We are looking for tama-go ones but if you compare the charts to the list and to the tamagotchi wiki there is a lot of similarities they dont look like they change much between versions.
Look at Kutchipatchi's likes:
List: Burger
Pixle chart: Corn
V4 Chart: Corn
V3 Chart: Corn
iDL: Dumpling and heart cake
Memetchi likes:
List: Muffin (unconfirmed)
Pixle chart: Cupcake
V4 Chart: Cupcake
V3 Chart: Cupcake
iD L: Sunflower Cookie
Neonmoo, what you're calling the pixel chart is a V3 chart, just so you know. The older versions seem to have similar favorite foods, but on the Tama-Go, there is a lot of new food, and many of the likes were changed randomly. Like my list says Memetchi's favorite food is muffin when in the old versions it is cupcakes, and it even says on the packages that MEMETCHI LIKES CUPCAKES, but I saw a blog and the topic I saw years ago (but can't find now) that said it was muffin while I was searching. (I'll try to go for Memetchi on my Tama-Go next, I've never had her before) Here I'll put the revised list, and add exclamation points for the ones that have been reconfirmed on here.Boys:
Kinotchi: pudding!
Ahirukutchi: crepe
Mattaritchi: pear!
Kilalatchi: cereal!
Korokotchi: hot dog

Yay! Mametchi's favorite food has 2 reconfirmations!
Nothing happens when the character eats the favorite food on Tama-Go, but when the favorite comes up on the list, the Tama gives you a big smile. After you've fed the character the food, they get two happy hearts (or if it's a meal, a hunger and a happy heart, I think).
I edited this just in time to add Monpatchi's favorite food.
