA Pokémon games are great, my 8yo loves them.

Harvest moon series is also a good bet.

Kirby games

Yoshi’s island on snes

Some cutesy games that I found.

GBA:

• Disney's Cinderella: Magical Dreams
• Disney's Magical Quest 1, 2, and 3
• Disney's The Little Mermaid: Magic in Two Kingdoms
• Disney Princess
• Disney Princess Royal Adventure
• My Little Pony Crystal Princess: The Runaway Rainbow
• a multitude of different Barbie games

MegaDrive:

• Ariel the Little Mermaid (I played this one as a kid, but I don't remember much from it)

SNES:

• Barbie Vacation Adventure
• The Great Circus Mystery Starring Mickey and Minnie
• Kirby Super Star
• Kirby's Dream Land 3
• The Wizard of Oz.

The Great Circus Mystery game was one of my favorites to play with my younger brother. It has an amazing 2 player mode where a second player can join at any time, which probably doesn't help in this case, but it's a great game to play together. Similar mechanics and style: The Magical Quest Starring Mickey Mouse. These 2 games (and the third game) are also on the GBA and listed above as Disney's Magical Quest 1, 2, and 3.

I've only personally played Ariel the Little Mermaid and Great Circus Mystery, all of the others I just now opened to get an idea of how they play to see if they're cute. If many of these don't fit the bill, I at least highly recommend the Magical Quest ones on either system. I hope this helps your search.

Mickey Mouse - Castle of Illusion

I don't remember specific titles, but I found anything with "Barbie" in the name on Gameboy through Gameboy Advance is much better than it has any right to be.

Spider Farmer 2000, eh?

I'm not sure what other games it has...
