“shizzle for rizzle” is snoop dogg slang from the 90’s

thats because they legally cant include the cores in the steam version. You’re able to go add any additional cores you want, however.

Why not PNG?

most will just slow the rate your deck discharges (if you’re using it), you need a high output charger to actually charge it. Anker makes a few that will, i personally have the 737 and think its worth every single penny with the steam deck.
