Not OP, but can recommend two similar ones, data frog SF2000 looks like a snes controller with a screen on it, it’s cheap (~20-30 USD) but it gets a little laggy running GBA, and anbernic rg35xx is pricier but higher quality, and has a gameboy-ish shape (~60-70 USD) don’t know about any of the other ones, but those two seem decent-ish from what I’ve heard. Haven’t used them myself but they seem to be the most popular. Both have replaceable/upgradable batteries, but they’re not AA’s.
They’re mostly on aliexpress
Not to mention the interesting bits of info you can find just by looking into the CEO of Brave, Brendan Eich. Plenty of reasons with him alone for someone to avoid the browser and search engine.
The big one that he likes to keep buried is that he donated money to an anti-gay marriage proposition in California back in 2011, which is what caused some of the pressure for him to step down as Mozilla CEO back in 2014 after being it for a few weeks.
