Won my first Anbernic 2 weeks ago!

Just came in the mail last night! I'm absolutely stoked. I never win anything in raffles or drawings so this is a sweet little first. I have an RP4Pro, but wanted something a little more pocketable for daily commutes or downtime at work. Needless to say; the RG28XX is perfect. My only question is:what's next? Is there a more aesthetic OS or way to view the game library? (Daijisho type) I'm fairly new to all of this so lmk what yall like for your devices.
